I purchased these in a drop back in November of 2015. The sound quality is great, however manufacturing is horrible. I have had two pairs break now within 6 months from normal wear. The first pair lasted 4 months before breaking, I paid to ship them back for warranty and I got a brand new pair which took over a month to get shipped back to me. This pair lasted 2 weeks before breaking in different spot than the first.
There was a known build issue the first batch of AKG K267s which was addressed with their 2nd release, and now the exact same thing is happening with the K167s.
Even with a huge saving by getting these headphones with a drop, the build quality has made this drop a waste of my time and money.
Would not recommend.
