Muddy, claustrophobic, rip-off lead, useless on public transport,
This review is from: AKG K451 High-Performance Foldable Portable Mini Soft Cushioned Headphones with In-Line Volume Remote and Microphone Compatible with iOS Apple Devices - Black (Electronics)
I bought these sight unseen based on the reviews and they were cheap in the Superfi sale. I wish I hadn't. They are open backed which means all your noise spills out and makes people tap you on the shoulder, never good in the morning commute or even worse on a flight. Next issue is that outside noise comes in.
Then the sound quality - it is rotten, the bass is too heavy, the mid range is muddy and undefined, there are few highs, the whole thing sounds dull. People talk about running them in, well I tried this for 48 hours running iTunes in the background thru the phones, they sounded no better for it, they are nasty.
Another big problem is that the detachable mini-jack lead - of which there are two supplied - has a proprietary interface where it meets the headphones, meaning you have to use one of AKG's leads, which cost a tenner for one that "lasted a week" from a pattern supplier on Amazon or almost £30 from AKG, this is a joke.
What to buy instead: The best phones I have had for years are Goldring NS1000 noise cancelling, closed back, they suppress plane and train noise really well, detachable standard lead, nice carry case, bouncy rock phones, a bit bass heavy even so but they are streets ahead of these horrible AKG's.
