Headphones....

Did this thing not come with headphones? I don't have any in my box....

Every review on the web shows the same. This phone simply wasn't packaged with some...it's likely that you'll already have some anyways or you'll eventually get a better pair than they would have ever packaged.

You're probably right but I wanted to test out the FM Radio real quick and low and behold...

The no headphones is surprising, but with a retail cost of 450.00, you can't expect much. I would rather pay less and skip the headphones and mini hdmi cable than pay for them and not use them. I like the headphones I already own. Bundled headphones generally suck anyways. At least my iphone headphones suck that is.

i have these
i love these headphones

Also if you wana go alittle cheaper then the V-moda Vibe II, the V-moda Faze are extremly good too, thats what i ended up getting, they run about $49.99 and exellent sound quality and build!

I use super cheap OEM blackberry headphones I get off ebay for like $3 a pair. As far as comfort and sound quality go they seem way better than the other super cheap and kinda nice headphones I have

There's better IEM headphones than any of the V-Moda models for less $ or about the same price imo... MEElectronics M9P, Nuforce NE-7M, Maximo iP-HS5, etc. Head-Fi.org is a great resource for all things headphones. I just bought the MEElec M9P last week and I've been trying 'em out today, I got 'em for $22 w/S&H but I think they went back up in price to $35 (the others are around $50).
I think they're a noticeable step up in quality from the other mic-less IEMs I already had, Sennheiser CX300 and JVC HA-FX34 Marshmallows... Those two are fairly common at retail stores so if you've ever owned either of them you have a fairly good point of reference.
After reading a few threads at HF I ended up w/the MEElec because of the relative SQ to price, and the fact that they have one of the best cords of any IEMs under $100... Hardly any microphonics at all, virtually none if worn over the head (microphonics = cord noise when it bounces or rubs against stuff). It's got like two layers or something (one of them is translucent so it's obvious).
Pretty high quality stuff, nice hockey-stick shaped plug, nice metal casings, comes with 5 different sets of tips (regular single flanges in three sizes and dual-flange tips in two colors) and a bunch of other accessories including a nice hard case that's slimmer than most of those types of cases I've seen. Highly recommended, I like them a lot more than my Senn or JVC (and I paid like $50 for the Senns around 5 years ago, $20 for the JVC recently). I've not been able to test the mic yet since my EVO hasn't arrived and I didn't feel like doing it with the iPod touch's sound recorder or something.

Does the V-Moda Faze have call answer functions?
EDIT***
I went ahead and bought the FAZE and wow, the sound is great and yes it works for answering/hanging up calls as well as playing music.

Anyone know/test normal apple ipod headphones? I have a pair and they're my usual set and I was wondering if any of the integrated controls (mic, volume up/down, push to pause etc.) work or if anyone knew.

Today I went down to mobilecityonline located in Canal street and purchased the Sony Ericsson MW600 bluetooth stereo headset for use with my EVO 4G.
At the moment it is charging [at least 8hrs], but I wanted to know if anyone it using this particular device?
Once I get it up and running, I will let you guys know how compatible it is with the EVO. Hopefully all the functions will work and I don't have to return it.
update 06/08/10
Well with alot of playing around and trying a few different audio apps, I got the MW600 to function the way I wanted, which saved me from returning it.
My main concern was being able to use the controls on the device, and I was only able to do so with an app called bTunes.
I had no luck with the stock Android music player nor with another App called
Audio Player WithEQ Platinum
Although those two did play via the bluetooth unit, I was not able to use none of the control functions.
With bTunes, I was able to play, pause, and use the forward and backward functions.
On a side note, the headphones that came with the MW600 are very short, but they sound very good. I ended up using my Klipsch Image S4i which I was using previously with my 3GS.
Hope this meets you all well.
Cheers !

my iPhone headset works but the VOL +/- doesn't work

anyone have any experience with the inner ear apple headphones they cost 69.99$ i ordered a pair with my iPad(figured i could use em with all my gadgets)

The controls on the Ultimate Ears Superfi 5Vi's are able to pause/play music along with voice dial and answer/hang up

Those V-modo's look cool, but honestly for the price they lack key features:
1- IN-line volume control. not a digital one like iphone headsets, but a slider on it, like the OEM mogul shipped with.
2.- for that price, and especially since it is coated in so much metal, it should have an inline radiation deadener- nobody wants radiation from their phone being transmitted right into their eardrums, especially since the 3.5mm port on our evo's acts as the FM antenna --- that is just insulting

