Jaybird is back to its old ways with the release of the Jaybird X4. These are some of the best-wired Bluetooth headphones on the market and should definitely be considered by anyone, but especially if you are a frequent gym-goer. The sound is great and the design is familiar, yet comfortable.

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.

REVIEW – I'm on a mission to find my next favorite pair of Bluetooth earbuds and so far I've been focusing entirely on truly wireless earbuds, but in reality, if I had to pick a pair of Bluetooth earbuds that sound the best and fit the best, the ones I'd pick are not completely wireless.

Good sound quality

If you reside in an area bustling with athletic activity or you often visit the gym, you will realize one thing in common with the runners, weightlifters or strollers. They have headphones on.

I'd always used standard ear buds for running previously but these take things to the next level for me. The sound quality is very good and you can customise it to suit how you like it to sound via the app so you have full control over the EQ/soundstage which was brilliant, took a bit of tweaking...

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

Offering a comfortable fit, outstanding waterproofing. and pleasing, adaptable audio at a reasonable price, the Jaybird X4 wireless sports earphones are a great choice for anyone looking for a new pair of Bluetooth earbuds.

With an IPX7 water-resistance rating and redesigned wing tips, the successor to Jaybird's X3 wireless earbuds are good-sounding sports earphones prepared for wet weather.

Engaging sound; Firm fit; Useful sound-customization

Some hardness on upper mid treble; Slow-to-respond remote

Is what it says it is, excellent sound quality.
