Excerpt: First of all, I would like to thank Denon for sending me out the AH-C400's to review. These headphones, are the first "premium" range earphones that Denon has released. After being a big fan of the bass quality and quantity of the previous models, like the C710 and the C751 and especially the price...
Summary: Bought these for my son for Christmas last year, good sound and build quality. After 4 months of normal use, not abused in any way, the left speaker gave up. Great service from Amazon as ever, returned and replaced with bose.
Biggest Disappointment in the History of Headphones!!

Summary: What would you expect if you spent £80 on a pair of in ear headphones? You'd expect them to sound amazing right? Not these, I think its safe to say that these are the worst sounding headphones I have ever had the misfortune of listening to! And an RRP of £350! Someone must be having a laugh.
Summary: Bought these headphones late February 2014. Unfortunately, had to return them back after two month due to wire problems. This is despite the fact I took good care of them. It could be manufacturing fault or the material used for the wire is not durable.
Summary: I bough these on 21st Nov 2013 and it's now 20th Feb 2014 - so only 3 months - and although they produce a great sound, the wires seem to have broken, as the sound keeps cutting out. I know wire damage is a common problem with headphophes, but 3 months!!!!! Come on!!!!
