Summary: Spent quite a while whittling down my list of on ear headphones to purchase. Finally got to go into Richer Sounds and to try out all 3 AKG on ear headphones. Found the Y40 and Y50 to be of a poorer sound quality in comparison with the 451's.
Summary: Having owned a pair of AKG 430's for ages, I need a new pair suitable for travelling especially on flights Having read reviews the K451 became my first choice and a flight to Ireland proved that these were so much better. Highly impressed by the all round performance.
Worth the asking price, and great for the morning commute.

Summary: I've tried out several 'budget' and 'audiophile' on-ear headphones including the Sony MDR series, Audio Technica ATH-M50, Sennehiser Urbanite and Momentum series as well as Grado SR60, SR80 and SR225i open-back headphones.
Excerpt: Everything is great on the AKG 451. From sound quality, build quality to the surprise that they were compatible with the ps4.
I'm only a little disappointed that I didn't go for the AKG 550. but they will certainly be my next headphone purchase.
Summary: In short: a bit full-on for home use but fantastic travel headphones with good overall sound. Better when broken in and sound varies hugely depending exactly where you place them on your ears. Remote only works for Apple products. Wouldn’t recommend for large heads.
Summary: I do not undestand a lot about headsets but I loved my new AKG K451! Great sound and when they arrived I was using the ones from iPod, which means a great upgrade. The foldable system could be more resistant but the size it gets after folding is really good.

Summary: Wear these 5 hours a day commuting. Good balanced sound quality for music and spoken word and very comfortable. Only downside is your lucky to get 6 months out of the flimsy cables. Use till broke then buy a thicker upgrade, but should have lasted longer for price.
Summary: Great little headphones for travelling around, and a real step up from the earbuds that came with my Sansa Clip. These are *not* the be all and end all of sound reproduction tbh, but the price should tell you that.
