stereo bluetooth 3.5mm adaptor

I was thinking about buying one of these.
Does anyone else have one? Are they an good?

I have just a basic usb to 3.5 headphone adapter, and I use iPod headphones.
Sounds great to me.

Yea, I bought those and they are being shipped to me right now.
But I think that the stereo bluetooth adapter seems pretty convenient, no?
If HTC shipped a bluetooth adapter like this, I wouldn't complain about the lack of a 3.5mm headphone jack

Or you could just get stereo BT headphones and forget the wires and adapters!

No stereo bluetooth headphones can compare to my Shure earbuds.
Plus I think that most stereo bluetooth headphones are clunky.
Do you have a nice pair though? any recomendations?

I got one from ebay as well. I paid less than that, but it's still the same. They all are manufactured in China. I use mine everyday. Good sound quality, works right out of the box. I haven't really had any problems.
I only have two complaints. 1. You cant use them while charging, as the charger shown in the third picture is plugged into the headphone port. Strange, yes but it works. That is not really that much a problem, because it has great battery life! 2. No matter what I do, I cannot connect it to my computer to stream music from my computer to the A2d2p adapter. (or whatever it's called, lol) If you come up with a solution after you get yours, please post, or email me.
For me, price was an issue. I didn't want to spend a whole lot of money to listen to music from my phone, but I wanted good sound quality. Regular Bluetooth Stereo Headphones are expensive. For me, this was the way to go. I bought this and a pair of Sony wrap around headphones, and I am rockin'. I think you will be pleased.
**edit**
PS - I have attached the manual I got from a Chinese Suppliers site, as one doesn't come with it. At least not with mine. (Maybe thats why I got mine cheaper, lol)
PSS - And you know they are not only headphone adapters, but can be used for calls as well. It is kind of awkward to hold the adapter up to talk to someone, but I usually just clip it on my lapel. OK, done editing now.

Nice! Thank you for the information!
I think I'm going to get one, I just have to be careful because most of the ones they are selling on Ebay only have UK outlet plugins. I live in the US, and it looks like you do too by the picture of your plug.

I have these:
http://www.amazon.com/Sony-DRBT21G-...?ie=UTF8&s=electronics&qid=1246133334&sr=8-29
Great sound, comfy and durable as hell.
But I think im going to try out these next as I want something smaller and lighter, Im still shoppin though for a newer pair:

Cool dude. The Voyager ones look nice, but I think I'm gonna go the cheap route and just get the converter.

I have one of these:

It's a Sony Ericsson DS-200 which I bought last year specifically so I could plug some decent headphones in!
I think it was fairly expensive - about £50 when I bought it, but it has worked great with anything that I've wanted to pair with it, including my Excalibur.
But it's far better than using a wired headset with a 3.5 jack in my opinion, because if you use "proper" earphones that come with a long-ish cord then combine that with the long-ish cord from the wired headset then it makes for some nightmareish tangles! Using A2DP seems like freedom in comparison!
Highly recommended

Lol about the longish cord, gave up on wired headsets as the ammont of times i'd rip the cord when cycling, i'm using STAK semi enclosed cans made for 3 network they were cheap bout £30 and give loud playback with comfortability and like post above a2dp makes listening to music far more enjoyable skippin tracks in an instant answering calls in an instant...
BT is the deffenat way to go
Then cap it off with PocketPlayer....

I'm using Sennheiser CX300, not audiophile grade by any means but certainly better than bundled headphones or stuff like that, they're great.
I love impressing people on the bus by hiding the A2DP receiver in a pocket and then watching a movie or something on my phone, I've had a few people who were watching over my shoulder anyway ask me how I was listening to the sound! Hehe

Improved sound quality with fiio e6!

I bought a fiio e6 on amazon and sound quality has improved tremendously. Even with my a2dp receiver in my car, the improvement was great. Any other experience?

What kind of headphones are you using? i suspect that makes much more of a difference than the amp

I'm planning to get an E6 by the end of this month. Together with AKG K240 MK II. I will need the amp anyway, but it'll be good to know what ear-/headphones you are using.
Sent from my GT-I9100 using XDA

Just tried my E6 on my i9100. Absolutely no change at all. Tried 5 different IEM's and 2 different headphones, they all sounded the same.

