First, let me state that I received no benefit for this review, nor would I accept one if it were offered. I wanted to state that I was really surprised by the quality of this... neckphone?It seems to hold a charge fine. I walk about an hour almost every day and it has never died during that time. I recharge it every night.The sound is surprisingly good, considering the extremely low cost. You're not going to confuse this with a Bose speaker, but get this -- several of the Bose neckphone CASES cost more than this did. Wow!And get this for a bonus. I bought a new XBOX controller a few weeks ago that needs what I believe is a Type-C USB cable, so I had one added to my Amazon cart. Boy was I surprised that this unit actually included that type of cable for charging, so I removed that from my cart. That saved me $13, so when I consider that this speaker cost me about $18, with the cable savings it ended up costing me $5. Can't beat that.One tip. I did not find that it moved around on my head too much, but in these days of high heat and humidity, I will admit that it felt uncomfortable sticking to the back of my neck. My wife to the rescue! She bought some wrist sweat bands that I slid on. Presto, problem solved!
