Now more comfortable than ever, the AKG K550 MKIII headphones continue their class-leading tradition.

The best made better

With a whole heap of awards to its name, the AKG K550s have become the default choice for over-ear headphones around this price. That hasn’t prevented AKG from improving them, though! With a redesigned headband the MKIII model are more comfortable than ever.

Hear every detail
With decades of experience in the studio few can beat AKG's heritage. With the K550s, AKG have sought to recreate that studio sound with toned down aesthetics. Using their largest 50mm drivers and a closed back design gives these headphones a deep, powerful bass that's also very tightly controlled and realistic. And thanks to what AKG call, 'Real Image Engineering', the K550's sound open, accurate and engaging - even over extended listening periods.

Total comfort
With their large earpieces, the K550's wrap around your ears for total audio immersion. They're also lightweight and with the newly designed headband, very comfortable to wear. Although larger than the average headphone, the closed-back design prevents sound leakage, making them ideal for quality music on the go. The 2D-Axis mechanism with folding ear cups also make them easier to pack in your bag.

Supersize your listening experience, with the AKG K550 MKIII.

Rated 5 out of 5 by from Beautiful sound! I bought these on recommendation from a friend. I had tried them and was very impressed by the full well balanced sound and comfort of the headphones. I use them on my digital organ which has the sound of cathedral instruments. These phones make you think you are in the building which is very exhilarating!

Rated 5 out of 5 by from AKG K550 I bought this for my Father in law for christmas, he thought they were terrific Having had Senhiesers before he was used to high quality headphones. The snug fit and clarity of sound across a wide spectrum of frequencies was amazing. The space in-between instrument and voice was exceptional. At the price I think these take a lot of beating, a great deal.

Rated 4 out of 5 by from Airy sound for closed back phones. Have Y50s, which I thought pretty good, so thought I'd give these a try as I heard they sounded like open-backed phones while being closed-back (which I need for domestic peace). Also they were discounted. They do sound almost as good as open-backed, definitely good value at the price paid (which I'm not allowed to mention). They are pretty detailed so you need a high quality sound source. Slight disadvantages, really only applicable if you want to use them out and about, are 1) they're massive, completely containing your ears and 2) the (detachable) lead is very long - you could get a shorter lead but it uses a mini XLR plug at the headphone end so might be difficult to find.

Rated 4 out of 5 by from Great, despite cost cutting issues by AKG vs MK2 I have owned a pair of AKG K550 MK2 headphones for 4 years, which I also bought from Richer Sounds. Having now just got a pair of these AKG K550 MK3 (at an amazing bargain price of £79.95!) I can now directly compare the two. Overall the build quality of the main body of the headphones is pretty much identical to the MK2, i.e. excellent and beautifully constructed. They have the same comfy memory cushion pads and fit remarkably well onto my bonce, I can use them for hours without ear fatigue or head pain - just like the MK2. However, the noticeable difference, and 'Achilles Heel', of the MK3 in comparison to the MK2 is the cheapened headphone cable. On the MK2 it is a permanently fitted cable and on the MK3 it is removable - this is not a big deal either way, but I personally prefer the permanently fitted cable design. It's probably just down to personal preference. But the main issue I have with the cable on the MK3 headphones is it's thickness - or, rather the lack of it! Directly comparing the two cables of MK2 & MK3 it is obvious the older model's MK2 cable is noticeably chunkier by a good couple of mm. Add to that the additional cost-cutting design difference that AKG have also chosen on this newer model - making half of the jack plug moulded plastic, instead of the all-metal beautiful, tactile design on the MK2. You can't help feeling the MK3 are a step down from the MK2 in terms of attention to detail and quality and value for money. As far as the sound differences between the MK2 & MK3? Well, I can't honestly say I can hear any difference - which was a huge relief; and obviously the most important part of the comparison. If there is any at all my ears cannot hear it. If I'd paid full retail price (6 months ago these would have cost £149) I would be feeling a bit cheated, but at this low price the MK3 are still a brilliant bargain and so much better than dozens of headphones I've tried. Some reviewers claim these either clamp too tight or don't clamp enough to form a seal... I completely disagree both! They are the most comfortable headphones I've ever used. That goes for the MK2 & the MK3.

Rated 1 out of 5 by from Disappointing I really was expecting so much better from these given the reviews. I couldn't give any more than a cursory listen in-store as the required 'real life' set-up (iPhone with DAC) wasn't available, or to approximate. Shame - I now can't take them back as they've been on my ears, so I'm stuck with them. Why don't I rate them? Surprisingly - and disappointingly - tinny, with too much sound upfront and flat dynamics in my experience. Even my £30 Bluetooth cans sound more 3-dimensional (minus the DAC), though the volume on these was good.