Maybe your E6 is broken!
I use it with akg K317 and in my car with a beewi bba100.

I've ordered an e5, which I should receive tomorrow, from what I've read the bass boost on the e5 is better than that of the e6.
I'll report back on any change on the sound quality, although don't expect anything in-depth, I'm no audiophile

without a proper lineout from the phone, the sound will either be same or worst in most cases. Because what youre doing is amplifying an amplified signal. So, if the amplified signal from the phone is bad, i'm pretty sure your external amplifier cant fix that.

You would need the Samsung official car dock for true line-out audio. Either that or make your own cable like the one here: http://forum.xda-developers.com/showpost.php?p=20710266&postcount=14
Maybe Bluetooth audio would also work, if you have a Bluetooth receiver with a decent DAC.

No matter what you use, it will not improve the overall sound of the device as it uses a cheap and crappy sound card. Any sort of amp including the Fiio E6 only brings EQ to the music, not to mention you actually lose sound quality because your using a jack to jack method unlike the iPod where they have special cables that connects directly into the DAC of the iPod because of the special provide cables which over-passes the direct headphone jack port. (Search up Fiio L9 Cable) Also when using the jack to jack cable that's provided with the Fiio E6 it lowers the loudness of the sound when connecting via phone to the amp.
Of course then there's the human ear, if you feel like it sounds great, good for you but in reality the sound is worse with EQ added to make you think it sounds great.
If your an audiophile you have to accept that the SGS2 isn't the best music device. Cowon for example or the SGP are good sounding music players. It's a waste of money to buy a Fiio E6 Amp unless your using an iPod to be honest cause it significantly improves the iPod devices.
That's my 2 cents, take it or leave it as you wish.

Yeah, I noticed no change in sound quality with my e5. However it can make it a LOT louder, so if that's something you need, you might still want to consider getting one of these

The galaxy s 2 does also have line out which bypasses the headphone jack (for example the samsung car dock does line-out over the micro usb port) but there doesn't seem to be anything available to buy to do this without the dock. However as claimui said you can make your own cable too

[Q] Behringer UCA202 DAC - sounds horrible compared to headphone jack/bluetooth

So I found a Behringer UCA202 DAC online for really cheap and thought why not try it just for fun. Everything I've read says having one can help a bit and I figured at the least it would sound the same, but I plugged it into my Nexus 5 via OTG then plugged the AUX cord to my Jeep into the DAC and all bass and pretty much any other level of detail is gone from my music whether it's from Pandora, YouTube HD, or FLAC audio files. Audio sound quality is equal to listening to music over old mono bluetooth, you hear it fine but any highs and lows are removed. Has anyone else used this DAC that could give some suggestions?
Otherwise it's just as I assumed, DACs are pointless on good quality phones and that's why I can't find any DAC threads with the Nexus 5 involved.

Yes it has a DAC but it's not meant as a stand alone DAC. It's an interface or soundcard. Does your phone have enough juice to even operate the thing? Also for a device that sells for less than 30 bucks what exactly where you expecting? Get a real DAC. You will notice a huge difference. Until then do some more research on what you have and see if your meeting it's power requirements.
This is actually a pretty good review of the unit with lots of technical info.

While I can't see power being an issue I suppose I'll test with my Nexus 7 and laptop. I know it's a cheap DAC but I've read many reviews using this DAC with tablets and phones for car audio, along with the nwavguy in-depth review and testing showing how it's not a multi-hundred dollar unit but still does amazingly well. My issue is it doesn't even sound decent. It sounds like I'm playing rap/hip-hop through an old Nokia on speaker phone, you can hear it clearly but there's no depth.

