Apt-X Bluetooth Receiver

WESBAR · Mar 30, 2012

Hi,

I know the One x outputs Apt-x streo bluetooth. Theres a couple of over the head type headphones that support this. what i'm after is an Apt-X receiver which I can plug my own 3.5mm headphones into. Does anyone know if such a thing exists?

I know you can get standard bluetothe receivewrs for this (i've got the SE DS200) but it does not support Apt-X.

Cheers.

A quick search threw this up

Although I've never been disappointed by the sound quality of my SE MW-600 through my HD2, I'll have to see what its like when I receive my ONE-X!

Just searched myself - found the Chord Gem at $799 (it's a high quality DAC as well), and the more reasonably priced QED LIVE uPLAY WIRELESS BLUETOOTH AUDIO RECEIVER for like 60-70pounds (apologies for the shouting, I just cut n paste that from the website).

EDIT: Just found out that the Samsung HS3000 has Apt-X, looks better than the QED since it has facilities for calls and also media controls...

EDIT2: Just purchased the HS3000, will let you all know how it is.

If the One X has a good BT stack, you will not be able to hear any aptx benefits, the DS200 is a good device and with a good BT stack on the phone, it will be CD-like quality.

Apt-x allows uncompressed data transmission of lossless audio files from what I can gather. From reviews I've read of apt-x sennheiser headphones, it's indistinguishable from wired headphones. I've had several a2dp headphones including ds200 and the quality just isn't there for me. U can definately tell the difference.

Which is not at all correct, the audio is compressed. The streaming rate is +300kb/s.

Many phones have poorly implemented standard a2dp, they stream at about 220kb/s, this is something which is will be improved, a +300kb/s standard a2dp stream is also just as good as wired. I know people who have done the comparison.

I was under the impression that AptX uses a different codec too, not SBC.

@pzboyz, is there a way of measuring the A2DP bitrate for a device?

It's ironic I only heard of AptX recently, when I bought a Foxl and opted not to get the Platinum version, thinking that there weren't any implementations of this spec yet. And a month later, it's in my new phone.

Well I can definitely tell the difference between bluetooth and wired (I have Sennheiser HD25-1 II's and Audeze LCD-2's).

@WESBAR: Samsung say that, but not on all their sites, in some they just talk about their silly EQ effects and make no mentioned of Apt-X. I saw it listed quite a number of places with specific mention of Apt-X.

Anyways, will confirm what it's like once I get them.

Yeah I've seen it mentioned on their site too. Got my phone now. Tempted to just order one. They're on ebay for around £26. They do a white version which will match my phone aswell! If these live up to the claims, they'll make a perfect partner to my Shure SE530's which have a short cable which usually runs into an extension piece.

Where did you order yours from?

NZtechfreak · Apr 10, 2012

Ordered mine from Ebay also.

If you order and get yours first let us know how they are!

How are you making the comparison? You quoted some wired headphones and none of the other equipment used to make the comparison.

WESBAR · Apr 10, 2012

Ordered! Will post a review when it arrives.

I'm talking about every smartdevice I've ever owned listening to bluetooth Vs wired (N95, N95 8GB, N82, i8910, HD2, Touch Pro, N97, HTC Desire, HTC Sensation, Galaxy S, Galaxy SII, Galaxy Note, ASUS Transformer and Transformer Prime, Google I/O Tab 10.1, Galaxy Tab 7.7) with a large number of headsets DRC-BT15, Moto S805, can't remember the model names but several of Nokia's best BT cans, a few other Sony headsets whose model numbers escape me. Bluetooth audio quality is not equal to wired on any of those devices.

I only mentioned the wired headsets so it's apparent the wired headsets are not the rate limiting step.

I've not tried it with my One X since I don't get it until next week, will be interesting to see is Apt-X lives up to it's billing.

Have a look in here.

It's arrived. Initial impressions are good.

Definitely sounds better than previous a2dp headsets I've used. After initial pairing I've noticed one or two occasional dropouts during the first minute or so of playback but it seems pretty stable after that. Swapping between plugged in and bluetooth with the included iem's doesn't highlight any immediate differences (only tried mp3's and aac files with Poweramp) which is good. Previous a2dp's i've used have been more constrained with throughput than the the actual headphones used with them.

Will listen to it a bit more over the weekend with better headphones (Shure SE 530's), higher quality source files and post some thoughts.

Thanks for the feedback, I have the receiver but won't have my One X till next Wednesday (lucky enough to be getting one for review that I get to keep).

It's meant to be lossless up to ~370kbps according to CSR (the people who developed Apt-X), so I presume for FLAC files you'll start to hear some differences, but for everything up to 320kbps mp3 there shouldn't be any discernible difference if CSR's claims are accurate.

apt-x is a codec used under the a2dp profile.

Hi

In order to clarify a bit. I believe the apt-x is a compression format, which is an extended codec to the a2dp profile of bt.

So you may be comparing apt-x to a range of codecs used under a2dp, where you also find apt-x.

Hope it sort the discussion a bit. And thanks for the input on devices.

Right guys I Love me music and the HOX straight out of the headphone out it's ok. My SGS Voodoo'd kicks its arse out of that water! I'm going to order the HS3000 and test the aptX technology with my TDK BA200 IEMS. To see how it differs.

Will give some feedback once I've had a play with it all.
