Summary: disclaimer: I'm still pretty new to this whole 'audiophile' thing so my impressions probably are not the most accurate. i don't own any so called 'high end' audio gear so all my comparisons will be done with respect to sounds in real life, against what instruments actually sound like in a band or when singing. all tracks used are either 320kbps mp3 or lossless CD rips on an iphone 4
build: build wise, i have no issues at all.
Pros: compact size, minimal microphonics, great sound
Summary: I was looking for a set of earphones for iPOD listening during my daily commutes. I compared the UM1s with similarly priced earphones and found these to have the best bass response and overall quality. After about 3 months of daily listening, I still craved more bass and upgraded to the UM2s. Most of my friends wouldn't know the difference, but if you're a bass player, you would.
Summary: It was midnight and I was surfing ebay for fun like I normally do and saw these headphones on sale from a reputable USA seller. The deal was ending in 20minutes and there was only 1 pair left... 40 seconds of thought, debate, and action take place and next think I know ive spend $60 on headphones I dont need.
