What the listing puts on the page
The paragraph below is Amazon's own sales copy. We keep it quoted and set apart rather than folded into our text, because marketing prose and a description are not the same thing — and because what it leaves out is as useful as what it claims.
Ultra-portable JBL Pro Sound with punchier bass: Don't let its little size fool you. The JBL Go 4 packs a serious musical punch. Your friends won't believe how much great JBL Pro Sound comes out of such a small speaker. Up to 7 hours of playtime plus 2 hours with Playtime Boost: Don't sweat the small stuff like charging your battery. JBL Go 4 gives you up to 7 hours of playtime on a single charge. Tap Playtime Boost to add up to 2 more hours to your battery life.
The price, read properly
Cuts of this depth are the exception in our feed. They generally signal a clearance rather than a promotion, so the window is likely to be short.
One caveat we will not paper over: this is measured against Amazon's own listed price, not against the lowest figure the product has ever carried. Our record of this listing starts on 22 August 2026, so it is a comparison, not a history.
Against what else is on the shelf
The closest tracked listings in audio are Sony WH-CH520 Wireless On-Ear Bluetooth Headphones with Mic at $38.00 (Amazon) and Product Summary: Sony WH-CH520 Wireless On-Ear Bluetooth Headphones with Microphone at $38.00 (Amazon). Both undercut it, so the case for paying more has to come from the table below rather than from the price.
These are the nearest listings by price that our tracker currently holds, not a survey of the market. Anything not on sale at one of the six retailers we follow does not appear here at all.