At least from my experience with this device....
You are better off with using bluetooth headphones that can do MP3 bluetooth decoding and using Meridian as the music player. The truth is that while the headphone out is decently clean, it has a relatively high output impedance and not much driving capability. You are much better off getting some headphones with imp between 32-60ohms and at least 97db efficiency and not getting something too nice to use direct.
There is also the issue of when this is hooked up with grounding loop noise if you hook up your headphones to the output. Why the engineers who would put together such a media centric device would not think of such simple things is beyond me, but the iPod does it too and it is a pure music player.
If you happen to use a headphone amplifier, then you can use what you want because the audio signal will likely be free of much ground noise and have a really nice spectrum to it (much better than even my line out was on my iPhone....though not better than my modded iPod Touch).
If someone wants to work on USB host audio drivers I would be elated, willing to help as well. I can even make a custom hardware I/O box for the Evo!

I bought the Bose in-ear ones from Best Buy. I'm going to return them though. The sound is not as vibrant and alive as from my stereo BT set (S9-HD)

Is the volume using the iphone headset loud enough for you? I've tried it and it's too low and the people I'm trying to talk with sounds like they are fading in and out.
I'm thinking of returning since I can't even use it as a phone with the wired headset.

[Q]"Best" Headset for Note?

Hi all,
I'm wondering what headset (Bluetooth/Wired) you use for your Note? I'm using Marshall Minor, but I still find the volume not loud enough.
Would any of you recommend something else? I live in Hong Kong which is fairly noisy, so something that has good volume would be great.
Thanks in advance!

I haven't got a Note yet, but I use the Sony MW600 bluetooth headset with my HD2. And I'd be lost without it - best thing I've bought!
No problems syncing to the device, it has remote control (pause, next/previous), hands free talk as it has built in mic, and comes with in ear buds, which are very good indeed. They block out quite a bit of external noise too, but you can plug in any headset you want to it if you want to go to higher spec headphones. Battery lasts about 10 hours continuous use, and it will re-charge of your Note's charger.
I'm not an audiophile, but I do like music. And it does me fine.
http://www.handtec.co.uk/product.ph...w600---black?gclid=CLftmIS1n6wCFYEZ4QodOzpc_Q
Edit - Just had a look at the Marshalls, and these would offer a tighter fit in the ear then the Marshalls, so would block out more external noise. I wear mine in work, even if i'm not listening to music. I work in the print industry with loud machinery, and they are better than the ear plugs we get given, which reduce external noise by 27 dB. If I'm listening to music in work while my machines are running, and you want to chat - then you ain't gonna get through unless you're in my face!

That's a pretty sweet headset. How much does it stick out after you put it on? Does it get loose easily? I used to own a pair of the Sony is800 headset and it would fall out easily. I was wondering if this is the same.

My previous headset was the Sony Ericsson HBH-IS800
Compared to the Sonys:
- They seem to fit better in my ear (they come with 3 different bud sizes)
- The earbuds are slightly larger and so I guess they do stick out a little more, though I haven't noticed any issue with it
- An extra 2 hours of call/music time
- Have FF/RW controls as well as volume adjust (The Sony's only have Play/Pause/Answer)
- I haven't had any issues with people hearing me or me hearing other people when using them, but I've yet to test them somewhere really noisy
- They come in Red (if that's your thing)

Thanks for the comparison. How's the sound quality compare to the Sony?

I was thinking about this but didnt bother getting one once i saw the Note, not as big as the press would have u believe!
I was considering the NOKIA J - i has a small clipable dock so i wouldnt have to have it in the ear all the time...
3 months standby time
Auto answer when taken out of dock
Few more feature i cant remember now, worth having a look at.

Besides being a gadget phone nut I am also a sick buyer of headsets. I have been in search of the perfect headset forever ..
There is one by Sony that I love the way it fits. They don't make it any more and every now and then I find one on eBay ..
I have the Sennheiser bluetooth headset. If you look hard you can find one new on eBay most of the time for about $60 .. I like that one a lot because I have small ear holes and those go on the outside of your ear ..
I also have 2 Bang & Olafsen bluetooth headsets .. One left ear which I am keeping and the other right ear which I am gonna sell when I find it .. I also have the wired Bang & Olafsen head set. I read that it has a teeny tiny microphone somewhere .. I don't know if that is my model .. use it for listening to music ..
I actually have a box of discarded bluetooth headsets. I should put them all together in one lot and sell them. Maybe I will do that today. Don't know if I can find all the chargers though .. They are all discarded because I find them uncomfortable to wear.

For music or movies I use the Sennheiser M400s which have a nice balanced sound and good battery life. For calls, it's hard to go past the Plantronics Discovery 975 - small and sleek, super comfortable to wear, and really good battery life (especially with the included charging case).......

