AKG K240 MKII Semi-Open Circumaural Headphones

An update to an industry standard, AKG K240 MKII headphones deliver lower impedance, higher sensitivity and accurate frequency response from 15 Hz to 25 kHz.

Overview

The K240MKII is an updated version of AKG's most successful headphones with Varimotion technology and XXL transducers. The K240MKII's semi-open ear cups have around-the-ear coupling to deliver solid bass, accurate mids and crystal-clear highs.

Thanks to its lower impedance and improved sensitivity, it can be used with low-output audio sources to deliver its incredible sound.

The detachable OFC cable has gold-plated plugs for optimum audio quality and exceptional ease of service.

Features:

- Professional hi-fi stereo studio headphones
- Semi-open, circumaural design
- Self-adjusting headband for optimum fit
- Patented Varimotion speakers
- Leatherette ear pads and velvet ear pads
- Single-sided, detachable 3 m cable and additional 5 m coiled cable

Varimotion: The basis of superior audio performance

The heart of any headphone is the diaphragm. Made of extremely thin foil, the diaphragm is required by transducer designers to perform incredible, almost artistic feats. The rim of the diaphragm must vibrate elastically while the center portion should move like a piston. AKG achieved just that by designing the Varimotion system.

The "sound zone" in the center is thicker than the rim and therefore moves like a piston with no partial oscillations. The result is an absolutely realistic sound, with a better sonic perspective and an airier high end. The rim, or "movement zone", is thinner and vibrates more easily, providing a powerful, punchy bass range.

"The Best headphones for anything...studio...audiophiles...home users...outdoor use"

Overall:

(see rating details)

I've tried many, many, many headphones from $50 to $600. Just to name a few - AKG K702, K701, K271, K171, Koss PRO4AAT, MV-1, Beyerdynamics DT-770, ..... Nevertheless I like these most. Why? Because they're good for everything. Not excellent in every area, but well balanced. For instance K702 has crisper, little more detailed sound and wider sound stage, but zero isolation, making it unusable even in quiet outdoors or during recording. Same with K701. The K271 sound is concentrated on mids, they may be a little more detailed, however the sound stage is much more narrow (price for better isolation). Koss PRO4AAT are very flat, however very uncomfortable to wear for longer periods. DT-770 as well as some other BD are not very good in trebles, the sound is somewhat laser-shaped. These K240 are: - semi-opened - at least some isolation and some sound stage - very comfortable - unlike the AATs - easy to drive - 55Ohm! - performs well even in outdoor use (sometimes even better than closed headphones, because the isolation is not that strong - less bass gain from outside) - not cheap, but well-priced :-) - durable - they withstand almost anything (even rain) - more quiet when recording than K70x . While there may be some leakage to microphone, these headphones proved themselves excellent when recording wind instruments - comes with two cords and two cushions, excellent

Sound
Simply excellent. Wide soundstage, not that much as K702, but great. Trebles… read more are little higher, but nothing disturbing. Bass is fine, even in subsonic level and middles are well-blended between these.

Features
5m coiled/3m straight cable and changeable cushion is excellent thing. Most of the time I use 5m cable with soft cushion.

Ease of Use
Once you put them on your head and hit the play (or rec) button, you can enjoy nothing but natural sound. So yes, just put them on and press play.

Quality
They are durable even if they don't look like durable. The construction is pretty sturdy and well-made. And most importantly - Made in Austria

Value
Yes definitely! It's worth every cent you've put into this. I'd say don't waste money on K702 or any other headphones, but that's just my opinion.

Manufacturer Support
no need

The Wow Factor
