JBL Tune 125BT Bluetooth 5.0 Wireless In-Ear Neckband Headphones

JBL Tune 125BT Bluetooth 5.0 Wireless In-Ear Neckband Headphones

The JBL Tune 125BT wireless in-ear headphones combine 8.6 mm dynamic drivers, JBL Pure Bass Sound, Bluetooth 5.0, and up to 16 hours of playback in a lightweight neckband-style design. Magnetic earbuds, a flat cable, and an integrated three-button remote make them practical for commuting, work, travel, and everyday mobile listening.

Multipoint Bluetooth connectivity allows the Tune 125BT to work with two compatible devices, helping users move between entertainment and calls without repeatedly disconnecting and pairing. The built-in microphone supports hands-free communication, while the three-button inline remote provides convenient music and call control. Voice assistant support also provides access to compatible smart-device assistant functions.

The internal 3.7V, 120mAh lithium-ion polymer battery recharges through USB-C and reaches a full charge in approximately two hours. JBL's current product information specifies up to 16 hours of playback and a speed-charge function that provides one additional hour after a 10-minute charge. Three included eartip sizes help users adjust the in-ear fit for comfort and consistent listening.

Bluetooth 5.0 Wireless Listening

The Tune 125BT uses Bluetooth 5.0 with HFP, HSP, A2DP, and AVRCP profile support. Its wireless system operates across the 2.402 GHz to 2.48 GHz frequency range and supports multipoint connectivity for users who regularly move between two paired devices.

16-Hour Battery with USB-C Charging

The rechargeable 120mAh lithium-ion polymer battery provides up to 16 hours of music playback. JBL specifies approximately two hours for a complete recharge from empty, while the current product page states that a 10-minute speed charge provides approximately one additional hour of playback.

Magnetic Earbuds for Easier Cable Management

Magnets built into the earbuds allow them to connect when hanging around the user's neck. Combined with the flat cable construction, this helps keep the Tune 125BT organized between listening sessions and reduces loose movement during everyday use.

Hands-Free Calls and Voice Assistant Access

A built-in microphone and three-button remote support wireless calls and music control from the cable. The headphones also support access to a compatible mobile device's voice assistant, providing another way to interact with connected devices without reaching for the phone.
