I use these headphones for listening to my PSPgo while riding my bike. There is no wire, obviously, so I do not get caught on things. The sound quality is more than adequate (I rip music at 198 kbps. The bitrate is the limiting factor on sound quality here, not the headphones), and they get loud enough that you can wear them around your neck and still hear them CLEARLY (as will the person next to you. I do not recommend you listen to anything embarrassing in this manner).They *will* cut out occasionally, but it is quite infrequent, and only for a moment or two. On average, I get one cutout a day, and I listen to them for the entirety of my 20 minute bike ride (both ways).As was mentioned in another review, the antenna is built into the right side speaker. There is a dramatic difference in signal fidelity between leaving your audio source (my PSPgo) in your left or right pocket. As long as the signal source is on your right side, you should be peachy, even outdoors. Indoors, the signal appears to be magically enhanced, and it matters much less if you keep your device in the incorrect pocket.My greatest source of displeasure with these is that they charge with an AC adapter, and not by anything that I can plug into a USB port. I personally have many more open USB ports than wall outlets, but it is only a minor inconvenience.Oh yes, and the joints where the headphones fold are quite solid-feeling, and they do not cause any problems for the wearability of the item.
