Putting on headphones is one way of signalling to colleagues that you don’t want to be interrupted, but in workplaces where everyone uses a headset for phone calls, working out who is busy can still be tricky. Jabra’s new Evolve range of headsets includes a “Busy Light” so that fellow workers know not to interrupt.
The red light ring activates automatically whenever you're making a phone call using the headset, and can also be switched on manually. It features on the Evolve 40, 65 and 80 models, which also include a retractable boom mike (so you can use the headset for regular music listening out of the office) and the ability to use either a 3.5-inch or USB connector.
It's a simple concept, but an effective idea. The 40 has an RRP of $141.90.
