"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 5áby 82 reviewers.
Rated 5 out of 5áby headset for gaming. great choice! I bought these primarily for use with a ps4 so I don't disturb the wife whilst playing. Despite the box saying designed for Apple the mic appears to work fine (sales assistant advised the mic was iphone/ipad only. Better to be surprised in a good way and nice to warn people). 24 March 2015
Rated 5 out of 5áby Great product. Even better price. So I was recommended these headphone by a mate who had a pair. When seeing them on sale I picked up a pair straight away. The headphones are comfy and the sound quality is great for the price. They come in a neat little durable carry case with 2 leads. One with an iPod/iPhone/iPad compatible remote / microphone and another simple lead without the remote. I'm a daily listener of music for my commute into work and I have found these to be ideal. The folding design means that they rotate around the shape of your head and ears too. I'm sure there will be am some audiophiles out there who would have some negative comments to make. But for ú39 you can't go wrong with these. A great make. A great set of headphones. 24 March 2015
Rated 5 out of 5áby Great sound, great value I was looking for a replacement for my worn out Sennheiser 'phones and I found a really excellent one. The headphones are clear with first class sound quality, are very comfortable to wear and great value for money. 24 March 2015
Rated 5 out of 5áby Best compact portable headphones I tried a lot of compact headphones and the K451s were the clear favourites for both comfort and sound quality. The closed back design means they work well at all volume levels, even in noisy surroundings - and the relatively high sensitivity means they go quite loud enough without draining your phone battery. I was able to buy both these and a pair of AKG Y50s for home hi-fi use for less in total than the price of the competing compact headphones I had been considering - avoiding an expensive compromise. 21 March 2015
Rated 5 out of 5áby Perfect all round lovely headphones, rich bass and clear sound, sit comfortably and securely, pack up neatly in a portable zipped hard case which also has space for my iPod - absolutely perfect! 15 March 2015
Rated 5 out of 5áby Great product at a great price Bought these for my daughter to use. Great sound quality and a very handy hard case for when they leave the house! Also got them at a great price at Richer Sounds MK. 14 March 2015
Rated 5 out of 5áby 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 5áby 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
