The HSL 10 II Handset Lifter from Sennheiser is designed to elevate a desktop phone that requires lifting when in use with a wireless DECT headset solution, such as the SDW 5015, DW Pro1, SD Office, and more. In addition to its wide range of compatibility, the HSL 10 II allows you to answer and end phone calls without the need for touching the receiver. Other neat features include ring tone detection for up to two unique sounds, an extendable design that allows you to adjust the height of your connected phone, and two kits for fixation and adaption.
