Pros: Quality drivers, durable cord, fairly light and comfortable, good stock voicing in the lower midrange, forgiving sound signature
Cons: Upper midrange "dip," untreated earcups are awful, nickel plating on the 3.5mm jack chips off
I've owned this pair of headphones for about 8 years now, and they still don't disappoint, especially now that they have had just the smallest bit of modification, which brought out that wonderful upper treble. They are as follows:
1.) A small circle of SilverStone 4mm acoustic foam in each cup.
2.) Small 1mm perforations in the felt spaced .25cm apart.
Just these two small modifications brought out thunderous bass and forgiving voicing in the midrange, making these headphones great for a wide variety of music and recordings. With the 4mm foam, the driver has just the right amount of clearance. The thick stock felt can either be replaced with a thinner felt or perforated to allow a little more HF to make its way out of the driver.
Durability-wise, everything is very rugged, save for the nickel-plated 3.5mm jack, which seems to lose its coating after a while, causing intermittent connections. A polishing wheel and a little solder was a cheap fix for me. The ear cups are a little hollow-sounding stock, but hey, they're cheap.
These are a must-have, especially for the price, ease of modding, and fairly decent audio quality to begin with. For 15-16 extra bucks, you can have a great set of dynamic headphones with punchy bass, a smooth midrange and laid-back treble.
