I bought this because I've been wondering about these types of earbuds for a while now. The entire package is small and light. I love the portability of it. The carry case fits comfortably in my jacket pocket and provides 3 extra charges. The buds are a secure fit with the included silicon tips and don’t fall out even with vigorous head movement. I’ve had too many earbuds fall out on me to know that this is something to look out for. These buds seem to have solved that issue for me. They are also very comfortable and feel fine even after a 1 hr call. The earbuds produce a solid bass and clear mids and highs. It seemed to sound warmer with the ANC on, however. I like my music balanced with a hint of bass and these seem to fit the bill. The ANC is good but it doesn’t completely cut out ambient noise. The buds had good battery life. It lasts about 4 hours with the ANC on and around 7 hrs with the ANC off. Overall, I found the TaoTronics earbuds of great quality at a reasonable price. A brilliant buy by any measure.
