Free Rechargeable Battery Pack with Sennheiser D1 Wireless Systems

For a limited time, end-users who purchase evolution wireless D1 systems can receive a FREE rechargeable Li-Ion battery pack, when they register their new system with Sennheiser.

Sennheiser will give you more power for an incredible performance. If you buy a D1 set from January to June 2016 and register it on the D1 website, you’ll receive a free rechargeable Li-ion battery. All they need from you is your serial number (on the back of your receiver) and some personal information for shipping.

Sennheiser gives you more power on stage. With a battery life of 11 to 15 hours, Sennheiser’s rechargeable Li-ion batteries last much longer than the competition. Take them on tour with you.

Anyone who purchased a D1 set from January 1 to June 30, 2016 and has the associated serial number can participate. Customers who have more than one set can register up to 5 serial numbers. This offer applies to all D1 sets (Vocal, Instrument, Headmic, Lavalier).
