I got 5 pairs in the last drop, which came in time for Xmas gifting. Got to keep in mind the price point and you won't be disappointed. It's been three-four months, they still working and not broken, Guess I'm one of the lucky ones.
For me on a PC with Audioquest Dragonfly, I find the bass is pretty emphasized and the highs almost missing. They are fine for out and about using my phone as a music player. If you are looking for hi-fi, then keep on looking.
