I had major Q.C. Problems with the four products I purchased from them. Returned one headphone for issues and I had to fight with them. They just sent me another headphone. The audio players were junk too. This was one of their top models back in 2014. After the warranty, all kinds of issues. Just a big piece of expensive JUNK!! Phones 560's lost a speaker on one side. Audio players: one was their mini-players and the other HM 801. This was the biggest piece of junk ever made. I think I have the model numbers right. I finally threw the players...

I really like the t-90;  I have had them for about two months and really enjoy the brightness. I also have the T70p and the t-5p second gen. I like the t70p better than anything so far. The t 90 are fun to listen too-there's treble and brightness-but I like it. The sound stage is good-again, I like the t-70p.
