This was a pretty fun Karaoke toy. Not every Crocs has the same level of comfort. It still has 75% battery left per the power monitor on my phone. The blades r good. I bought these that I am doing a review for and I like the stem better, NOT MADE OF WOOD, BUT the spiral swab is not tight enough, cotton frays and if you wet them the spiral just seems to disappear and flatten out. For the price/value/ quality equation home listening phones, I have yet to find one that matches these headphones. The opening for the wheel is 2. They are better in some respects than the Boltunes but the steep cost, lack of true water resistance, some latency issues (also present in BT5 AptX ear phones) and a not so effective (real) active noise cancellation mode do not make them a five star product. Made in China, like all of them on Amazon are. Stop thinking about it and just buy it already - you wont regret it!
