Summary: This is my second pair of AKG K451's. My first pair lasted a good number of years without any degradation of bass or overall sound quality, so to buy another pair was a no-brainer. The build quality of the HEADPHONES THEMSELVES is really second-to-none. They can effortlessly handle a very low bass frequency with little, to no distortion (depending on the source), which considering their compact size is extremely impressive!
Summary: I have used the more inexpensive Sennheiser, Shure and Klipsch range of head/earphones over the years. The AKG K451's do have a moderate amount of bass, but certainly not the treble quality and overall clarity of the previous head/earphones I have used. Regarding soundstage, my Klipsch S4 IEM's have far more! Returned.

Summary: I bought these as they were reccomended on what Hi-Fi. They were made out to be worth so much more than the price. Buy in my opinion clarity was lacking and bass sounded "muddy". Build quality seems good and they are comfortable but they sit on ear which feels "cheap". I was able to return them thanks to amazon. As I couldn't see the improvement over my £15 in ears. This is the only reason I could give an extra star is Amazon's customer services which is great.
Summary: Very disappointed with the quality of the audio overall for what is a five star What HiFi Reviewed product. Although there's plenty of bass, mid-range and reasonable detail, but the top end sounded very muddy and even muffled spoiling a wide range of music that I tried - so much so that I thought there must be a fault - but another pair were just as bad. Definitely one to audition before buying if you can.
Summary: One word "overrated". Needed to replace my broken Audio Technica ATH-ES55 and was steered towards these AKG because of their price and positive reviews. In terms of portable on ears they are a good package but the sound just isn't good enough, the bass is too overpowering with mids and treble sounding a little dull, I've now sent them back and managed to source another pair of ES55 for £49 from Richer sounds and my ears are now being treated to far more of what the...
Summary: I realise that this is an entirely subjective affair, and that many will think I'm plain silly in my opinion, but for me these phones are a case of added bass coming at the expense of mid-range and treble. As a mostly classical listener, I found the higher ranges somewhat lacking in clarity and crispness. I found this to be the case even with baroque music performed on period instruments where you expect a lightness of sound.
Summary: I bought these on the basis of the reviews here and the Which Best Buy recommendation. To be quite honest I am not sure why so many people think these are great. The build quality isn't particularly special, especially the inline remote and the leads feel cheap and the inline remote doesn't work on mine anyway so I guess I'll just have to use the cable that doesn't have it.
Summary: Maybe my expectations were to high but I'm really disappointed with the sound quality of this item. I use Sound magic E10 in ear earphones to listen to my mp3 player which gives a really good sound. I wanted some on ear headphones as they're easier to wear when you're out and about and you need to keep taking them on and off. As these were £125 until quite recently and were WhatHifi award winners I thought they would be a step up. Far from it. The E10's are far superior.
