JBL Tune 135BT and Amazon-Exclusive Tune 235BT Neckband Bluetooth Earphones Launch With 25-Hour Battery and Multipoint

The addition of app-level control subtly shifts the tuning philosophy. While the baseline voicing stays anchored in JBL’s familiar low-end emphasis, software EQ and device management introduce a layer of user agency previously absent from this series. This bridges a gap between casual portability and enthusiast expectations, especially for listeners accustomed to tailoring mid-bass bloom or upper-mid presence to suit different genres. Multipoint behavior further underscores this practical orientation, allowing seamless transitions between sources without renegotiating connections—an area where many budget Bluetooth designs still stumble.

Acoustically, the divergence between the canal-style and open-fit variants highlights two interpretations of everyday listening. The sealed in-ear design favors pressure-assisted bass extension and isolation, while the open-fit approach trades low-frequency authority for spatial awareness and comfort. Both benefit from improved environmental resistance and lightweight construction, reinforcing their role as daily companions rather than audiophile statement pieces. In that sense, JBL’s update reads as a maturation of a long-running platform, tuned for modern usage patterns while deliberately avoiding unnecessary technical bravado.
