Sennheiser PMX90

Pros: looks awesome. separation of layers in music are somewhat noticeable.

Cons: extremely thin cable. lack of bass. low volume

Summary: this is not one of those biased reviews against sports neckband type headphone. i love these type of phones and this is one of the sexiest neckband phones i've ever seen but it ends here. the audio quality is mediocre and volume is pathetic. buy it only if you want to use it as a fashion accessory.
