The JBL Tune Flex is JBL's first two-way, fully wireless earphone with an "open-back" or "closed-back" design. It features a futuristic skeleton design.
Open style model for listening while listening
This is the first open-style model that allows two-way use, choosing between an open type that is light and comfortable to wear and can be used for "listening while listening" and a closed-back type that can be used for "focused listening" by wearing an ear-tip. The open-style model is light and comfortable to wear for long periods and is shaped to make it easy to hear surrounding sounds without feeling oppression. In addition, the closed-back "concentrated listening" style has active noise cancellation to reduce ambient noise. The "Focused Listening" style, which is sealed, uses active noise cancellation to reduce ambient noise, allowing you to enjoy your music without being affected by the surrounding noise.
Mechanical "skeleton" design
The skeleton boom that took off in the 1990s. The "skeleton" design is a forerunner of the re-emerging trend. The case and other transparent parts are made of polycarbonate, which is highly transparent, like water and UV-resistant, so there is minimal risk of yellowing or deterioration, and it also has high impact strength and heat resistance. The intricate internal structure visible behind the transparent case has a mechanical, futuristic design finish. The back of the case and the lid are also decorated with the JBL horn mark, representing the brand identity.
Ambient Aware & Talk-Through Function
The case has an ambient aware function that lets in outside sound when necessary and a talk-through process that allows users to talk while wearing the earphones when being spoken to. In addition, the earphones have a "Dual Connect" function that allows one earphone to be used by itself even when the other earphone is stored in the case, eliminating the need to remove the earphones for convenient use frequently.
