TODO: 2–3 paragraph intro covering who the Sony WH-CH720N is for, when it makes sense vs alternatives, and a quick teaser of the verdict.
Design and build
TODO: 150 words on materials, weight, fit, controls, foldability, included accessories.
Sound quality
TODO: 150 words on tonal balance, soundstage, codec support (SBC/AAC/aptX/LDAC), how it handles different genres.
Noise cancellation
TODO: 150 words on ANC effectiveness — low-frequency drone (planes, trains), mid-frequency (chatter), and high-frequency (keyboards). Compare to direct rivals.
Battery and charging
TODO: 100 words on real-world battery vs claimed, fast-charge speed, USB-C vs proprietary.
Calls and microphone
TODO: 100 words on mic clarity in quiet vs windy/noisy environments, multipoint behavior.
Verdict
The best daily-wear ANC headphones under $150. Sony nailed weight and battery life — the two specs you actually feel. Build quality is the only place they cut corners.
