Decent value for the money, but the straps are almost worthless - do NOT use them. Bluetooth connection is as good as any $300-$400 level headphone. *****I did send the slippers back and get a size 10. After using it for a few days I discovered that the right and left shoe were not equal size. I bought these for a holiday in Thailand as I knew we would be doing a lot of walking and I was having trouble with my knee and hip so needed something comfortable. My one wish is that the little alarms could be thinner to fit better inside wallets or on the back of phone cases, but honestly it doesnt decrease the functionality at all. The only problem with the case is that it hits the volume switch and often mutes it. don?t bother unless you get free returns. It is a firmer wedge with a narrower foot bed. Super cute and cozy slippers.
