What our customers are saying about Sena 3S Plus Boom Intercom

This motorcycle helmet intercom offers excellent value with a fantastic quality-price ratio. The headset is easy to install and pair, delivering good sound quality. It´s a durable, all-weather unit that works great even in rain and cold weather. While perfect for a single helmet, it includes limited Velcro pads for swapping between multiple helmets. Overall, it´s a top-quality product for any rider looking for reliable performance

Okay for the price

I just wish there were a few more Velcro pads to stick on. The headset's appeal lies in the fact that you can easily swap it between multiple helmets, so one set of Velcro for the helmet and the headset is simply not enough and would cost pennies to produce, but it would be very valuable to the customer. However, if you install it and plan to leave it in your helmet, it's excellent value for money.

I bought two intercoms so I could talk to my partner when we're riding. It's true that I haven't used both at the same time yet, but the one I wear on my helmet and which is connected to my bike works great. If you can't hear well sometimes, it's because my helmet isn't very good, and there's a lot of noise.

The Sena 3s Plus Boom Intercom is a strong contender for riders using open-face or jet helmets who prioritize a minimalist, integrated design. Its use of Bluetooth 5.1 and Advanced Noise Control™ ensures clear communication for music, calls, and intercom chats over a 400-meter range. While it offers a solid set of core features for a connected ride, its primary appeal lies in its sleek form factor and straightforward functionality rather than an extensive list of advanced capabilities or long-range group communication.
