Summary: These headphones are terrible. Two pairs from different retailers have the same problem: the left driver is muffled. It produces a significantly quieter and lower-quality sound than the right driver. It's particularly noticeable at lower frequencies. I've tried both cables (rotated in) and three different devices, as well as multiple audio files (including ones for testing headphones). I also switched ears and switched between both drivers with the same ear.
Summary: These headphones may not be for everyone but if you're looking for a sleek package that is easily portable, not too bulky, and packs a decent sound for a great price, these AKGs get the job done. Do they produce the same sound as comparable open air headphones around the same price range or slightly higher?....
Pros: Solid mids and highs, great portability, tangle free cord, no sound leakage
Cons: Sound not as good as open air cans, feel a bit tight after a few hours of wear
Summary: I recently bought the AKG K-451 headphones this fall to use with my laptop and Iphone. When I first began using them, they sounded a bit 'stiff'' and dull. The sound was strong, but something was missing. So, I continued to use them daily over a period of several weeks, listening to Jazz, New Age, Dance, Rock, Funk, Soul, Acoustic...pretty much anything I could find to measure their sound quality. Obviously, the higher the bit rate, the better the results.
Pros: Very comfortable, spacious, solid sound, clear detail
Summary: Lets just say there louder and much clearer and cheaper than the Bose OE2i headphones. I had 4 days now to compare the 2 set of headphones and I have to be honest the AKG K451 are a better sounding and had more to offer. My only issue is the build quality of the cords that comes with the AKG K451 might not last as long as the cord that comes with the Bose OE2i headphones.
Summary: I bought these about 3 weeks ago as a to-go pair with my QLS QA350. I should preface by saying I'm not particularly experienced with audiophile gear. These would be my first considered purchase in the reasonable-quality area after becoming fed up with lousy fidelity from mainstream mp3 crapola.
I bought the QLS and the AKG's simultaneously, so I'm not entirely sure which exactly the qualities emanate from, but I'll hazard a guess.
First things first.
Summary: I joined head-fi specificaly to post this review....
First - my credentials as a headphone user (as far as they go). I've been into hi-fi for 3 decades, and consider myself a reasonably discerning and critical listener. I'm currently using some byerdanmic p50t's, a pair of koss prota pros :-D and some sound magic e10 in-ears for the bus :-(.
Disclaimer - I've also posted more or less the same review below on the What Hi-Fi site.
Pros: Nice packaging. The remote control seems to work
Summary: I've had these headphones for around a month now and they were great for the price I got them (£50) The sound quality is great, with more bass than I find in ear headphones can provide. The are nice and comfortable and very light on your head. The wire is detachable from the headphone and they come with a spare wire, so if the wire were to break you could replace it instead of buying new headphones. They also come with a carry case.
Summary: Previously has a pair of Sennheiser PX200 which were pretty good, but these are superb for the money. Detailed, good separation and tight punchy bass. Comfortable, well made (cable is a bit thin, but no real issue) and even look good. I would buy again if these ever break. Literally the only thing that I can fault at all is that even though they are closed backs, if you're wearing them outside and it's windy you can really hear it passing through the heaphones which...
Summary: Picked up this headset for under £50 and I'm totally delighted. I use them with various iThings and they are easily the best sounding portable headphones I've ever heard. There is detail, separation, richness and clarity across the audio spectrum, so much that I'm hearing stuff I've never heard before in music that is very familiar to me, and I'm quite an active listener. There is also an indefinable other quality to the sound which I can only describe as 'texture'.