I can't wear anything that doesn't go around the ear. And if it goes in the ear, ugh. After a half hour I have to take it out because it gets painful. Maybe if I had bigger ears .. or Man Ears .. it wouldn't be so bad. They are doing hearing aid implants now, maybe they could do a little bluetooth implant ??

Any chance you can take a picture with the headset on? I want to see how it looks on and have an idea on how much it sticks out. I cannot find a pic or review anywhere for this headset.

I got these 2 days ago from Amazon:
amazon.de/Philips-SHB9001-00-Bluetooth-Headset/dp/B00424O4RU/ref=sr_1_1?ie=UTF8&qid=1320610417&sr=8-1[/url]
the quality while talking is not the best but its enough for me.
Despite the positive comments about the quality of just listening to music, i can hear some "scratches" when a song gets "heavier". This is my first BT Headset so maybe its normal for BT headsets, or i just overlooked a setting i have to change in the Software.. Hint, anyone?

Do you have a budget in mind? I think we can offer better suggestions if you give us a budget range.
I use Sennheiser IE8 connected to a Sony/Ericsson Bluetooth receiver on the go, and a small digital analog converter/amplifier by NuFore together with the headphones when working.

Hi, thanks for replying. I do not have a budget in mind, my usual principle is to pay what's worth its salt.
So far, everyone's recommended bluetooth wireless headsets, I'm not a big fan of charging stuff, having need to recharge my phone nightly already. But if there are no better wired devices out there, I might as well get Bluetooth because call quality is more important to me than music quality which my Marshall Minor does just fine.

I'm looking for a $100 max wired in-hear headset with mike and very complete remote too. It seems Android is not very friendly with those at all, so I'm thinking I'll have to go Bluetooth. What I found:
- http://www.etymotic.com/ephp/mc2.html, if their software works on Note (untested)
- a-JAYS One+, coming in Dec.: http://www.jays.se/products/earphones/a-jays-one-plus.html (uses software too)
- Sennheiser just confirmed they have nothing wired.
- Klipsch: Image S4A http://www.klipsch.com/image-S4A-headphones being adapted for S2, Note = S2 ?
- Samsung: told me to go f... (...ind a solution by) myself
Soft: https://market.android.com/details?id=com.kober.headset , and others, look for "headset control". This one has a trial version, yeahhhh ^^
EDIT: I'm putting everything worthwhile I find in this post, so as not to spread it all over the place.

does the Gnote able to accept the standard wired headphones w/mic from other brands for example: UE? i am on galaxy S and i have been searching for headphone w/mic to replace the original ones from samsung but as usual when i connect other brands of headphone w/mic to my S; all i can hear is the music.. whenever i am making calls the headphone fails me...

High End Earphones (IEM) with remote controls for SGS3

Hi Guys,
I'm not prepared to compromise any more on sound quality than I have to and I like to use good IEMs and MP3 players.
Recently, like the rest of the world, I've started to use my mobile phones as my daily audio driver more and more.
I’ve never had a serious pair of earphones with pause/play/RR/FF controls, this would be a godsend and I would like to know if there are there high quality earphones with this feature out there that actually work on Android?
I will use them with my mobile phones Galaxy Nexus & Samsung Galaxy S3
I saw this thread http://forum.xda-developers.com/showthread.php?t=1695717 about high end IEMs but they aren't discussing android controls and I'm following AndrewWilley http://goo.gl/eclr4
I'm also checking out the http://goo.gl/4jBfc as an option and I will be able to plug these into my Denon C710's but I cant tell just how much they will impact the sound quality.
I'm also talking about quality IEMS above the Beats by Dr Dre range or the a-jay One+ headphones.
I'll be happy to know if anyone has any ideas

I am an avid record collector. I think regardless off what we use we are still at the mercy of our dsp. Headphones become uncomfortable, while earbuds offer very little low frequency response. I downloaded an app simply called equalizer and use the LG HBS 700 Bluetooth headphones. Not bad for 69 bucks. Just another avenue.

I've opted for a custom iem - (JH Audio) which also comes with a cable with Mic and one button control. I'll pair that with the Jays Headset Control app and that will be job done.

Tapa.

Just to widen the choices the new T-Peos H200 comes with a secondary, single button mic equipped cable. You have to order them straight from T-Peos in Korea though, or though one of their online resellers.
A bit lower on the totem pole would be the cheapo yet good Brainwavz R1 or the upcoming R3.
The new Meelec twin hybrid might work too, but not so sure it has a mic or not.
Lastly the Belkin iPhone controller adapter works well without compromising much on the SQ side IMHO.
Good luck.

