What's in the box

  • Cable with mini jack
  • USB charging cable

What you get with these headphones is spartan but sufficient: one audio and one USB charging cable. There is no adapter for a large jack and, unfortunately, they also lack a carrying bag or case to transport them safely.
The ear cups can be folded in sideways to offer a halfway safe transport – the headband, however, remains rigid.

You can forward the Bluetooth wireless signal to a second Synchros E40BT or E50BT, but there was no additional headphone available for the test point, so I can’t judge this function. In addition, the E50BT can also use the conversations of the connected telephone without the need for a wired microphone but – in noisy environments, such as on the street – this capability is limited. It has to be said, though, that if you are indoors, the call quality is very clear, so that’s great!

Sound

In terms of sound, the E50BT presents itself as a balanced all-round talent that stands out especially in the hi-fi sector, although it also performs well in the studio. It is noticeable that at 50 mm, it does benefit from a larger sound converter than many competing models. Nevertheless, it is musically very open and offers a balanced listening pleasure from RnB to classical music. The bass range is defined, crisp and present, but without taking up too much space. The soft highs paired with the rounded bass make even classical music an enjoyable and detailed listening pleasure. At times the headphones may sound a bit hard, but I’d consider this an analytical characteristic rather than being noticeably unpleasant.
The stereo image, on the other hand, is clear and open for headphones. Only the depth gradation could be a bit more detailed, as the individual instruments sometimes fight too hard for space up front.

If you’re looking for an excellent Bluetooth headset that doesn’t make a big hole in your pocket, the E50BT will certainly satisfy. The long battery life makes the receiver a good travel companion. And, thanks to its positive sound characteristics, it also cuts an excellent pose on the couch without an annoying tangle of cables. The outer shielding is good, so that you can immerse yourself in your own world on long journeys – even at low volumes.
