Average Reviews:
(More customer reviews)I recently purchased a Sony DR-BT50 bluetooth headset and a K-Mate BTT004 bluetooth dongle (oh, by the way, that's what the "Agptek Driverless Sliding Bluetooth USB dongle" really is called). I have a Dell Studio 1536 AMDX2 64bit with Windows Vista Home Premium service pack 2. I specifically bought the headset and dongle because of favorable reviews on Amazon.com.
I knew I might run into problems when I read the packaging. "BTT004 is a USB MV Dongle of automatic driving. Just plug BTT004 into USB port of PC, no need additional softare installed in the PC." Ugh... chinglish!
1) I can pair the headset to my phone. The audio sounds great.
2) I can pair the headset and dongle on my spare windows XP machine. The audio sounds great.
3) I can pair the headset and dongle on my Dell Studio 1536... however the audio sounds horrendous with a constant static crackles and pops, as if someone was crumpling up paper. When there is no sound, the headset is quite. Start playing a song on Itunes and the crackles get louder and quieter with the music.
Does the problem lie with my Dell studio 1536's audio card. Perhaps? But this dongle uses Microsoft's generic usb audio driver (usbaudio.sys). I have a feeling the problem is the audio driver. I found a potential fix online where people replace Vista's usbaudio.sys with window xp's version. This advice was nearly 2 years old and when I tried it, it didn't work for me. I lost audio to the headset. I put everything back to where it was afterwards.
In conclusion: I think I may shop around for a dongle that has it's own driver disk and doesn't rely on microsoft's generic usb audio device drivers.
Agptek and K-Mate have useless Chinese websites with no driver updates or support.
Will this dongle work for you? It worked on 50% of my computers and 100% of my cell phones. So perhaps. I, however, can not recommend this item at this time. Spend the cash for a better dongle by a brand name company.
