Sena 20S Motorcycle Bluetooth Headset Review

Bluetooth technology has come a long way since it was invented in the 1990s by an Erikson employee named Dr. Jaap Haartsen.

In 2018, there are 10 billion Bluetooth-enabled devices. That's more than double from 2012.

Now, it's more affordable and available to have motorcycle helmets with the Bluetooth technology.

But if you have a helmet you love already, you can still enjoy Bluetooth connectivity. Luckily for you, the Sena 20S-01D communication system can add Bluetooth 4.1 connectivity to any helmet.

Having Bluetooth while you ride will let you communicate with other riders, listen to music and even get GPS directions.

Unlike Bluetooth kits for cars, units for motorcycle must be able to endure extreme weather and noise conditions.

Read on to discover what the Sena 20s Bluetooth headset has to offer.

Sena 20s Features

There are 2 purchase options. You can either purchase only one unit or grab the discounted dual bundle so you can gift one to a biker bud.

The unit attaches to the outside of any bike helmet. It comes with 2 speakers that you'll stick in your helmet, anywhere you want. A microphone plugs into a port on the unit.

You'll get 13 hours of talk time with Sena headset and worldwide radio regions. The Lithium polymer battery requires just 2.5 hours to charge from depleted.

The Sena 20s can handle whatever you're up for. It operates at temperatures from -10 -55 degrees Celsius (14 - 131 degrees F).

The voice control feature lets you keep both hands on the handlebars as you make and answer phone calls and skip songs.

The audio GPS navigation instructions are handy for road trips. The intercom feature lets you chat with your passenger or other bikers.

The free Sena Smartphone app gives you an additional user guide that complements the owner's manual that comes in the box. The app is compatible with both Android and iPhone. It allows you to configure device settings, set groups of intercom friends, and more.


Thanks to Bluetooth 4.1 technology, the Sena 20s lets you talk at distances up to 1.2 miles apart.

If you need to reach for that top range, just flip up the antenna.


The Sena headset pairs with two devices. This is great if you and your passenger each have a smartphone or you want to pair a GPS and a phone simultaneously.

Pairing your device to the motorcycle Bluetooth headset is simple and quick. After the initial pairing, every time your device comes close to your helmet, it will automatically connect.

Intercom Pairing

All Sena headsets can be paired up to other headsets for Bluetooth intercom conversation. The Sena 20s lets you pair up to 9 headsets.

There are 2 ways to pair headsets.

  1. First, turn on the two Sena headsets. Press and hold the Jog Dial of both headsets for 6 seconds. You will hear a voice prompt saying "Intercom pairing".
  2. This method of pairing applies only to the Sena 20s models. First, remove the two headsets from the clamps. Grab each headset and shake it simultaneously until the green LEDs of both units start to flash rapidly.

The intercom pairing queue is 'Last-Come, First-Served'. If a headset has multiple paired headsets for intercom conversations, the last paired headset is set as friend #1.

To chat with the most recently added intercom friend, tap the Jog Dial once. To communicate with the second intercom friend needs 2 taps of the Jog Dial. And so on,

Bonus: Sena 20 uses a universal Intercom protocol which means it can be used with all Sena and non-Sena Bluetooth headsets on the market. So if your buddies have a different brand, you can still communicate on the open road.

Sound Quality

The Sena 20 boasts an advanced noise-canceling technology that blocks wind noise. So when you are traveling at high speeds, you'll still have crystal-clear audio.

One of the coolest settings is that you can program the Sena 20 to just turn down the music when there is an incoming call or a GPS voice instruction. Most Bluetooth headsets just turn off the music completely.

You get access to FM radio with 10 preset options available. Reviewers say that the sound quality is great when listening to the radio.

Another cool feature is Ambient Mode. When you double-click a specific button on the bottom of the mount, all other audio stops. Then you are able to have a conversation with someone at a red light or give directions to a pedestrian.


Voice command and motion sensors are both features on the Sena Bluetooth.

As we mentioned, the motion sensor technology makes pairing headsets absolutely simple - just shake to pair.

When you are on the open road, you have complete control of the Sena 20 through hands-free voice commands. This ensures you are safe and focused on driving instead of fiddling with menus.

The Sena's intuitive technology ensures an enjoyable ride where you can seamlessly move through music, phone, and intercom features.

Cool Extras

Sena makes a host of innovative motorcycle Bluetooth communications devices. They offer cameras that can be mounted to helmets, handlebar remotes, smart helmets and more.

Once you have the Sena 20, you have access to a slew of other cool gear you didn't even know you needed. You can pair your Sena Bluetooth with other Sena products for an unbelievable experience.

Pair the 20S with a Sena Bluetooth audiopack. You'll be able to capture your adventures in HG and narrate them in real-time. It lets you mix multiple inputs from intercom channels. The Audio Pack is compatible with GoPro, HERO3, 3+ and 4 cameras.

or the Sena Prism Bluetooth Action Camera lets you record HD video that includes the mic from your headset and the intercom audio from your buddies. You'll be able to relive and share the experience with family and friends.

An optional Handlebar Remote control gives you even more flexibility in how you interact and control your Sena 20s.

Final Thoughts

The Sena 20S is ranked number 1 on the best Sena Helmet Speakers list out of 98 Sena Helmet Speakers found across the web. We hope this post has helped you understand the ins and outs of this Bluetooth headset for your motorcycle helmet.
