Extremely comfortable classic acoustic tube style earpiece, only that its been upgraded from the inside out. We swapped the old PVC tube for a poly-urethane that is much more elastic/stretchy than its predecessor. If you're running a shift-based operation, you're in for a treat. You can easily connect and disconnect the PU acoustic tube that 1 set of earpiece may be able switch for use with different individuals and still remain sanitary (purchase the extra acoustic tube separately). Simple to use with a 1-wire, in-line style operation. We tried to make the earpiece more comfortable by making it lighter, however, our durability doesn't comprise.

• Lightweight, flexibility provides comfort and enhances day-to-day experience
