Review on Sony WI-SP600N Premium Waterproof Bluetooth Wireless Extra Bass Sports In-Ear 6 Hr Of Playback Headphones/Microphone (Yellow) by Tres Carmon

SONY usually makes great products. However, these headphones had a few issues and turned out to be a total failure. They had no electrical charge at all, none of the adjustable fittings worked, the device didn't come with an AC adapter, and the headphones themselves wouldn't turn on. I've read several other similar reviews online and they seem problematic for SONY (which in turn usually makes reliable products). I recommend NOT buying these as the negative online reviews are similar and the product functionality is completely lacking. Revain did a great job of helping with the return of this product and I only hope SONY can figure out the cause of this product failure to this extent.
