I have had difficulties in the past with Bluetooth pairing so was anxious when buying these. Works perfectly on my Schwinn Sand-Cruiser. When they started to feel a little loose, I put them in the washing machine, and when I pulled them out, they were good as new. I dont know how many times I have forgotten my keys but with this (and somewhere to actually put letters), by the front door, it makes a forgetful brain remember to leave with keys! Basically within the first two minutes I couldn?t wait to take them off. This is very easy to set up with the phone and easy to use. Fits nice and is what a womans slipper should look like. I had used a G203 for quite a while so I got really accustomed to its shaped. Pros:Comes with a 4-channel (mic and speaker) to 3-channel splitter (mic speaker) 3. They look enough like regular shoes that people dont notice if you have to run into a gas station or convenience store while wearing them, and no holes means theyre waterproof so you can wear them outside without getting your socks wet, and clean them easily with a quick rinse if they get dirty.
