For all the noise that comes on the open road, the G4’s microphone was good at picking up my voice from within my helmet. I didn’t sound amazing, but those I spoke with could understand me just fine, even up to highways speeds. The buttons are easy to push, even with gloves on. Battery life, charged from USB, was reasonable — hours of use, days of standby.
Because the G4 clips on to the outside of my helmet, its relatively large control pod catches the wind. I definitely felt it pull my head slight to the side on my motorcycle with little wind protection. It’s sometimes difficult to remember which button presses do what — frustrating and potentially dangerous while cruising. Occasionally music from my iPhone would cut out, then come back at random — typically Bluetooth quirks. The hook-and-loop speakers don’t sound amazing for music, although they’re loud and clear for voice.
Should I Buy It?
For riders who need to talk to pillion passengers, other rides, or use their phone, the modular Scale Cardo G4 is a better option than even helmets with Bluetooth built-in. Just don’t expect it to sound as good as earbuds.
