Syphon SoundPro

Loud but sound quality could be better

Yes they are loud. Yes they are easy to install. To me the sound is tinny and lacking highs and lower frequency response. I've tried maxing out my equilizer in my phone with very little improvement. For 200.00 I would expect better. To me sound is average. I did call my buddy using the system and he says sound was good bit I was not riding . If you're looking for loud and convenient features then they work pretty good.

Siphon SoundPro Pros and Cons

Overall, I am happy with the product. Here’s some feedback: Pros: Strong battery life, charges with USBC Great sound quality and controls for any music playlist Fits nicely in the helmet’s audio holes Cons: Microphone quality is lacking. Hard to convey anything with the microphone on an earpiece. Phone calls are easy to connect to, but I am not easily understood. I tested this in a discord call and several phone calls. Overall results: This is a great product for input vs output. Great sound quality and audio performance with music and listening. Unfortunately, the mic output to a call is too muffled for others to hear you.

Thunder down under.

This amazing piece of kit is worth every penny. The thunderous base clear mid and sharp top end, Provide an awesome companion on long solo rides. Easy to fit plenty of extras so you can transfer the unit to multiple helmets. The controller is really intuitive and easy to use with gloves, Bluetooth connectivity is phenomenal.
