NOT RECOMMENDED. Tonight I actually saw the watch start to drop in percentage while it was on the charger. I had a desk job and enjoyed my heels and had a closet full to wear for every day of the week for about 4 months. Easy assemble, lightweight, looks good on my Subaru crosstrek And Im questioning drilling 6-8mm holes into studs to fit the anchors. I?d like to see amazon do better describing how fantastic we?ll built great sound exemplary company Klipsch is. I bought these because I wasnt ready to spend $125 on the OBTB version. These are comfortable and have the versatility of having both Bluetooth and wired connection to my phone. OMG - I?m BEYOND thrilled with these. I personally am quite big chested.
