This would be a 5 star review if Jaybird and/or amazon would honor the warranty to fix this, I hope a one off, defective unit.

I speculate that having those exposed power connectors on a supposedly sweatproof device is probably what killed the unit

I don't know if the unit was faulty or if after 10 minutes of trying to get the earphones charging module seated in the cradle, I was successful or not, but I never got the yellow light to stay on nor would they charge

but they obviously encountered so many failed units that they had to qualify the lifetime of the product as just 2 years

Next day, the unit is completely dead again.

I ordered a pair of Westone Bluetooth headphones and have my happy life back.-You will find many poor reviews concerning Jaybird X3 charging system.-They are replacing failed units with the same poor charging design units, OVER & OVER

I never get them wet (outside of my workout sweat) so I don't abuse them in any way and expect them to last but all 3 units have disappointed in reliability, especially the X3s

My first unit died in less than 3 months

Other online reviews don't match my experience, so it is possible I had a faulty unit.

Unfortunately, with this third warranty replacement for a new X3, Jaybird stated that they will no longer replace any future faulty units for me.

In addition, they require the use of a TINY proprietary charging unit

On those "cheap" units, you plug the micro USB directly into the device without a dock

Shame as I really liked the original bluebuds which never had a problem.

n’t lose anymore

took me less than 30 min t discover how it all works and charges, super user friendly application

n’t recommend to anyone.