So I tossed this DAC in a closet after I got bored of trying to make it work right and forgot about it for a year or so till earlier today when I found it while cleaning. My Nexus 5 has been retired and serves no purpose other than a security camera now. I now have a Samsung Galaxy S5 and an RCA Maven Pro tablet. The RCA Maven Pro is an 11.1inch 2-in-1 Android tablet with detachable keyboard for around $120. You'd assume it's horrible thanks to the brand and price but they managed to cut corners in all the right places it seems. Downsides are no GPS, 1GB of RAM, terrible cameras, and a horrible speaker. Other than that it has faithfully replaced my $1200 laptop with zero issues other than adjusting to ditching Windows.
Now back on track when I listen to music I'm either using an aux cord plugged into my work truck or bluetooth when using headphones or in my new car. When doing a side by side comparison bluetooth, to no surprise, shows no difference between my Maven and S5. However when using an aux cord the RCA doesn't put out as much bass and highs are... I guess not as clear? I think audiophiles are insane most of the time so it's hard for me to describe when I do notice a difference. Anyways I plugged the UCA202 into the RCA's USB port (no OTG here, it has a full size USB port) and plugged my Sony MDR-XB950BT headphones in to it with an aux cord (these headphones are 100% passive when wired, no bass boost or other enhancements) and sound quality is just as great as my S5, all bass and highs are restored. Just to further the test I plugged it into my S5 and did the same test with the same results. These are the same FLAC song files from the same network location that my Nexus 5 was playing a year ago.
The whole time the issue was something in my Nexus 5. What it was I don't know and sorry you guys I don't plan on investigating, I just wanted to inform everyone that the Behringer UCA202 is in fact a quality budget DAC since this thread is a top Google result for "Behringer UCA202 Android". If you have a cheap device that you want the audio to be on par with the high end phones this will do it, and for my original purpose of at the same time giving a bit of amplification for a weak head unit without distortion it does that decently too. To finish this off I am NOT an audiophile. Just a human with human hearing that likes songs with bass on car head units that weren't always designed for it (I glued a 80mm CPU fan to the back of the HU in my Jeep ) So take my finer details however you'd like.

the DAC works great for my Nexus 7 2013 model.

maybe otg cable is sh1tty

TESTED USB-C headset for 10$ that works

So, i saw lots of discussions around for a usb-c headphones that actually works with pixel 2 (mine is pixel 2xl)..
I ordered long time ago this usb-c headset from AliExpress, and forgot about it, then i received it today.. And it wooooorks.. Its actually really good (not saying high end headset good) but high volume, definitely noticeable bass, and very cheap (about 10$)..
So the secret was when i was searching for something that works with pixel 2 is to have CDLA (maybe a dax feature or a driver in it)..
Below you can see its picture and a link.. but also you can just search for usb c with CDLA on AliExpress..
The link:
Original Letv CDLA Earphone Letv 2Pro HiFi Chip Inbedded Continual Digital Lossless Audio Type-C for Xiaomi 6 Gold Galved Mic
http://s.aliexpress.com/z2aAjyMf
(from AliExpress Android)
What i don't like (but can live with it since its that cheap) is that its not in ear, its more like the shape of apple's one's.. And the mic is on the wire of the left ear (strange given that am used to the mic being on the right ear wire)
Honestly, the main reason for me to use it is that am on the phone a lot, and i want a quick plug and play mono headset, so am going to cut off one of the ears speakers (mono conversion).. And with it being that cheap, i don't mind the cutting (at least not a 50$ plus for an earset that i will end up cutting)

BAHAHA Looks like they took their iPhone headphones and put a USB C on instead of a Lightning. But having used the apple ones I might be interested in a pair since I kinda like em.

Louder than any normal 3.5 with an adapter, clear enough (but not high end clear), with a very noticeable bass (which i like, but again not high end bass)..

Instead of a dongle it should be an adapter that is cordless. Just the input and output on each side. Probably lose it even faster haha

These are the same headphones that come with the LeEco S3, Pro, etc. I have them and they are very impressive. They truly sound better than earbuds in the $100 range.

Hahahaha.. But mmmmm should google pay me then ?

Back at low price, I'm going to buy it!

Music worked but microphone didn't. Anyone else have a similar experience?

Yeah..mic don't work properly during a phonecall. The other party I called said that there was a loud annoying buzzing electrical noise when I use this headphone. I bought 2 pieces and both had the same issue. Disappointed

This will change my idea... Damn

wanted to buy this until i saw the price.........

Yaaaa noticed that too.. Sometimes the mic doesn't work.. Agree with most here..

Other suggestion for type c earphones working with mic?

Can't get these to work on my phone. Is there an option I haven't enabled, or is Flash Kernel interfering in someway maybe?
Can confirm they work on my computer so its not the headphones themselves
EDIT: so interestingly I flipped around the usb cord and it works haha. Weird how it works one way and not the other.

Mine arrived yesterday and the microphone works perfectly.

