With the Sennheiser RS275, you can enjoy your favorite movies and series by yourself without bothering anyone. That's mainly useful in the evening when you can't turn up the volume. The headphones have Virtual Surround Sound, so movies and series sound realistic. That way, you're fully immersed. Thanks to Sennheiser Speech Clarity, voices sound loud and clear and you don't miss a single word. The 50-hour battery life allows you to use the headphones multiple evenings in a row without charging in between. You can also connect the headphones to your smartphone or tablet, so you can listen to music. Others can connect their own headphones to the RS275 via Auracast. That way, everyone can enjoy the movie at the volume they prefer.
