Dependable, great battery life, comfortable even to sleep. Great for smaller ears. I have 4 of these in different locations and all 4 pairs work well and as expected. Immediate pairing with iPhone 13 after first time. Notification voice in Chinese which is suboptimal and hopefully will be changed. I have very expensive buds (Bose) and I find I use these almost exclusively. Just know there is no noise cancelling properties with these ones.
