Note: this review will be a bit oriented as a comparison with the AD700 considering that it is a reference in its class and that is the only other decent headphones I've owned.

I've used the AKG K240S headphones for a few years now and I remain mystified at all the rave reviews here on Amazon. My experience may be different than some reviews, so I'll explain my approach. I do sound art, composition/production, and I listen for fun.

The look and the build quality of these headphones are great. They have good bass and are easy to drive. Lacking a little in the mids but nothing like the tri-ports.

The AKG K-240 Monitor is the classic studio monitor model, with an impedance of 600 Ohms (sensitivit

Lightweight; rugged; clear-sounding; 55-Ohm impedance compatible with portable players

Somewhat aggressive-sounding at times (curable with EQ); bass exaggeration (curable with EQ)

The first thing I liked/noticed was the appearance of these headphones, they look like retro studio headphones. They sound really clear and you can hear sounds that you can't in other headphones. Also seem kind of too flexible but after a few months of using they haven't came close to breaking.

Great sound on vocals, if only that on/off switch was recessed like the SM58, this would be the perfect mic. It's a pain to turn on/off.

The AKG K240 Studio Monitor headphones are a pair that every musician, recording hobbyist and lover of sound and music owes themelves to try. They produce a soundfield much broader, accurate and detailed than many headphones sold at this price, and are incredibly durable and comfortable to wear.

good comfortable monitoring headphones what can be worn for extended listening

good sound quality; comfortable; reasonable sound isolation

expensive

The look nice, the cord has a dual 3.5mm/.250" jack with a nice gold-plated threaded adapter (best setup I've seen yet for this) and a mini-XLR on the left can only. Comfortable, even on my big head. They don't quite look "pro"--maybe low-end pro.

Good; even; complete sound at very good price

Audiophile Grade "B" at best; appear to be made OK; but not exceptionally well

I originally bought a set of 4 K240df headsets for my studio 10 years ago and through all of the abuse that goes on in a rental studio they are all still working. The thin cable is a lot more durable than it looks.
