I wasnt expecting it to be like the bigger JBL speakers but it does the job! You can make calls, send and receive messages, get directions, and listen to my favorite music. But it is a good speaker. Ive seen some that make you stop on a dime so that youre tripping over your own feet. But I pretty much have this on my head for a solid 10 hours to put it into perspective. Seem to be durable. The headset is very comfortable - many are not -- and the mike placement is unobtrusive. They are the perfect fit, comfort and weight for me. But due to the fact they are listed as "shower shoes" it will be interesting to see if they hold up as well as your typical tried and true croc sandal styles. Im a 10 and thay are a snug fit .
