Pet Shop Boys - I Don't Know What You Want But I Can't Give It Anymore

Our Jabra Engage 55 Mono Headset is designed for professional-sounding conversations - wherever and whenever you work. With a lightweight on-ear headband, it has a low clamping force to minimise pressure and provide maximum comfort all day long. The highlight of our Engage 55 headphone is that you can now make calls without being tied to a base, thanks to the innovative Link 400 USB DECT adapter. This particularly bendable and practical device is pre-paired and can be taken anywhere. Simply plug it into your laptop and start making calls while moving freely (within 490 ft/150 m of your laptop) for additional mobility. With the security-certified DECT adapter, Engage 55 not only has up to 15 times the wireless range of a conventional Bluetooth device, but also keeps your conversations extra secure thanks to military-grade 256-bit encryption algorithms.In addition, it has various features such as wideband audio for a more pleasant calling experience. That's not all, the built-in noise-cancelling microphone suppresses ambient noise, and an adjustable Sidetone ensures that you hear your own voice on calls without having to shout, reducing call fatigue. Furthermore, it is equipped with a Busylight that signals to your colleagues or others nearby when you are on a call, preventing interruptions. On top of that, your ears are reliably protected thanks to SafeTone 2.0, PeakStop, and IntelliTone 2.0 hearing protection technology - preventing sudden loud sound spikes and general sound exposure. For even more flexibility at work, it is certified to work with Microsoft Teams and has a battery life of up to 13 hours which can be easily recharged during calls. It also comes with a 2-year warranty.JabraTechnology for Life’s new rhythm.Whatever you’ve got going on, we’ve got just the thing. So find your rhythm and start enjoying life on your own terms.
