I have had 5 pairs of these. They are the best ear buds I’ve tried. They outlasted my expensive Beats Pro which are exactly alike but $150. The battery life on them is much better. The sound quality is comparable. I use them for calls at home and work, audiobooks and music when I’m doing things at home. Range is decent enough. Super easy to pair, though they don’t come with instructions. You can find them online though. The only issue I’ve ever had was with one pair I opened, there was only one ear bud inside. I had bought them on sale months prior so I couldn’t return them. The only reason I have so many pairs is because I keep one pair in my work bag and one I use at home, and I have lost a couple of them so had to replace. They last forever. The original ones I bought in 2023 still work great! I lost one at the nail salon, but the other I still have and will occasionally wear it at home while cleaning, and still works like new. They stay on and don’t hurt my ears. I’ve recommend them to many people. I try to get them when they are on sale, and then it’s a great value for the price. I just bought another pair as a backup to store away, and notice they are $2 more than the sale price I usually get. Still worth it. Get them!
