TFZ X1 Bluetooth Wireless Waterproof In-Ear Monitor (IEM) Earphone

Our Thoughts

This one took us by surprise. It's incredible that TFZ has built a wireless *waterproof* IEM with excellent sound clarity all for sub $100. It single-handled blows away the competition for a portable earphone that is suited for active use. Too many sport earphones sound like a bad portable speaker, this is not one of them.
