Noxgear 39g: $69.95 Amazon eBay
Pros: Magnetic clip attaches through a shirt/jacket without pins. Blue safety light for visibility when running in low light. It’s only 39g of weight. ~15 hour battery life. Measured bass extension of ~300Hz (-10dB).
Cons: It sounds worse than a clock radio with the worst bass of any speaker. It’s a huge compromise in sound for the small weight.
