I recently bought some Sony MDR-1RBT headphones which can be used via audio cable, but also via Bluetooth. They support BT 3.0 with A2DP and use SBC or AAC as codec.
Unfortunately they do not support APT-X, but they have been tested much better than the Sennheisers which do support APT-X.
So, now I am looking for a USB dongle to feed these headphones via Blueetooth. Thus I need a BT dongle that supports 3.0 or later, the A2DP profile and AAC. If the dongle would also support APT-X (for the future) that would be awesome.
Unfortunately I cannot find any dongle that satisifies these simple requirements.
Well, I wonder whether the codecs that are being supported depend on the hardware or actually only on the driver/software stack? I am using Win7 mainly.
So the questions are:
Can I buy any BT 3 stick that supports A2DP and can that be "convinced" to talk AAC by using the right software? Which BT software stack would do the job?
Any other recommendations?
Not sure about AAC, but the list of AptX compatible dongles is here: http://www.csr.com/technology-solutions/av/audio-products-powered-by-csr-aptx/bluetooth-transmitter
So I got a sweet pair of bluetooth A2DP headphones for a sweet, sweet price (Motorola A805, if you were wondering). They sound great paired with an iPhone.
However, when I pair with a computer using the latest and greatest WIDCOMM drivers, the quality is quite poor, almost un-listenable... clicking, popping, scratching. The remedy on one machine was using BlueSoleil, another bluetooth stack, as there is an adjustment for the Bitpool settings that allow you to jack the quality up. Sounds great. However, the bluetooth chipset in my other machine is not supported by BlueSoleil... so I'm stuck with the WIDCOMM stack.
So the question is... Is there an undocumented way to turn up the quality for A2DP in the WIDCOMM drivers?
first question on SU, usually lurking on SO.. =]
Even bluesoleil does not get the best of the A2DP sound quality. I tried it, and it was pretty fustrating when I hear the same limitations on the sound quality.
I found this article:
toshiba bluetooth stack allows you to set the sample rate - meaning the quality.
On 328kbps you get the best of it, which for me is like wired sound (I cannot get the difference). The only drawnback is that it can be quite tricky for the toshiba bluetooth stack to find an internal bluetooth device. I have a DELL INSPIRON 1520 and an BELKIN USB dongle. The DELL's bluetooth is not found but the BELKIN works fine. Give it a try.
