Highlights

• Performance - The XSound 2.1R helmet speakers offer amazing sound quality, with solid bass and clear highs that rival some of the best full-sized headphones. However, it's important to note that the maximum volume levels (max 124dB) of these speakers are the loudest we have ever made. Use with caution!
• Music Source - Output power and quality of the device you plug the speakers into will affect the volume and overall sound quality. Use a device with a high-quality output and be careful when adjusting the XSound 2.1R with the added extra volume.
• XSound Kit - Speaker placement is key for audio quality and volume. The XSound 2.1 includes 3M velcro stickers that will keep your speakers stay in place in your helmet. Align the speaker correctly and experience the helmet audio on a new level.
• Connect With - The XSound 2.1R helmet speaker uses a 3.5mm audio pin. Compatible with most bluetooth comms, smartphones and mp3 players. Please ensure that your device has a 3.5mm earbud jack/female plug (not compatible with all Sena Motorcycle Headsets). Pending on audio source level, helmet speakers may require volume boost app or a EAR3 helmet amp for some smartphones, Bluetooth comms and other devices.
