Overview: The Jaybird X4 in-ear wireless sport headphones are
fully weatherproof with an IPX7 rating, and are designed to
withstand the rigors of your workout. Not only are the headphones waterproof and
sweat-proof, but they will stay in place, no matter what your level of activity.
The X4 comes with four pairs of silicone and memory foam ear tips, secure-fit ear
fins, a cord cinch, and a shirt clip. The headphones and accessories can be
stored in the supplied water-resistant pouch.
Ear Tips: The Jaybird X4 in-ear headphones include both silicone
and Comply memory foam ear tips in two sizes each. Three sizes of ergonomic
Secure-Fit ear fins are available for greater comfort and fit.
Over/Under Ear: The X4s can be worn in different ways depending upon your
intended use. If you plan to wear them during rigorous sports, running, or biking, it is
recommended that you choose the over-ear sport fit. The included cord cinch
can be used to take up the slack of the connecting cable and get a snug fit
around the back of the head. If using the X4s for casual listening, the
under-ear casual fit is recommended. The included shirt clip lets you attach the
cord to the collar of your shirt.
Bluetooth: The X4s are equipped with Bluetooth version 4.1
with Multipoint, allowing you to
listen to music or take phone calls wirelessly from your smartphone. The
headphones have an effective range of up to 33 feet, and are compatible with the
following codecs: AAC and SBC, and profiles: HFP, HSP, A2DP, AVRCP,
and SPP. Multipoint allows you to be connected to two devices simultaneously.
The earphones can remember up to 8 paired Bluetooth devices.
Smartwatch Compatibility: The Jaybird X4 has the ability to
pair to your favorite smartwatch. If your smartwatch has music onboard, you can
leave your phone at home and listen to music from the smartwatch. The X4 is
compatible with select Apple WatchOS, Samsung, Android Wear, and Garmin watches.
MySound App: The Jaybird MySound app, available from the App Store and Google
Play, lets you customize your EQ settings to your listening tastes. You can
sample the EQ presets of numerous athletes and artists, and download the ones
you like to your headphones. You can even create your own sound profile and save
it to your X4s or share it with others. The MySound app is compatible with
Android devices running OS 4.4 and up, and with iPhones and iPads with iOS 11.0
Battery: The Jaybird X4 is powered by a 3.8-volt Lithium-Ion rechargeable
battery. The battery charges in approximately 2 hours via the included charging
cradle. The in-line remote has 4 contacts on the back that align with the 4 pins
in the charging cradle. Simply snap the remote into the cradle, and plug the USB
cable into your USB power source (5V 500mA power source recommended, 5.5-volt
source max). A fully charged battery provides
approximately 8 hours of playback time. The Quick Charge feature will provide 1
hour of playback time after a 10 minute charge. Each time you turn on the X4s,
you'll hear a battery level announcement, rounded to the nearest 20% level. The
MySound app will indicate the battery level in 1% increments.
In-line Remote/Microphone: The headphones have an in-line
3-button remote control for power, Bluetooth pairing, music playback, and phone
calls. The remote includes an integrated omnidirectional microphone for phone
calls and voice assistant (for Siri, Google Now).
