Reasons Why You Should Buy Them

  • Jaybird X4 are neutral-sounding earbuds with decent clarity and respectful bass to listen to podcasts or pop/hip hop music
  • Fully waterproof due to IPX7-rated, earbuds can be fully submerged in water for up to 30 minutes and 1 meter
  • These Bluetooth sports earbuds come with Speed Cinch (a new cord management system) that makes it easy to adjust the cord length
  • With the well-designed companion app, you can customize the sound and save profiles for a better listening experience
  • The slim, lightweight inline remote is barely noticeable, especially when you're running
  • Wing tips securely keep wireless workout headphones in place without worrying that they fall out during running or gym sessions
  • With the ear tips and fins in the ear, switch between over-the-ear and under-the-ear positions simply by turning the bud
  • Double-click the "play/pause" button to connect to Siri or Google Assistant
  • Fast charging technology provides up to 1 hour of play time from a charge of 10 minutes
  • Come with a protective carrying pouch to prevent earbuds from scratches and daily wear

Reasons Why You Should Avoid Them

  • Thick silicone hooks could make the Jaybird X4 less stable and uncomfortable for some users
  • They have a proprietary charging cable, in case you lose it, you'll have to call Jaybird's support service to get a new one
  • The average battery life is only 8 hours, a little less than our expectation
  • There is a slight delay between pressing the center button and music playing/pausing
  • Due to noticeable latency, these running headphones are not suitable for viewing video or game content
  • The bass and treble are good, as long as you get a good fit, otherwise they sound thinner than they should
  • Call quality is below average, and people at the other end often hear the thumping and rustling of the cable

Highlights

  • Battery provides up to 8 hours of playtime on a single charge
  • 10 minutes of charging provides a full hour of music playback
  • Sweat and waterproof design, so you can easily wear earbuds while exercising
  • A comfortable, versatile design of wireless workout earbuds for a safe, sport-specific fit
  • Jaybird app to customize sound equalizer and save personal settings
  • Manage calls, and control/listen music at the touch of a button
  • Convenient one-touch access to Siri or Google Assistant on your phone
  • Speed cinch system allows quick and easy adjustability of the cord
