Pros> loud, long battery life, easy to install/use, cheap

The battery life seems good and I can't comment on the intercom feature.

The battery life is great and sound quality is good as well

Battery charges, pairs with Bluetooth, plays music, microphone works well, etc

Headphone does not fit flush with shoei rf1200, but works well enough not to notice.

The bluetooth connection is fine to the phone and works great, but connecting to another helmet is very limited

When working, it's great - easy to hear, good volume and clarity - and I can use siri

Easy installation and decent performance

Installation was pretty straightforward and easy

Installation was easy

I simply needed something to listen to music (got tired of the pressure points from my ear buds) and this unit is perfect

One unit works great, but the other cuts out constantly when trying to talk

I really like this unit.

Would recommend this product to anyone looking for hands-free telephone call capability and the ability to listen and control your music all via bluetooth

One of the greatest purchases thus far

low profile, excellent sound quality, a definite best purchase!

I tell you what, I do not regret this purchase

Easy installation and decent performance

Although I love the size and discreetness of the S3, the performance is underwhelming.

I bought it, and the sena S3 with boom mic, and I prefer this one.

I would recommend this Sena 3S Bluetooth Headset to anyone with a full-face helmet

No matter what volume, the speaker was distorted with a garbled mess and got progressively worse with any kind of bass and the louder sounds (left side was flawless)

Volume could be an issue

Negatives: installed in Arai Quantum V, the cord from L to R speakers just a bit short, as is the mic cord.

Works well as advertised

My intention was to put the S3 on my dual sport helmet (especially for the long rides), but the wind noise of the various vents and visor drowns the S3 sound.

It's small (which looks good and cuts down wind noise) and does the job though
