An ultralight, long-battery wireless over-ear that sits well below Sony's WH-1000XM flagships. Sources agree almost unanimously on two things: it's among the lightest and easiest-to-wear ANC headphones around, and its battery life (roughly 35 hours with noise cancelling on, up to 50 without) is excellent. They also broadly agree the stock tuning is a warm, bass-forward, energetic V-shape rather than a neutral one, and that it responds well to the app's EQ. From there, opinion splits hard: the same elevated bass reads as punchy and fun to some and boomy or loose to others; the midrange is called clear and well-balanced by one camp and recessed or congested by another; the active noise cancelling is 'great for the price' to many and measurably below average to others; and the all-plastic build is 'simple but sturdy' to some and cheap and creaky to plenty more. Nearly everyone agrees the microphone is a weak point, that it doesn't fold or ship with a case, and that it's a much easier recommendation on sale.
About this product
Sony's budget/mid-tier wireless noise-cancelling over-ear (early 2023), several tiers below the flagship WH-1000XM4 and WH-1000XM5 and the wireless-ANC successor to the WH-CH710N. Not the on-ear, ANC-free WH-CH520, nor the bass-focused ULT WEAR, nor the WH-1000XM series it is constantly compared against.
Sony's WH-CH720N arrived in early 2023 as the affordable end of the company's noise-cancelling line — several rungs below the flagship WH-1000XM4 and XM5, and the wireless-ANC successor to the WH-CH710N. Its headline claim is physical: at around 192 grams it's billed as Sony's lightest wireless noise-cancelling headband ever, launched near $149.99 and now routinely found closer to $100.
It borrows real flagship hardware — the same Integrated Processor V1, the Sony Headphones app, multipoint and DSEE upscaling — while quietly dropping LDAC/Hi-Res, touch controls, wear-detection, a folding hinge and a carrying case. That mix earned it a nickname on Sony forums, the 'XM5s on a budget,' and a reputation reviewers and owners genuinely split on: near-unanimous praise for its weight and battery, and real disagreement about its bass-forward sound, its noise cancelling and its all-plastic build.
