JBL TUNE235BT wireless earbuds

The JBL TUNE235BT are wireless earbuds built for listeners who want long battery life and a secure, lightweight fit. Weighing 19.27 g, they sit comfortably for extended sessions. The 12.5 mm dynamic drivers deliver JBL Pure Bass Sound across a 20 Hz to 20 kHz range. Bluetooth connectivity pairs quickly with phones, tablets and laptops.

JBL Headphones App and multi-point connection

The JBL Headphones App adds a customisable EQ so you can tune the sound to your taste. Multi-point connection lets the earbuds stay linked to two devices at once, switching automatically between a video on a tablet and a call on a smartphone. A three-button remote with microphone handles playback, volume and hands-free calls without reaching for your device. Google Fast Pair simplifies the initial setup on Android.

25-hour battery life with speed charge

A full charge provides up to 25 hours of operating time and takes two hours. Speed charge gives useful listening time after a short top-up, so you are rarely caught without power. The tangle-free flat cable resists knots during storage. An IPX4 rating protects against sweat and light rain, making the earbuds suitable for workouts and outdoor use.

Questions about this item

Will the 12.5 mm dynamic drivers or the flat cable need replacement after heavy daily use?

The 12.5 mm drivers are sealed inside each earbud and have no user-serviceable parts; the tangle-free flat cable is fixed to the housing, so neither component is designed to be swapped out by the owner.

During a full 25-hour listening session what runs out first — battery or Bluetooth range?

The rated operating time is 25 hours on a single charge, and the Bluetooth transmitter works across the 2.4–2.48 GHz band; in normal indoor use the battery will deplete long before the radio link becomes the limiting factor.

How warm do the earbuds get and how much power do they draw when used continuously all day?

At 16 ohms impedance and 98 dB/mW sensitivity the earbuds draw very little current, so they stay close to body temperature even during the full 25-hour battery cycle.
