'A hugely capable pair of closed-back headphones that just don't sound closed. Rousingly musical and with no obvious deficiencies.' What Hi-Fi Sound & Vision magazine.

Group test winners

Fresh from their group test win where the AKG K550 headphones triumphed over nine rivals, these headphones come with the highly coveted 5-star What Hi-Fi award.

Reference sound quality
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 large 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 broad 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 fold-flat ear cups also make them easier to pack in your bag.

If size doesn't matter but sound does, then the AKG K550 headphones are simply the best in their class - just ask What Hi-Fi!

Includes a 2-year limited guarantee.

Noise Cancelling

Headphone sensitivity is measured in dB. The lower the figure, the more powerful the driving amplifier needs to be. Headphones for use on portables need to be of higher sensitivity than home hi-fi ones.
Impedance is measured in ohms and should be matched carefully to the driving amplifier for the best sound quality and reliability.
Frequency Response
Frequency response is measured in Hz and gives an indication of how low and how high the headphones will go.

Closed back headphones block out more background noise than open back ones. They also leak less sound

Rated 5 out of 5 by from huge difference Superb sound quality. Detailed. No need to use any equaliser settings. I am using mainly with a galaxy s7 and flac files. Despite looking bulky they fit well and headband exerts little pressure.

Rated 4 out of 5 by from Small Heads Beware I should have tried these in-store before I bought them, having done so I may not have purchased them. My head is simply too small, even with the headphones at there smallest they are too loose and sit too low on the head - the clamping force is barely enough to keep them dropping off with general movement. I reckon modification with a thicker pad to the overhead strap may overcome some fit issues. Sound wise they are excellent, easily driven with phone, ipod, portable amp and computer. Personally there size and cable length makes them home or studio only headphones. Isolation could be better even with the large ear cups however I feel this is down to the fit.

Rated 5 out of 5 by from Great buy at a great price Having recently renewed my love affair with vinyl by purchasing the lovely TEAC turntable from Richer Sounds I had to complete my journey back in time by getting these headphones. i would have liked to have gone crazy and spent £400+ on the Shure but I soon got over that. No need to spend Megabucks when you can steal this quality for just over a ton. Super comfy and great sound with more than adequate 3 metre cable. If you want portability get the excellent, foldup smaller AKGs for 50 quid. When you're in your favourite chair with your eyes shut then get these. As usual top service and price from Richer Sounds. I've never bothered looking anywhere else for years now.

Rated 5 out of 5 by from AKG K550 Mk2 I bought the AKG K550 Mk2 headphones as they are equiped with a 50mm driver aimed more towards the treble high frequency levels rather than the low frequency base levels. If you are looking for lots of base I would look at other headphones, but if you prefer the treble sound for live music then these are the headphones for you. The large ear cups are very comfortable and spacious sounding. Over ear headphone pads do not hurt my ears unlike on ear headphones that can be uncomfortable. I am buying a DENON DM40 DAB mini Hi - Fi just so i can plug these excellent headphones in and lay back and relax. They sound great when plugged into a mobile phone but sound amazing when plugged into a proper sound system. Great sounding headphones not only for music but also great for listening to tv and even playing ps4 games. The AKG K550Mk2 are built to a very high standard with a 3 metre high quality thick studio cable and supplied with a 3.5mm and 6.33mm standard plug adaptor .

Rated 5 out of 5 by from Absolutely brilliant product These headphones do exactly what it says on the box. Absolutely brilliant, sound is spot on, noise cancelling works great and no one else is disturbed while I'm listening to some fantastic music. Would recommend them to everyone.

Rated 5 out of 5 by from Great sound I work late shifts & these headphones are ideal when listening to music & TV late at night so I don't disturb my neighbours.Although quite large they are not heavy and are very comfortable. I was told in store that they would take about 20 hours of use to settle & this proved to be the case - the sound quality is excellent. 3M cable length is very useful.

Rated 4 out of 5 by from Love at first sight Love at first sight when I opened the box of these headphones. I already had AKG K701's for a few years. Basically I actually love the AKG K550mkii. I haven't burned them in yet but they seem ok. My older open back K701's are burned in well and sound more like true reference spacious audiophile sound though... The K550's are so gorgeous though - and exellent value at the £100 mark, that I bought three pairs in the end so unless the house burns down I've got good headphones for life! Richer Sounds company seem solid British company and delivery is prompt.
