Review on 🚲 Enhanced Safety and Convenience: Electric Bike Horn Electronic Bicycle Bell with 4 Soft Sound Modes, Rechargeable Battery, and Waterproof Design for Women, Men, Kids' Tricycles, Scooters, BMX, and MTB by Robert Chandrasekar

Of the four, the less subtle sound is probably the chime sound. Every time you turn it on, it's in the "default" volume. You'll want to turn it off every time you use it. A beep sounds each time a button is pressed. A bit annoying is that there is so much noise to get the device ready to use. I put a large piece of black masking tape on it. It's still too loud. At the default initial volume, all 4 will sound like they are above the speaker's intended volume. It's very distorted. At max volume it's just very loud and distorted electronic noise. Regardless of what effect it acts on. If you're going to use this in a noisy city, you might be fine. However, using this on a commuter bike lane will scare everyone within a block.
