Syphon SoundPro: Ultra-Thin 9.6mm Bluetooth Moto Headphones - Glove-Friendly Controls, Massive Sound, IP55 Waterproof, Built-In Mic, Universal Fit With Any Dirt Bike, Snowmobile, and Motorcycle Helmet

Product arrived really quick, packaging was great! Product was easy to install, quick connectivity, design and comfort is great! But as for functionality, after I installed them into my motorcycle helmet I noticed one of the speakers is very soft or muffled, it’s barely half as loud as the other speaker. My product is eligible for return/replaced by July 19. I opened the product July 4. It is now July 7. I cant seem to contact the seller directly, but I requested a return/replacement through amazon. It drives me nuts riding and only one side of my helmet has music and the other side sounds more like a faint echo, if even that. I tried adjusting my settings on spotify and youtube music to see if it was the platform I use to stream my music but that isn’t the case. After a couple of days that faint speaker actually cut out for 10 minutes while riding. It continued to cut in and out during use before I reached out to customer support. I would like someone from Syphon Sound to contact me asap about this problem. I would like a replacement, if not, then a refund would suffice. Either or, id like to resolve this issue instead of waiting around not enjoying the product as it is intended. Update as of July 30, 2025: I got in contact with Travis from Customer Support of Syphon Sound. He was VERY helpful and kept an open line for communication. He advised me to send my unit to them and either they will fix my unit and resend me the same one back OR they will send me a new unit. I sent my faulty unit to their address (at my expense) on the 15th and it got there on the 21st. They sent another unit out to me on the 22nd and I received my new unit on the 26th. I’ve reinstalled them into my helmet on the 28th. So far, this unit works so much better than the first one. Both speakers are equally loud and clear. We shall see how well they hold up through time. I hope this is a new unit as I dont know for sure, if they just fixed my old one and sent me the same one back. If this unit craps out in under 6 months then I will know for sure that these speakers are not built to last. I will just have to wait and see how well they hold up. I REALLY hope it WON’T be the case of Skull Candy Brand headphones that are built with great sound but doesn’t last after a while. I messaged Travis for a follow up asking what was the issue with the first unit but he only told me the tech noted it was faulty with no other details or info that could’ve caused it to crap out on me. I will come back to edit this review if something happens in the near future. But for now, I will change my two star review to a 5 star review. Only because they corrected the problem and was very prompt with communication and quick to send me a “replacement” only after they received my unit. Second Update as of December 28, 2025. Speakers are holding up well, still loud and crisp. I use it 5 of 7 days a week. I ride to and from work daily on my bike as it is my only transportation. Always listening to music while I ride has transformed my riding experience. It’s safe to say that these speakers are great and I am still a satisfied customer. They handle well in rain, shine, wind, and everything in between.

I bought this for my second helmet which is a HJC I-11 I ride on a naked street bike. It Fits the form fitted speaker mounts great even with enough room for the cushioned speaker pads. Great sound even with a little wind noise easily over volumes the wind. Nicely mounts and like that it can adjust song selection and volume with an easy rotation of the mounted power unit. I did not want a unit to talk on the phone or talk to others if in a group. For me this was great. I have two other helmets that have communication Sena units and these speaker are far louder than either of those units. It comes with 3 mounting options. A spacer that can be used to move the speaker toward ear, no spacer and mount just the speaker pod, or snap on the speaker cushion to add a little bass tune to the speaker or a combo of this to fit properly to your helmet to ear spacing. Simple Bluetooth connection with a simple pairing to phone to playing unit. For $199 super fast free shipping through Amazon made this even batter.

I just bought these and been using them for a week now. They suck!!! They let in too much sound from the muffler and wind (YES they were installed correctly). When I tried using on a phone call, other party said too much wind noise and my voice sounded muffled. It was also hard for me to hear what they were saying. Hefty price tag for something that doesn’t work correctly. May I add that even though you add their “bass” ear cushions, they really make no difference with or without them. I’d say these would be good for about $40 but for $200 HAHA hell no. Don’t waste your money

I thought i wouldn't like it at first cuz it looked bulky. Side by side comparison with my ride king headset, wasn't bad at all. I only use my headset for music. I don't take calls while riding, so jamming out to music was why i bought this. Doesn't disappoint. Loud, clear and bass hits suprisingly well (obviously not like a car with sounds). Easy to install, looks clean for what it is and easy to use. The length of the wires was perfect for me. Im rockin a rf1400 shoei helmet and its great.

Price is a bit atrocious hence the 4 stars, but these are nice, fit well, easy install, good battery life and sound quality with easy controls

The comfort is like wearing a helmet with barely anything to disturb you, long rides are easy on the ears and great sound quality with no trouble of hearing over the sound of even my 2stroke dirtbike. After sometime I have noticed after a long time of having it, the control knob becoming a little sticky so it can be a lil hard to make sure it doesn't do anything you don't want like for example changing songs instead of just turning up the volume. After some use and getting used to being easy on the control it gets better

These did not fit into my Shoei helmet at all. The foam covers feel outdated—like something from the Walkman era—and could definitely use improvement. The included Velcro tape doesn’t hold very well either. While the sound quality is good, there needs to be a better way to secure them in place. They came loose while I was wearing them and started moving around inside the helmet, creating uncomfortable pressure points on my ears. They do sound good, so I may try them in my backup helmet to see if they work better there. Overall, I would have returned them, but since they’ve already been used, that’s not an option.

Great addition while riding, super loud and easy to control from just the side of your helmet way better than trying to find a button and to control your audio. I installed mine in a alpine star Sm5 helmet and I will say it took me forever to figure where to place them without them hurting my head and ears but if you lift up the cheek pads and put them about a quarter of the way under it they fit perfect

Really happy to have music in my helmet now, I can hear my music pretty clear up to around 160km/hr. Connects quickly to my phone and was super easy to install.

I've had three Sena units but the Syphon SoundPro wins with better sound quality and volume.

Nos encantó, gracias

ممتاز

Awesome quality and simple to use. I did swap to a Cardo for the ease of switching between helmets for on road and off road riding. Be careful upon install that you don’t rip the cable out of a speaker. Simple and solid speakers for the price
