Review on 🎧 Sena Pi: High-Performance Bluetooth Intercom Headset for Cycling and Multi-Sport Helmets (Universal Fit) by Brian Page

We bought 2 to make a working intercom (only one unit in the box). One of these units worked exactly as expected, but the other doesn't last more than 48 hours on a charge. If both work as intended I would give the units 4 stars (instead of 5 as I think the price of the item is high). I am contacting SENA Customer Service for a warranty return. When the devices work +ve- Excellent intercom that works great at a reasonable distance - we had connection on the open road in a straight line for about 700m with no interference or loss. . If you want it to be basically an internal connection between two drivers, it works great in that role. Pairing with the phone is excellent, calls are clear and removes most wind noise. Music from the phone is quite clear - the sound quality is not very good but sufficient. so I can sing along on the way to work. -ve- they don't like rain and tend to switch off from time to time when rain hits them. - The braided cable between the left and right speakers is difficult to secure in the helmet. and can be a little uncomfortable on the head if seated incorrectly
