Sena 3s Bluetooth Headset: Quick Review | SMH3

The Sena 3S Bluetooth Headset can best be described as simple but good, a tiny, light headset that weighs about the same as a few coins. Not only is it light, but it is also very easy to use with just two buttons used to control the headset. The headset is available in two versions – the 3S-B with a boom mic or the 3S-W with a Lilliputian mic.

The Sena 3S Motorcycle Bluetooth Headset

The Sena 3S Bluetooth Headset is the next generation of the Nexx SXCOM, the first self-contained motorcycle system which was a joint venture of Sena and Nexx. The headset was introduced at the 2014 AIMExpo Show in Orlando, Florida. The 3S is smaller and lighter than the SX-COM, containing a pair of speakers and a microphone. It is self-contained and uses a Bluetooth stereo headset and intercom. For a cheap motorcycle Bluetooth headset, the 3S has everything you need and nothing you don’t.

Using the Sena 3S

Early motorcycle headsets were extremely difficult to use. Some were so complicated, you needed to tape instructions to the gas tank to remember what sequence of buttons to press. They had very limited range and it was sometimes impossible to talk to passengers through the headsets. Included with the headset is a four-page “Quick Start” booklet or you can download a .pdf form of the leaflet from Sena here. The headset powers up using a quick press of the + and – buttons. Even better, these two buttons control the entire system, whether you want to change the volume, use your phone or pair a GPS or MP3.

SMH3 Sound Quality

The speakers on the Sena 3S are a little bulky, but not any worse than other types of motorcycle headsets. The sound is good and can be heard easily over the sound of the bike. The microphones are sensitive so the mouthpiece does not need to be pressed to your mouth like other systems. In fact, if the mic is too close and the volume to high, the speakers are overwhelmed. Music quality is good as well and you can distinguish bass sounds easily. For a cheap motorcycle Bluetooth headset, the sound is outstanding, however.

Should I Choose the Boom or Wired Version?

Whether to choose the boom or wired version of the 3S depends on several factors. The boom version is designed for open-face helmets due to the location of the operating buttons. The + and – buttons are located along the top end of the microphone and, although you can reach under the face shield to press them, this can be difficult. If you are also wearing thick gloves or have a large face shield, accessing the buttons on the boom mic is not easy. However, the wired version doesn’t work as well in full-face helmets, especially if there is a large chin vent. In those cases, wind noise can affect microphone performance.
