The Jabra Evolve 40 MS Stereo Corded Headset is a clever little headset. It comes with both a USB AND a 3.5mm connection to plug into your smartphone, PC or tablet. So you have just one headset to use at work with your softphone and on your way home to listen to music from your mobile phone. This wired USB headset would mainly suit a desktop but would be compatible with a select few handsets (E.G. Yealink T5 series) if you are unsure, feel free to give us a call or send us an email and our staff will gladly check for you.
