One and a half months in and the seams on the ear cups have already started to split. This isn't an isolated issue as I've found out after trawling the web. Not to mention, Philips' service is terrible...they've had my headphones for close to two months, citing lack of stock as a reason for not getting me a replacement.The headphones sound amazing, just the right amount of bass and great mids and highs. Vocals sound amazing on these cans.If it wasn't for the terrible build , I'd have given them a 5Edit 1(22nd October 2016): I finally got my replacement last week, only to find that the material on the bottom of the headband has started to peel off today... definitely stay away from this headphone! As for me, I'm definitely staying away from Philips products in the future...
