JBL Go 4: $49.95 Amazon B&H Photo Video eBay
Newer model: the JBL Go 5, ranked higher, rated 3.2/5.
Pros: A little more bass than the Go 3 and they fixed the strange mids peak. Measured bass extension of ~82Hz (-10dB).
Cons: Not much bass at all, especially with electronic/bass-heavy tracks pushed past ~50% volume. Midrange can sound grainy and treble a bit sizzly; loses clarity at higher volumes.

Sony SRS-XB13: $61.49 Discontinued Amazon eBay
Newer model: the Sony SRS-XB100, ranked higher, rated 2.9/5.
Pros: Sony SRS-XB13 uses 46mm. Its 255 g, claimed 16 hours (Manufacturer specified) battery life, IP67 protection, up to 88dB and mono playback make it a practical option for its intended room or portable use. A removable strap hangs it from a bag or bike. Measured bass extension of 88Hz (-10dB).
Cons: Bass is limited by its 88Hz specification. There is no companion app. No EQ adjustment. Not much bass, and the sound is muddy. Discontinued.
