I ordered these heels to wear for my wedding, and though I had brought a pair of flip flops for back-ups during the reception, I ended up wearing them for most of the reception. The issue is the volume jumps up massively at around 14. The base holds the remote very well. Hope KEEN could get back the quality ! jump the next song when the phone listens to songs, answer the phone, And charge if there is no electricity, Which is easy to use it. Service is great (the second mouse was a free replacement), but the product quality is quite terrible. These are so surprisingly comfortable. Although comfortable soles as usual, These were just too narrow so I sent them back. I feed my family with this headset and trust me making six figures + a year I?ve probably have spent over 5K in headsets before I found this one. Vocals are greatly improved over TV speakers.
