I use these headphones for monitoring and mastering field recordings at home. They are comfortable. They don't exert excessive pressure on the head and the headband is designed to keep them seated right.

Reliability

Pros..brand new ..detachable cord... Cons .. Sound quality ..noise cancellation..

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.

I hunted this model because of these curious DF specification. I was lucky to get one second-head really cheap. I read about harsh mediums and shallow bass, and that striked me at the first time I tried the K240 DF.

The K240S is an odd beast. It's not hi-fi by any means. The bass is big, boomy, and not particularly well-extended. The highs are somewhat recessed and don't convey a whole lot of detail. The sound is akin to a fat black woman shaking her booty on the dance floor. Not a lot of refinement...

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.

These headphones were used by our quality control audio technicians 6 days a week, round the clock, at the major cable station where I worked for years. They stand up well for a long time before they start to fail from so many folks utilizing them.

There are plenty of hand-held dynamic vocal microphones available in the world, and sometimes it seems as though microphone technology has advanced as far as it can. But every once in a while an innovator will make an improvement that advances the technology to a new level.
