These arrived in about 2 weeks to the USA.
I don't have a ton of headphones, but I haven't heard anything better than these. The smallest rubber piece fits my small ear drums well.
I had to warm up the plastic part of the cord and reshape it to make these go in at the right angle, though. However, that's actually a plus. You can reshape it to fit your ear very easily.
Obviously there are better earbuds out there, but is it really worth it when these already provide such good quality at this price point?
I bought one with a microphone and 2 without a microphone. We use them for monitoring the live stream audio in our church under earmuffs. I use mine to listen to epic soundtrack music at home, too. The mic works fine, but I haven't tested the quality of it.
