These headphones are amazing. The price is extremely low for the quality of these headphones.
They're extremely comfortable; the most comfortable headphones of any style I've ever worn. Being a huge audiophile, I'm picky about my headphones, and these have beautiful clarity. The range is great as well, the highs are perfect. The mids and lows are right on as well. As for breaking them in, the bass will only get better with time, so that's even better.
Sennheiser PMX60s get LOUD! If you have hardware that can push it, these can bring you to ear drum shattering range and still sound crystal clear. The are only two downsides. These are open headphones, so people around you can definetly hear your music as well. But if you're getting open headphones, that's obvious.Also, the cord is kind of short, but it works for me.
The headphones are stylish, light, and very well put together too. All together, their sound quality, range, loudness, style, comfort, durability, design, and construction are all topnotch; not to mention the very low price.
These are great! Pick them up now!
