I picked these up when they first came out and payed a ton for them. I have never once regretted the decision. Originally I was going to use these with my PPC-6700 when the A2DP hack was released. Unfortunately, stereo Bluetooth on the Apache never panned out, so I mostly used them with the transmitter to wirelessly listen to my iPod (and Zune) and loved it. I work in a noisy environment with a ton of electrical equipment and was constantly astounded by the range I could get out of these things. Of course, YMMV when you pair these with a phone, but the stock transmitter is powerful.Later, I bought a PPC-6800 (Mogul/Titan) and these pair nicely with the handset and provide full A2DP support with pocket media player. Call quality is poor, but I blame the buggy BT stack on the phone for that. On every other handset I've used it was pretty good.
