High-quality on-the-go audio utilizing Hi-Definition MicroSpeakers to deliver full range audio, the ergonomic design of the SE210 is ideal for premium on-the-go listening. The SE210 also offers a flexible design for multiple wearing positions.
Though expensive, the more I listen to them, the more I like them. Many have complained about the "lame" bass but this can be improved by finding a good fitting ear tip piece and then the bass emerges very nicely. I use these with the microphone attachment from my 102s and they work well as both an everyday listening and phone answering device.
