"You won't want to take these off - not only do they look good, they're excellent sonically, too." What Hi-Fi Sound & Vision magazine 5-star review at £79.95


Following on from the multi-award winning AKG K450 headphones, the replacement K451 design has already scooped a prestigious What Hi-Fi 5-star award. So good, in fact, are these headphones that What Hi-Fi magazine said there was; "nothing at this price" that could be faulted with them - praise indeed!


High power drive units and a closed-back design give the AKG K451 an intense, powerful sound. Yet, thanks to the innate quality of these headphones, subtle detail is carefully revealed and nuances can clearly be heard. In short, whatever you listen to will be superbly presented and involving.


New to the K451 is a built-in microphone with volume control. Ideal on a pair of mini headphones likely to be used on the move, this enables you to listen to music and take calls on your Apple iPhone effortlessly.


The unique 3D-axis mechanism doesn't just make these headphones easy to fold and carry, it also ensures a perfect fit against your ears. The soft, padded, headband and ear pieces simply add to the long term comfort of these headphones. Although lightweight, the K451s are durable. A detachable cable and folding design helps when transporting the headphones but you'll also discover a solid build quality that's a step or two up from many rivals.

With a spec and sound so complete, the AKG K451 headphones are hard to beat.

Rated 4.7 out of 5 by 76 reviewers.
Rated 5 out of 5 by Outstanding Probably the best phones on the market at this price. Superb sound, lightweight and very comfortable. The extra lead with without the silly volume control sounds much better after finding the volume control problematic, how thoughtful to add this to the package. Great storage case too. Beautifully constructed, simply the best phones I have ever had. Use a good sound source, not a silly iphone to get the best from them. 20 February 2015
Rated 5 out of 5 by Astounding.. Purchased a set from the Guildford branch based on previous reviews...first "run" with an IPod was "well,they do what they say on the tin",so although pleased,was not overwhelmed.However....after a few hours burn in,and listening to my P.C stored hi-res files via a Dacmagic,all I can say is "wow".Get some whilst they are still out there! 05 February 2015
Rated 5 out of 5 by Perfect! Great price for some good quality, comfortable headphones which fold neatly into their carry case. 28 September 2014
Rated 5 out of 5 by Good value for money For the price these are very comfortable to wear, very little sound leakage, and the sound quality is good. Excellent service, quick email confirmation and product arrived in less than 48 hours. 17 September 2014
Rated 5 out of 5 by Quality headphones at an affordable price I bought these headphones after reading numerous positive reviews online. When they arrived, I was not disappointed. The headphones feel solid and the sound quality is immense. The hard case the headphones come with is also a very nice touch, would definitely recommend these to anyone I know. 17 September 2014
Rated 5 out of 5 by Hear songs in a new way The AKGs are very comfortable, sit perfect and are very unobtrusive. The sound... they have a very warm sound across the board. Drums, bass and background sounds come through clearly, a real joy My (great) SM e10s did a similar job, but with them each instrument and vocal came through very loud and 'separate'... a little disjointed at times i.e. I found I had to focus on each part individually sometimes. With the AKGs, you hear EVERY sound come through in a nice rounded way, a nice wide sound that misses nothing out. The drums sound great. The harmonies clear. For BASS, if you listen to drum and bass you'll be in for a treat. They play modern music with a sublime clarity. I'm hearing live music in a different way which I need to get used too... before I like listening to just the band playing, but with these you get the whole concert feel... i.e. the full band and crowd. In all fairness, this probably gives you a better 'being there' experience. For the price... WOW 16 September 2014
Rated 5 out of 5 by Excellent product I bought these headphones to try to help my 92 year old Mum listen to the classical music which she loves. She is extremely deaf and puts them over her two hearing aids. We have found them to be far superior to any previous (more expensive) pairs in terms of sound quality and comfort and she has voted them a great success. 16 September 2014
Rated 5 out of 5 This headphone is just brilliant. Most comfortable and perfect sound. With the discount, it made this headphone worth way more than I could ever bargained for! Top notch sound delivery with excellent packaging. 14 September 2014
