Features and Benefits
Adaptive Noise Cancelling with Smart Ambient
Hear more of what you want and less of what you don’t. Adaptive Noise Cancelling adjusts automatically
or via the My JBL Headphones App to control distractions and stimulate motivation. Smart Ambient helps
you feel safe on walks and runs or allows you to chat with a friend while listening to music.
JBL Signature Sound
Reflect Flow Pro earbuds sound as good as they look, utilizing 6.8mm dynamic drivers to deliver
incredible JBL Signature Sound whether you’re in your office or crushing your workout in the great
outdoors.
Perfect calls, zero noise
Never worry about your voice dropping out when you’re outside, in a crowd, or running on a breezy day.
Two beamforming mics plus a third for wind suppression ensure you’ll stay connected wherever you are
with crystal clear sound and no audio failure on either side during calls.
IP68 protection and secure fit
Extreme IP68 water and dustproofing means workouts on land are no sweat in any weather or conditions
– but so is surfing with your JBL Reflect Pro earbuds, or rinsing them after a workout, all without missing
a beat. Designed to enhance your performance, the earbuds POWERFINS in 4 sizes keep them safely and
comfortably in your ears.
30 Hours of playtime with Qi-compatible wireless charging
Work or work out on the go with the convenience of Qi-compatible wireless charging. Nothing can stop
you with 10 hours of power in the earbuds and 20 in the case for seamless connection all day.
Get help just by using your voice
Get help from your preferred voice assistant using your voice or with a tap on the earbud. Activate ANC or
Ambient Aware, check the battery life or power off your JBL Reflect Flow Pro simply with your voice with
Hey Google. Use the all-new My JBL Headphones App to easily set your preferred voice assistants.
Customizable all-access touch control
Should a call come in during your run or yoga session, answer or reject it with a simple touch of the
earbud. Engage your voice assistant, start or stop your music, or adjust the volume in either earbud with
a quick tap or by downloading the free My JBL Headphones App to personalize your Reflect Flow Pro
sound and functionality.
Maximize the comfort to improve the performance
The last thing you need is for your earbuds to hurt or fall out while working out. Use the JBL Headphones
App and the Check My Best Fit feature to get the best sound performance and maximum comfort.
By testing for sound leakage during headphone usage, the app quickly determines when you’re getting
the best fit from the ear tips.
Dual Connect + Sync
From the moment you open the case, Dual Connect + Sync starts the Bluetooth sync process for an
ultra-stable connection. Plus, you can customize the functionality of each earbud through the app and
use either or both to manage calls, music and Voice Assistant, saving battery. While you enjoy music from
one bud, the other one stays in the case charging up for endless fun!
