20off
Was talking to the online team about how after 2 years of the tevi model I needed to get a replacement they gave me this coupon for their new z3 model but it seems to work site wide.
There's plenty of reviews on YouTube for these earphones. The main advantage being the 10 hour in ear battery life, this will help get through a whole work day without having to remember to do a top up charge during lunch.
They also include their own foam tips which from memory were better than the comply ones I replaced them with.
