For the first week it was perfect for my needs. Good sound, not bulky at all, and just worked. Then the left earbud seemed to drop in quality by a large margin, particularly in lower frequencies. I have attempted all the standard troubleshooting, swapping earbuds, tips, etc, but so far nothing has worked. I don't know if this problem is common with these headphones or if I just got unlucky, but either way they have let me down a bit. Atleast I got them on sale.
