Over-ear Bluetooth headphones with high battery power

The largest model in the JBL-E series works both as a Bluetooth headset and as a wired speakerphone.


The E55BT, available in black, red, and blue, is designed as a convenient over-ear model. It sits comfortably and is non-slip on heads of different sizes thanks to the earcup and temple padding, and adjustable size. The ear cups can also be turned and folded out – for answering quick questions, for example.

Multiple controls on the right ear cup allow straightforward operation: there is a slide for switching on and off with a two-color LED, a volume control, a button for pausing and resuming playback, and another button for quick pairing.

A textile-sheathed connection cable is included for wired operation. This comes with a one-button remote control, an integrated microphone and a 3.5 mm plug angled at 45 degrees.

A light 226 grams in weight, the E55BT is charged in almost two hours via the included USB charging cable and even surpasses the manufacturer’s impressive 20 hours of continuous operation via Bluetooth.


The closed E55BT sits comfortably and offers medium exterior noise attenuation. Thanks to 50 mm drivers, it delivers a full, well-balanced and detailed sound without any striking bass emphasis. Without a doubt, it is recommended for longer lasting music enjoyment in the mobile sector, where it sets itself apart from low-cost competitors and in-ear solutions. With explicitly audiophile models for home use, however, the E55BT is less competitive, which is particularly evident in the depiction of room depth, dynamic imaging and the highest treble.

In quiet environments and at moderate playback volumes, the reproduced frequency range is comprehensive and extends from low bass to the highest treble. I would describe the headset in the critical mid-range, for tones such as voices and strings, as more reserved than warm. The upper frequencies are a bit too offensive for my liking, which is most noticeable in more aggressive rock productions, and at high levels the E55BT also seems a bit strained. Nevertheless, the quality of the handsfree is sufficient and corresponds to the other E-Series models. Those who use the model with Bluetooth, on the other hand, will have to use their smartphone’s microphone.
