Verified Customer Reviews for Shoei Sena SRL-EXT Bluetooth Communication System
It works well enough. Connectivity is really good and connects every time. Buttons are nice and clicks but volume is low and the mic doesn't work with voice assistants very well for some reason
Easy to install and easy to use. The sound quality is incredible and well worth the money. Highly recommend.
I had the shoei Gt Air for years with the 10u head set in and was impressed at the quality and design. Then upgraded to the NXR2 and fitted the SLR EXT and it's even better. Great SOUND and Battery life. Just makes riding even better. Reduces wind noise and also allows me to hear my Garmin Zoom xt. Overall just a great bit of kit and would recommended to everyone. Also like the fact you can adjust the depth in which the speakers sit in the helmet with all the pads provided. 10/10 for me would be lost with out it. I've rode for years with out them and 6 weeks lately in my new lid but just missed having the music in the back ground and helping remove most of the wind noise. The Sena is brilliant and like I mentioned I've had two different models over the years and the only seem to get better.

Mesh and Bluetooth Intercom
The SRL-EXT offers both Mesh and traditional 4-way Bluetooth intercom, allowing for compatibility with any Sena or Sena-powered device. Sena's industry-leading Mesh Intercom™ communication platform has two modes: Multi-Channel Open Mesh Intercom™ (Open Mesh) and Group Mesh Intercom™.
Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom™ network and features the industry's first Mesh Intercom™ channel system. Like standard handheld or CB radios, Open Mesh lets users switch between nine channels. It also supports a near-limitless number of users within a range of up to 5 miles / 8 km (min. 6 riders @ 1 mi / 1.6 km intervals).
Group Mesh supports a single, private group for up to 24 participants and the same range as Open Mesh for a more intimate group conversation. Only invited users can join the Group Mesh chat. Open Mesh and Group Mesh provide unprecedented intercom audio quality and robust connectivity.
Voice Commands
Sena's voice commands give you control of the SRL-Mesh system functions, such as answering the phone or starting up a Group Mesh session across eight languages. The SRL-Mesh can also connect to Google Assistant or Apple's Siri with just a simple voice command, allowing you to tap into your smartphone's features, including GPS navigation, music playback, voice dialling and more.
Sena App
The optional Sena Motorcycles App gives users a way to configure the SRL-Mesh device settings visually, including the ability to manage channel settings for Open Mesh remotely, or set a private group for Group Mesh. Available for both Android and iPhone via Google Play or Apple App store.
