Hi Everyone,
 
I am going to purchase Plantronics Backbeat Pro, which are equipped with Class 1 Bluetooth 4.0 chip, with apt-x support.
To be able to fully take advantage of these features, I have to find a Bluetooth transmitter, which is class 1 (for further distance) and with apt-x (for theoretically better quality).
Unfortunately, my googling returned only 1 result: AZiO BTD-V401 USB USB Micro Bluetooth Adapter, and it is not even 100% clear to me if it really hosts class 1 chip... and it costs fortune in Europe (we are talking about over 100Euro)....
 
Would you be able to recommend adapter like that ? Anything you have heard of or, even better, tried yourself and know that it provides such features ?
It doesn't have to be USB adapter. It can be a stand-alone transmitter with analog / digital audio input to hook it up to PC sound card output.
 
Thanks in advance!
 
EDIT: a theoretical question - such stand-alone transmitter probably will cause a lot of sound quality loses ? PC Sound card would have to convert digital to analog, then transmitter get that analog, encode as digital and transfer via BT... I guess it has to be far from perfect, but it is just my guess.

Bluetooth 4.0 is lossy. AptX is lossleess compressoin. Definitely worth it to get AptX

Sorry. I don't know anything about USB AptX capable bluetooth devices.

BUMP.
 
Still looking
Anyone ?
 
All I need is BT music transmitter with apt-x and class 1 chip on board.

Can't help but I'm interested in the same sort of thing

AptX over BT isn't lossless, but it's better than standard BT (SBC encoding).

CSR claims AptX is CD quality: http://www.csr.com/products/60/aptx

This discussion over at Hydrogenaudio says that " apt-X Bluetooth uses a bitrate of 352 kbps and thus preserves the full bandwidth of a 16 bits stereo 44 kHz audio stream." But that would seem to call into question over whether or not it can fully support lossless compression of CD audio.

I agree that its perceived audio quality is comparable to CD, but that doesn't make it lossless.
 
There's an "aptX Lossless" codec with 2:1 compression ratio. However, BT aptX has a ratio of 4:1. Its compression artifacts are probably inaudible, but technically it isn't lossless.

Thanks. Good to know.

I too have been looking for this, the only one I have been able to find other than the Azio is this one http://www.logilink.org/media/datasheets/BT0015.pdf.  Although, I can't actually find it for sale.

Does anyone know if there is a bluetooth transmitter device that I can plug into the audio output of my TV and use it with a Bluetooth speaker, such as a Jawbone or a Riva Turbo?

There are several such devices, but the crucial point with TV is that you need low latency transmission to keep video and audio in sync.
 
Here's a list of aptX low latency enabled devices, which imo would be your best bet:

Thanks james444

Well, I bought a Miccus Mini-jack TX4 to use as a bridge between my non-Bluetooth mp3 player and VOXOA HD Wireless.
 
Was quite happy with the sound quality until I accidentally dropped the VOXOA (one side became inaudible).
 
On its official website:
http://www.miccus.com/product-p/mmjtx-04.htm
the TX4 supports Bluetooth 4.0, APT-X and low latency.
 
I bought my TX4 on Ebay.

Be sure to differentiate between different products (all one character difference!).
The TX does not support Bluetooth 4.0 and APT-X.
The AX4 is the receiver counterpart of the TX4.
The RX is the receiver counterpart of the TX.

I pretty much came to this same conclusion. Great info. I wonder if hooking this up to my USB DAC makes any difference.

Check out the class 1 "Oasis" from Avantree dot com. It's being released this month. I have their Saturn Pro (class 2) and am pretty happy with it.
