Summary: short terms:
compact, loud, nice sounding, cheap ultraportables.
AKG in the house ( fun, smooth, bassy, bright-warm & clear presentation )
cool for mainstream song including R&B, but not so for bass heavy genres
you can describe it as a lesser-hifi than K420 for half of its price
Pros: fun full sounding AKG sound signature, nice designed cup
Summary: I got this as an impulse buy while I was living in Seoul. I already own the Audio Technica EM7 (which are amazing, BTW) but they were a mess when I had to take them on and off around Campus (although they are great for the street). Boy was I surprised.
Pros: Great sound, extremely portable, good construction
Summary: This was the first AKG product I purchased. I decided to try a more affordable model to get an impression of the AKG sound. I bought this for $28 on a clearance sale, a major discount from the MSRP of $99.
Pros: Compact, impressive mids and bass for the price
Summary: After reading the reviews i was expected much worse in the way of comfort. The clamping force was a tad strong but the flexible metal band was easy enough to bend for a lighter clamping force.
Pros: Detailed, Excellent Imaging and Sense of Forward Depth, Can Be Comfortable With Basic Adjustment
Cons: Apparently uncomfortable out of the box, Limited bass below 40-50hz. Slightly peaked at the very top Of their range (could be attenuated effectively)
