It is important to know

The Jabra Evolve2 55 MS Mono is designed for those who work a lot in the office or from home and want to be efficient with one ear free. Before purchasing, consider whether you prefer a single-sided (mono) design or would you need better ambient isolation with a dual- or audio model. Your priority between mobility and complete audio immersion is also important.

• The mono version allows you to remain aware of your surroundings and colleagues during use, which is an advantage when working in teams and in open spaces, but it provides poorer noise isolation.
• A wireless connection makes it easier to move around the room, but you need to be aware of possible connection interference if you have multiple Bluetooth devices in use at the same time.
• Active noise cancellation (ANC) improves focus, but it's not as pronounced on mono models as it is on binaural headphones.
• A quality microphone is a big advantage for video calls, but if you often listen to music or need a complete audio experience, this model will be less suitable.

Answers to frequently asked questions

Can I connect the Jabra Evolve2 55 MS Mono to multiple devices at the same time?

The model supports Bluetooth connectivity with multiple devices, allowing you to quickly switch between your computer and phone.

How many hours of use is the mono version of these headphones suitable for?

Their lightweight design and single-ear design make them suitable for hours of use, but if you need complete sound isolation, models with both ears covered are more comfortable for very long sessions.

Is the ANC on the mono version as effective as on the stereo models?

With mono headphones, the ANC effect is limited because the other ear is not covered - the lack of complete sound isolation remains the main compromise.

Are these headphones suitable for listening to music?

The focus of this model is on voice applications and calls, so they are not the best choice for more demanding music listening.

How stable is the Bluetooth connection in a crowded office environment?

The wireless connection is stable if there are not too many simultaneous Bluetooth devices; in the case of saturated offices, interference may occasionally occur.
