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.

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
