Price Paid:  $35.00 from St.Petersburg

Summary:
The price of KPM510 headphones is 35$, but the sound quality in my opinion is equal to two times more expensive Sennheiser HD270. Very neutral sound so one can hear sound as it was recorded in studio. Detalization is also very good for such a chip headphones. Probably the best unit in this price range. No more cheap SONY, Technics etc.

Strengths:
Sound quality in all frequency range, noise isolation. One can even run with these headphones because it is very stable on your head.

Weaknesses:
Not the best ergonomics, a bit to heavy, makes some noise when trying to adgust them on the head.

Similar Products Used:
Technics 400, Philips 900, SONY 380.

Summary:
Overall good headphones, lots of bass. More than I wanted to spend, but worth it. Has good ear cups, so that you do not hear anything from the outside. Long cord so you can walk around, 10+ feet when fully stretched out. Plug is a little loose and easily pulls out of stereo (for the big plug size).

Strengths:
Nice long cord, good comfortable headband,lots of bass, overall good sound quality

Weaknesses:
little heavy, ears get hot if on too long, little expensive
