I don't leave reviews often, but these headphones are just so underwhelming. Bluetooth drops in and out. Sounds quality isn't that great (especially for $130). Battery life has dwindled after a few months of use. Just overall unsatisfied with these.

Out of the box I was very excited to receive these headphones. I purchased them with the express purpose of utilizing them in conjunction with my Peloton spin bike. It was difficult to get the Peloton to recognize and then sync with the headset at first; but once I crossed that hurdle everything...

Packaging -Aesthetics

-Sound quality is marginal -Depends on your use Syncing is poor -Jaybird Support is terrible -Charging cord is ridiculously short and the connection is troublesome -Control Location is right up against your head and difficult to reach / use

These headphones are in my opinion the best wireless sport headphones there are. Only problem, and this is the only reason for the missing star, is that they are not grey. They are green. Still it's the sound I wanted

It's early days for me but having tried them out for the first time using the included comply foam tips is that these are very comfortable and securely fitting earbuds with great sound.

Is what it says it is, excellent sound quality.

In the X4, Jaybird solved some of the biggest issues that people complained about in the company's previous models. With that, we really appreciate Jaybird for listening to their customers' feedback. In fact, there's a lot of improvement in these earbuds.

If you were to ask me to suggest a pair that will please most people-no matter their musical tastes or how they intend to use them-I'd recommend Jaybird's X4 wireless sports earphones .

IPX7: can be submerged in one meter of water for 30 minutes; Sound great under most circumstances; MySound companion app allows for EQ adjustment; Ship with Comply foam ear tips; 10-minute quick charge provides an hour of listening

Proprietary charging cable required; Audio becomes muddy at maximum volume; Audio call quality could be better

The X4s are a refresh of the company's older Jaybird X3 wireless headphones. The only significant changes are their improved IPX7 water/sweat proofing, redesigned tips and ‘Speed Cinch' cord management system, which, according to Jaybird, will provide users an even more secure fit.

Solid; comfortable fit; Decent sound for a sports set; Great build quality

Prone to dropouts in busy areas

The new standard.

Decent sound; IPX7 rating; Better fit than previous versions

Kind of uncomfortable; Mids are lacking in clarity; Battery life is good; but still falls just short of the claimed 8 hours

The Jaybird X4 sports headphones have a lot going for them. They're well-designed and sound good, plus they're pretty good at staying nicely in your ears. The app is a nice touch too - allowing you to customize the frequency response to your preferences.
