Hello fellow DIYers:
If you're thinking of making your own Bluetooth headphones, don't buy this A2DP Bluetooth dongle from ebay:
http://www.ebay.com/itm/Wireless-Bluetooth-Audio-Music-Receiver-3-5mm-A2DP-For-iPod-iPad-iPhone-MP3-PC-/290920955046?pt=Other_Tablet_eReader_Accessories&hash=item43bc3d7ca6
I took the gamble and lost this time. Though at first glance it does have everything you think you want: A 3.7V 250mAh battery, an OVC3860 Bluetooth chip w/ battery charging and headphone out, and even a PT2308 IC for a headphone amp.
Though easy to pair and it does play music with little noise or interference, the music sounds like crap! clearly somewhere there is a high pass filter that dumps everything below about 500Hz... NO BASS!!! GRR!!
I tried to bypass the headphone amp completely and drive HPs directly from the OVC3860 output, but it still sounded like crap. So either the OVC3860 output section just sucks or some treble boost got enabled inside that chip. I don't have enough info about the OVC3860 to go any further...
Anyways, pretty good little box, smaller than I could ever put together myself, if only it didn't sound like crap!
Anyone else have any experience with the OVC3860 and getting decent audio from it?
