Features

Overview: The JBL Tune Flex 2 ear buds are true wireless in-ear headphones with JBL's Pure Bass Sound and JBL Spatial Sound. Each ear bud has a built-in rechargeable battery, plus controls for power, music playback, phone calls, and activating your favorite voice assistant. The ear buds feature Adaptive Noise Cancelling with Smart Ambient. Tune Flex 2 ear buds come with 4 pairs of ear tips (1 open, 3 sealing), a charging cable, and a hard, flip-top charging case.

Drivers: The JBL Tune Flex 2 ear buds are equipped with 12mm dynamic drivers that deliver the JBL Pure Bass Sound with a wide frequency range of 20Hz-20kHz. JBL Spatial Sound transforms the stereo sound from any source and turns it into a more immersive sound experience.

Ear Tips: Two types of ear tips are included with the Tune Flex 2. The open ear tips (1 pair included) help you to stay aware of your surroundings while wearing the ear buds. The sealing ear tips (3 pairs included) create a seal in your ear canal and provide a measure of passive noise cancelling.

Water-Resistant: The Tune Flex 2 headphones are IP54-rated for water and sweat resistance. You can wear them while you work out or in bad weather without worry.

Bluetooth: The ear buds connect to your smartphone or tablet via Bluetooth version 5.3. The ear buds support A2DP (v1.4), AVRCP (v1.6.2), and HFP (v1.8). When you remove the ear buds from the charging case, they automatically enter pairing mode. Google's Fast Pair immediately pairs the Tune Flex 2 to your Android device (requires 6.0 and up). Replacing them in the charging case powers them off.

Stereo/Mono Modes: The Tune Flex 2 lets you pair both the left and right ear buds to your device for stereo mode. You can also choose to pair either the left or right ear bud to operate in mono mode.

6 Microphones: Each ear bud has three built-in microphones. Two beamforming microphones provide excellent voice clarity for phone calls and to communicate with your Voice Assistant while a third inner microphone isolates noise.

Voice Assistants: The Tune Flex 2 is compatible with a wide variety of digital Voice Assistants. You can activate your smartphone's built-in voice assistant like Siri and Bixby to get the weather forecast, set timers, play music, or a host of other activities. Activation of your Voice Assistant can be done by pressing a button on your ear buds, through the JBL Headphones app, or by using your voice.

VoiceAware: In the JBL Headphones App, you can adjust the amount of your own voice you can hear through the headphones. The VoiceAware feature can be turned on or off, and the level set to low, mid, or high.

Adaptive Noise Cancelling/Ambient Aware/TalkThru: The Adaptive Noise Cancelling (ANC) and Ambient Aware features let you choose whether you want to shut out your environment or connect to it. ANC lets you focus on your music or just enjoy the silence by eliminating noise from your surroundings. Adaptive Noise Cancelling lets you choose how much of the outside sound you want to let in. Microphones pick up ambient noise and ANC applies an equal-but-opposite audio signal to cancel that noise. If you want to be more aware of your surroundings, you can enable Ambient Aware, which take the sounds of your surroundings and send them into the earphones. You'll be able to listen to public announcements, or just hear what's going on around you, without removing your ear buds. The TalkThru feature simply lowers the level of the music in your earphones to let you talk to your friends without removing the ear buds.

Controls: The JBL Tune Flex 2 features basic phone, music playback, and Voice Assistant controls on each ear bud. You can also activate ANC, Ambient Aware, and TalkThru. Advanced controls are available through the JBL Headphones app, including assigning custom controls to each ear bud. The ear buds also have sensors that can detect when you place the ear buds in your ears and when you remove them. When playing music, the music will pause when you remove one or both ear buds, and will resume playback when you replace the ear buds in your ear.

JBL Headphones App: The JBL Headphones App, available for iPhone / iPod touch (with iOS 14.0 or later) and Android (7.0 and up), lets you customize your Tune Flex 2 listening experience. Through the app, you can set up your Voice Assistant and assign actions to the desired buttons on the earbuds. You can activate and adjust the Adaptive Noise Cancellation, Ambient Aware, and TalkThru features. The app's Custom EQ provides three preset EQ curves or you can adjust the 10-band EQ to personalize your sound the way you like it.

Rechargeable Batteries: Each of the JBL Tune Flex 2 ear buds contains a 3.85-volt 55mAh Lithium-Ion rechargeable battery. The charging case contains its own 3.85-volt 545mAh Lithium-Ion rechargeable battery. The ear buds provide up to 12 hours of continuous music playback (ANC off), or 8 hours with ANC on. Talk time is approximately 5 hours with ANC off and 4.5 hours with ANC on. The charging case adds another 36 hours for up to 48 hours of total combined playback time with ANC off, and 36 hours total with ANC on. The ear buds charge in the case in approximately two hours in the provided case with the supplied USB-C cable. A 10-minute quick charge gives you approximately 3 hours of playback time.
