MESH: THE NEW STANDARD
The 50S’ Mesh technology brings a new level of robust, reliable connections and smart, flexible intercom message routing thanks to significant technical enhancements made to the original Sena Mesh Intercom algorithm. Sena’s 50S units actively share information between each other within the Mesh network at an astounding rate. An ingenious system of prompts and responses between the Mesh units has resulted in 80% more data being transferred across challenging and harsh conditions. Furthermore, Mesh units quickly determine the ideal pathway to efficiently transmit messages from rider to rider.

Sena’s Mesh technology offers an unprecedented level of intercom audio quality and robust connectivity for all Sena Mesh Intercom users. Tested and proven in the most demanding situations, Sena’s Mesh network keeps the communication lines with your riding partners clear and stable.
MULTI-CHANNEL COMMUNICATION & PRIVATE CONVERSATIONS
The 50S delivers not one, but three different intercom modes available to Sena riders: Multi-Channel Open Mesh Intercom, Group Mesh Intercom, and Bluetooth Intercom.
Multi-Channel Open Mesh Intercom (Open Mesh) features the industry’s first Mesh Intercom channel system. Similar to standard handheld or CB radios, the 50S allows users to switch between nine different channels when operating in Open Mesh mode. Open Mesh offers a single push of a button to click-to-connect to the Mesh Intercom network. It also supports a near-limitless number of users within a range of up to 8 km (min. 6 riders @ 1.6 km intervals). With this ease of connecting, huge user capacity, incredible range, AND the inclusion of the nine-channel feature, the 50S Open Mesh Intercom mode is sure to be a game-changer for large group/club rides.
If you prefer a private group conversation, simply switch to Group Mesh Intercom mode. Group Mesh supports a single, private group for up to 24 participants and the same amazing range as Open Mesh. To ensure privacy, only invited users can join the Group Mesh chat. Whichever of the two Mesh Intercom modes you choose, you’ll enjoy the robust reliability engineered into Sena’s Mesh network.
Traditional four-way Bluetooth Intercom mode continues to be an option for connecting other Sena Bluetooth-enabled users within a 1.2-mile range. Additionally, 50S users can pair with a Sena Bluetooth Intercom user and ‘bridge’ them into a Mesh Intercom conversation.
TAKE CONTROL WITH VOICE COMMANDS
There’s no need to lift a finger when you can ask the 50S to handle it. Voice commands give you control of Sena’s 50S system functions, such as answering the phone or starting up a Group Mesh session. The 50S supports these system voice commands across eight languages, including English, French, German, Spanish, Italian, Chinese, Japanese, and Russian!

THIS is how to #RIDECONNECTED

The included Sena WiFi Adapter handles your rapid charging needs AND can also be programmed to automatically install any available firmware updates to your 50S via your wireless network!

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.
HRV, readiness & total sleep score metrics increased drastically this week. See screenshot :)
Support:
Molds and cushions every crevice under my neck and above shoulders. So comfy
Size:
Adjustable loft but king length is perfect to hug and rest your head. Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated.. my Oura ring showed both nights I was awake every hour. Not good. Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep. Huge.
Weight:
Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders
Softness:
Like the baby bear.. just right.
Comfort:
Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.
If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back.
I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size.
pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking
cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King.
I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem.
A shame, would have given them a great review if they were the correct size

Really Good Cooling Pillows for Sleeping
Color: Blue-ice Plus, Size: Queen(Pack of 2), Color: Blue-ice Plus, Size: Queen(Pack of 2)
These cooling pillows are very soft and provide excellent support for your head and neck. They are adjustable by taking our the stuffing if you need them to be more flat or less firm. The look great and comes in a pack of two which is a great value. During use, I did notice they have great shape retention and it does not take them long to return to their fluffy full shape. I am a hot sleeper and these do keep your head cool - just be aware using a pillow cover does reduce the cool ability but this allows you to adjust for weather like during winters to add a pillow case for extra warmth. Very happy with this purchase and got a second set to replace my old pillows.
