The latest entry from the “sounds too good to be true and yet here we are” department has just dropped at Amazon. Would you believe sub-$40 Sony wireless headphones? Don’t spend too much time in disbelief, because this very real $37 deal on Sony’s WH-CH520 wireless Bluetooth headphones (black model only) is predictably selling very, very quickly.
The WH-CH520 is Sony’s entry-level wireless on-ear headphone, and it dominates that category with 50 hours. That’s enough for a long-haul flight, a festival weekend, or a full work week of all-day use without a recharge. Quick charging via USB-C adds a few hours of playback from a short top-up when the battery does run low, which means forgetting to charge overnight isn’t a crisis.
Everyday Listening
The very non-entry-level sound quality of the WH-CH520 is customizable through Sony’s Headphones Connect app, which adds EQ adjustment and DSEE processing — Sony’s algorithm for upscaling compressed audio files to closer to lossless quality. For anyone streaming at standard quality or listening to older MP3 files, DSEE does audible work on the top end and spatial feel.
The on-ear design is light enough to wear for extended sessions without the pressure buildup that heavier headphones create, and the swivel earcups fold flat for bag storage without a dedicated case. That extended-wear quality can be put to an extreme test thanks to that mindboggling 50-hour battery life.
Seamless Switching
Multipoint connection lets the WH-CH520 pair to two devices simultaneously — useful for anyone switching between a laptop and a phone throughout the day without manual reconnection. The built-in mic handles phone calls clearly enough for everyday use, and Google Fast Pair works for quick initial pairing on Android. Swift Pair covers the same ground for PCs running Windows 10 or 11, so getting these connected doesn’t require navigating Bluetooth settings manually.
No active noise cancellation at this price point is an acceptable trade-off — these aren’t the headphones for blocking out a loud open-plan office. For commutes, casual listening, and remote work in quieter environments, the $37 price tag during this Amazon deal is hard to argue with. This deal is moving quickly and the black version is the only color at this price, so it’s worth moving on sooner rather than later.
