I use the Jabra A125s in conjunction with an Ipod classic, Jabra 8010 stereo headphones, and a Motorola Razr phone while I bicycle.The headphones will pair with two devices at the same time, so I pair them with the Jabra A125 and the phone. The intent is that I can listen to music, but if a phone call comes in, I hear a ringtone and can answer the call by pressing the answer button on the headset. That didn't work until I downloaded new firmware for the headset, now it works fine.The sound quality is great. The communication range from the A125 to the headphones can be up to 20 feet or so without obstacles, but reception is surprisingly sensitive to orientation or placement when on my bike. I have to put the ipod in my rear jersey pocket with the A125 closest to the right side, or else the sound cuts out a lot. I haven't had any problems with the A125 disconnecting from the ipod, even though I use a silicon glove for the ipod.One downside of the A125 is that there is no way to determine the battery level until it starts to fail. And the confirmation you get turning it on is the same as when you turn it off, so if you don't know the state you started in, you don't always know what it's changing to.It is convenient that the LED color shows you when it charging and when charging is complete. For the price, it works very well.