That's a good thread, thanks for the heads up.
I'm currently using the Etymotic HF2 which is listed on it:
The sound is clear but they really need a headphone amp to increase the volume which without can get lost to background noise when commuting.
I also had the Puresound ClarityOne (not listed on that thread) which developed a frayed cable after only 4 months.
The cable is thin and the connection point to the 3.5mm jack is the point of failure.
The customer service from that company was so ignorant I would NEVER recommend them to anyone to cough up over £100 on them.
I'm stepping up into the CIEM arena and see what the fuss is about.
Thanks again.

the T-Peos H200 look good and I read a positive review of them here http://www.headphiles.org/index.php?t=msg&goto=265151&

If you like full sized headphones like I do, I highly recommend Wireless Rythym by Miikey Stereo. The sound quality, bass response, efficiency and ease of use is out of this world.

I got my set at Fry's for $50. I can see them being a problem with someone with a large head though, as the cord isn't very long. I also have experience with the Moto S10's which are also nice.

Sony Ericsson MW600 Bluetooth. They are in-ear earbuds but you can simply unplug them and plug in any other headphone that have the 3.5mm plug turning them into Bluetooth. So you can take your favorite wired headphone and make them Bluetooth. I wear them everyday and they are only $40-$50 on Amazon.

Only annoyance is the non-standard charging plug. Would've been better if they'd used a mini or micro usb port.

I really like my chinese BH-503 headphones. It's seems to be original Nokia, but so cheap on chinese shops (you can easily find it on ebay). Good sound quality and work time.

I've been using these for about 3 years without a problem. Paired with Poweramp's equaliser, you can really tune them to suit your taste and genre of music. They're also decent on battery, cheap, and eady to modify.

I bought a pair of Motorola S305 headphones, they are over the ear style, the band goes behind the neck, they charge with standard micro usb, the sound is decent, a little static in my ears on phone calls, but people say they can hear me better than on my phone alone. I've recommended them to my friends, and four of them bought them, all but one still loving them. The other sold them for inner ear bud style ones.
I'm still using mine, still loving them

Do i need an amp for my headset?

Hey Guys,..
I just ordered a new headset from sennheiser.
I red somewhere that smartphones and mp3 players might not have enough power to make your headphones sounds nice at higher volume.
I cant seem to find any figures for the note 2 that i can use to do the math, so does any one know what the output is of the note 2?
Or perhaps someone has already tried this?
I bought the sennheiser 449, and was looking to add a FiiO E6 IF needed.
Thanks.

The phone should power the headphones, as it has a Wolfson DAC like some of the older model iPods, and a lot of people in the audiophile community claim the iPods with the Wolfson DAC were the best sounding (a little bit warmer and they give an overall better sound in comparison to the audi chips Apple are using nowadays from Cirrus Logic.
Try the stock player when they arrive and play about with PowerAmp and Jet Audio has loads of extra controls for sound settings etc, adding an extra headphone amp would boost the volume and give you a little more bass but at the cost of adding extra bulk, which sometimes isn't a good thing if your on the go all the time! Also apparently in the future BBE may be porting their SoundMax app from iOS to Android
I have been looking into getting a Note 2 for daily use and music, (trying to find an app that will play apple lossless!) and I also want to try and avoid adding the extra bulk of a headphone amp, the phone is big enough as it is Headphone wise, if your a bass head there is the newly released V-Moda M-100 which have been getting rave reviews, there is also the older V-Moda M80's which as still really good for the money (about the same you paid for your new Sennheisers). I have been looking at the AKG K550's a real nice set of headphones, they certainly look the part, and they are apparently great being powered by a Mobile, they are also closed back, so not much sound leak when your out and about. Hope this helps.

the only thing you should look at when buying new cans is the impedance (measured in ohm). in your case the impedance of the sennheiser 449 lies between 35 & 45 ohm. so, no problem to drive them without a dedicated headphone amp on smartphones and mp3 players respectively. to give you comparison, there are headphones with several hundered ohms of impedance. for these a headphone amp is highly recommended

right thats what i wanted to know because one youtube vid said that you DO need an amp if you are going to use it on your smartphone.
but i will give it a try without.
thanks.

Nope it doesn't require.... I have gaming stereo headset... Big in size, it works well in my nexus s... And must be working in note 2... Note 2 is using newer version of Wolfson chips

I guess, you don't really 'need' it, but if you have a portable AMP, it always make your headphones sound better.
