I recommend and finally found what Ive been looking for. The bass seems to be much better than other wireless earbuds I have used, including the Galaxy Buds. I do try to charge them soon as I remember, but when you put them in the case they are charging. I have owned several pair of these and they last several seasons. Next tried size 10, still too big, returned them too. After reading about all their headsets I choose CS540 to be similar to my old one. Can be useful during a variety of activities. They?re stylish and cute! Fits perfect, snug. If you have long feet, they sure do make your feet ?look? long.
