The Jaybird logo is now part of the paint job instead of imprinted on a cheap metallic sticker, the wing tips just have one big hole now instead of a ton of smaller ones, and the nozzle on the all-gray model is painted blue, and I’m all for it.

Jaybird X3 review: The much-improved Jaybird X3 is a top

The Jaybird X4 dosen't make any drastic changes to the wireless earbud formula that's been working so well for Jaybird. These aren’t the first earbuds to have a sweatproof coating and an IPX7 certification, but it’s a welcome addition to the Jaybird line-up even if it is the company playing catch-up. The Jaybird X3 blew the competition away when they came out, and the true wireless Jaybird Run were good, but not mind-blowing.

Just like the Jaybird X3 and X2 before it, the Jaybird X4 has a little bit of everything and is a great all-around pair of exercise earbuds. The Jaybird series has always had it, but I was never able to make it work for me and just ended up wearing the earbuds dangling under my chin.

To charge them, just pop them on the charging cradle just like the previous version, and plug them into a USB port. Especially when you swap out the silicone ear tips for the memory foam ones (which also help with isolation). One of my big complaints with the previous Jaybird X3 earbuds was that they weren’t waterproof, they only had a sweatproof coating. The thumping bass kicks in the song Generator Playback controls were also intuitive, and I didn’t need to look in the instructions to figure it out.

But the addition of an IPX7 waterproof certification makes these a tangible upgrade to the previous models. You can adjust the volume by tapping the plus or minus buttons and skip between tracks by holding them down. These are the first time I was able to wear them comfortably behind my head, without needing to worry about them slipping out of my ears. It’s almost exactly the same as on the Jaybird X3, which isn’t bad considering how slim that control module was as well.