Headphone Sound Quality ?

Hi guys,
I've been reading contradicting opinions on sound quality from headphones output for this device (adapter actually). How would you rate it in terms of loudness and overall sound quality? Also, do you find it inconvenient to use in any way?
Thanks,
g

i dont believe thats contradicting opinions... i tested 3 or 4 handsfree (xiaomi noise cancellation usb-c, sony mdr nc-31 em and other cheapest) and i did a comparation with xperia (z3 and z5) and sound is more natural on xiaomi; loud is it enough (if u dont like ,u can root and increase manual the volume until u can damage ur ears)...is a very good phone about sound

Thanks 7tky. What I meant by contradicting, is that some reviewers claim that sound from wired headphones is awesome, and some claim it's crap. That's why I wanted to hear opinions from people that actually own and use this phone.

I'd say sound from this phone is pretty damn good, and GSMarena's tests confirm that. The phone can power pretty big headphones too. It powers Sennheiser HD6XX's pretty well and those are 300ohm cans. Obviously not close to as clear as a dedicated DAP/Amp combo but still impressive that it can power such headphones to near uncomfortable volume. Also according to a review that I can't seem to find anymore, the phone outputs analag signal from the USB-C port so the dongle doesn't have a DAC and Amp in it. All it is doing is turning the USB-C port into a 3.5mm jack which probably explains the capability to power my Sennheiser's.

Yup, I looked into this myself. I had a DAC and AMP combo for my old Moto Nexus 6 (I wasn't happy with the sound quality of the jack). This phone is surprisingly nice. I ended up buying a few extra USB C headphone adapters straight from Google (the official ones for the the Pixels were $9 when I got them). I haven't needed my DAC and AMP since switching.
And from what I've seen the DAC is internal on this phone (as opposed to the Pixel 2 which needs the DAC to be in the dongle). Idk if that allows the port to send more power straight to the headphones or not. But I'm happy.
I thought I would get annoyed by the dongle, but I ended up just ordering a few of the Google ones and keeping them on my headphones.
Plus, Viper4Android works fine for me for some additional tuning of audio (I'm using AOSP ROMs though, not MIUI, not sure if it works in MIUI).
Keep in mind I just use some Klipsch earbuds (R6, X11, and AS-5i), nothing that requires a crazy amount of power to run.
Hope this helps.

Ok, I bought the phone and tested it for a while now, so thought I might share my experience here...
With global rom phone came with (unfortunately, I don't know the version), sound quality was great, but volume was low. Further, it had a weird bug - when I was listening to music and notification cut trough, volume would jump much higher. I could easily recreate the bug by playing music, then going to sound settings and touching slider for ringtone/notification volume, then back to music. Volume would jump higher every time. Some googling reviled that lots of people experienced similar volume jumping bugs.
OTA update (again, I don't know to which miui version) fixed this, but volume was still relatively low. When I say this, I'm comparing it to my previous devices. I'm not trying to fry my ears, though it's always nice to have the option as some music is simply mastered to much lower volume, especially older stuff.
Now I'm on lineage and volume bust is just what miui was missing - few notches higher. I listen modern pumped-up stuff 2 or 3 steps below max, and crank it up to max for very low volume old stuff. Perfect balance for me.
I guess tweaking the correct config file would adjust volume limit on miui. If anyone knows how to do that, please share, it would be much appreciated.
If someone's curious about it, I'm using zero audio carbo tenore earphones.

My audioquest Dragonfly usb DAC stopped working after a MIUI upgrade on my mix 2 since the summer. That is, the phone recognises the DAC but the sound quality light stays red (instead of say, indigo) to indicate no signal.. Updating to MIUI 10 made no difference. I've confirmed it works with the 2S running Android 8 opr 1.70623.032 - My Mix 2 has opr 1.70623.027 and he meeting if that's a difference or if anyone has similar issues of a USB digital audio converter not working on their Mix 2?

Is the google dongle more sturdy? i have a Brainwavz HM5 which have a thick cable and the flimsy cable in the dongle supplied with the mi mix 2s feels like it will break any second from the weight of the cable on my HM5.

i skipped the original adapter and buy a new adapter(it's a dac hidizs sonata hd )
and use with my earphones is 1more triple driver.
no comment for that, oh i just forgot that, 1 word - perfect :v
