Bluetooth does not work correctly with Siemens Tek Connect headphone device
I hopefully tried the new bluetooth support in OS 3.0, but it does not work with my Siemens Tek Connect headphone device. It syncs as expected, but no sound is heard. I can choose the Tek Connect in the music app and other programs, my headphone (actually my two hearing aids, which are connected wireless with ear to ear communications (e2e) via the Tek Connect necklace device) signals the connection to me (a beep), but nothing is heard. Codec problem?
I tried to do some quick searching, but I couldn't quickly find out whether or not that headset is A2DP capable. Everything I've been reading today when working on my other bluetooth issue says that bluetooth headsets have to support A2DP.
I own Phonak hearing aids with their Bluetooth-capable iCom device which allows my aids to be used as a phone headset and also supports the A2DP stereo bluetooth profile. My iPod Touch 2Gen 32GB is able to play to my hearing aids properly.
One thing I noticed is that the iPod does not allow you to control the volume when using Bluetooth. It expects the headphones to be able to control the volume. Have you used your hearing aids as Bluetooth headphones on any other device? Maybe the device isn't programmed properly to set the volume while in headphones mode. I know my audiologist had to program the volume on each mode separately on my device.
My MacBook Pro is able to play music over Bluetooth to my hearing aids fine. But I have never gotten Windows to work properly sending audio to my hearing aids. Do you have a Mac with Bluetooth? Try to get that working to see if it's your hearing aid device that's causing the trouble or not.
The Tek Connect works great with my Nokia 2600C or the supplied Tek Transmitter. With these I can change the volume at the device, but only in a small range. I have to check the used protocol, may be the A2DP implementation in the Tek does not work correctly.
