I purchased the K240 to take some of the workload off of my old K280 Studio Monitors(that I've happily owned/used for a long long time). Well, the vacation for my K280 didn't last too long as the K240 within the first year started dropping the left channel. I could wriggle a certain portion of the cable and the audio would come back, but it was just a chain reaction of failures after that -1.Right side plastic housing fell apart 2. Left side housing shattered as I was packing it for warranty repair?!? Well I finally had it and invoked the two year factory warranty and I gotta say, AKG took care of me. I shipped it to them and they rebuilt humpty dumpty to like new condition, sadly I rarely use it since I got back due to its' past history. Sound quality, I love the neutral nature of my older K280 and was hoping the K240 would be the same, they are unfortunately not the same animal and the K240 tends to be very bassy. So if you love Bass you'll love the K240. The cable length is around 6'(or so) ,very adequate. Fit, finish and styling is very nice and quite similar to my older K280, I've always liked the Black and Gold scheme of the K240. Depending on how big your ears are this is either going to be an on your ear or around the ear headphone, I found the covered foam ear pads to be very comfortable for long listening and easy to clean. The headband automatically adjusts. The headphone cable is designed to be easily removed and replaced by the user if and when that time comes.
Pros: Looks as good as the classic AKG's. User replaceable audio cable. Standard Mini and Large plug options. Around ear headphones. Self adjusting headbands. If you love bass, these headphones are for you. Quick no hassle factory warranty resolution with my claim.
Cons: AKG is one of my favorite headphone makers but unfortunately the quality of the material(s) used in assembling my K240 really let them down. Left channel died within a year(troubleshot to bad audio cable), plastic voice coil pieces started falling apart on both sides. And I babied these headphones! Very bassy.
