How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a lightweight, app-tuned noise-canceling headset from a brand with decades of audio engineering behind it, choose Sony WH-CH720N; if you need marathon battery life, Hi-Res LDAC audio and a foldable travel design, choose 1Mii Y8+.
• Sony WH-CH720N — biggest strength: Sony's lightest wireless noise-canceling over-ear design, with Adaptive Sound Control and a proven processor-and-sensor ANC setup.
• Sony WH-CH720N — biggest trade-off: 35 hours of battery is solid, but it's a fraction of what the 1Mii Y8+ claims, and the plastic build is functional rather than premium.
• 1Mii Y8+ — biggest strength: A claimed 100-hour battery, LDAC Hi-Res Audio support, 40mm drivers and 22 EQ presets through the YeeMall app.
• 1Mii Y8+ — biggest trade-off: LDAC only works if your source device supports it, and the AI/translation features live entirely inside the app ecosystem.
• Who each is for: Sony WH-CH720N suits commuters and office workers who want reliable ANC and a light fit; the 1Mii Y8+ suits frequent flyers, students and tinkerers who want huge battery and deep sound customization.
The WH-CH720N is Sony's play for the everyday listener who wants noise canceling without the bulk. It uses an Integrated Processor V1 paired with Dual Noise Sensor technology, and Sony pairs that hardware with Adaptive Sound Control — the headset adjusts its ambient sound handling based on where you are and what you're doing. In practice, that means it's built for people who move between a noisy commute, a shared office and a quiet living room in the same day and don't want to fiddle with settings each time.
On sound, you get 30mm dynamic drivers plus DSEE, which Sony uses to restore detail lost when compressed audio is streamed. There's an adjustable EQ in the Sony Headphones Connect app, and 360 Reality Audio is on board for spatial mixes. Bluetooth 5.2 with multipoint lets you stay connected to two devices at once and jump between a laptop call and your phone without repairing. Battery is rated at up to 35 hours with noise canceling on, and a roughly 3-minute quick charge buys about an hour of playback — genuinely useful when you're walking out the door and realize you forgot to plug in. A 3.5mm cable is included, so you can go wired when the battery dies or on a flight with an in-seat system.
Who should buy it: commuters, remote workers, and anyone who prioritizes a light, comfortable over-ear fit and wants ANC that adapts automatically. Dual beamforming mics with Precise Voice Pickup and a wind noise reduction structure make it a reasonable choice for calls too.
Who should skip it: if you want maximum battery headroom, Hi-Res LDAC codec support, or a folding design that packs small, this isn't the pick. The build is plastic, there's no headphone jack on the headphone itself in the wireless-first sense, and the tuning options, while real, are narrower than what the 1Mii app offers.
The Y8+ is aimed squarely at people who hate charging. 1Mii rates it at 100 hours of continuous playback, and a 10-minute quick charge adds around 5 hours. That math matters on a long-haul trip or a week of back-to-back study sessions — you can plausibly leave the USB-C cable at home. Charging from empty takes about 3 hours, so it's a slower top-up but a much longer runway.
Audio is where the Y8+ makes its case to enthusiasts. It uses 40mm dynamic drivers with a 20Hz–40kHz frequency response, 16 ohm impedance and 105dB sensitivity, and it supports LDAC for Hi-Res Audio streaming. The caveat 1Mii states plainly: LDAC only works when the paired Bluetooth device supports it, so a phone without LDAC will fall back to a standard codec. There's also a 3.5mm jack and AUX cable in the box, so wired listening is an option.
Noise canceling is hybrid ANC with four microphones and a proprietary algorithm, targeting low-frequency rumble like plane engines, car noise and office hum. Transparency mode lets you hear announcements or a barista without pulling the headphones off. Controls are a mix of physical buttons and app control through YeeMall, where you get 22 preset sound effects — Deep Bass, Classic, Pop, Rock, Jazz, Country and more — plus custom EQ, battery monitoring and ANC/Transparency switching.
The other differentiator is the AI layer: on-the-go voice chat, English practice, contextual learning and translation across 103 languages, all driven from the app. Comfort-wise it's memory foam with hydrolysis-resistant protein leather, a foldable frame and an adjustable headband, and it ships with a pouch.
Who should buy it: frequent travelers, students, language learners and anyone who wants to tune their own sound signature and rarely thinks about charging. Who should skip it: if you want a set-and-forget headset with no app dependency, or your phone doesn't support LDAC and you don't care about EQ tinkering, the extra features won't earn their keep.
Side-by-Side: Which Should You Choose?
• Best for battery life → 1Mii Y8+. A claimed 100 hours versus 35 hours is not a close contest.
• Best for Hi-Res audio and codec flexibility → 1Mii Y8+. LDAC support and a 40mm driver with a 40kHz top end give it the edge on paper for detail.
• Best for lightweight all-day comfort → Sony WH-CH720N. Sony bills it as its lightest wireless noise-canceling headband model, and the over-ear closed-back design is built for long sessions.
• Best for travel convenience → 1Mii Y8+. The foldable frame and included pouch make it easier to pack than a fixed-headband design.
• Best for call clarity on the move → Sony WH-CH720N. Dual beamforming mics, Precise Voice Pickup and a wind noise reduction structure are specifically aimed at voice.
• Best for sound customization → 1Mii Y8+. 22 presets plus custom EQ through the YeeMall app beats a single adjustable EQ.
• Best for app-free simplicity → Sony WH-CH720N. It works well out of the box; you don't need the app to get the core experience.
• Best for language learners and AI tinkerers → 1Mii Y8+. Translation across 103 languages and AI voice chat are genuinely unusual at this tier.
If I had to pick one, I'd buy the Sony WH-CH720N. In my opinion, most people's real pain point isn't battery — it's noise that changes hour to hour, and Sony's Adaptive Sound Control plus the V1 processor and dual noise sensors handle that automatically. The light fit and the beamforming mic setup make it the better daily driver for commuting and calls, and 35 hours is plenty for a normal week. I'd only steer you to the 1Mii Y8+ if you fly long-haul, want LDAC and custom EQ, or genuinely need triple-digit battery life — in which case it's the more interesting and more feature-dense buy.
On the spec sheets, yes — 1Mii rates the Y8+ at up to 100 hours of playback versus Sony's up to 35 hours with noise canceling on. The Y8+ also adds a quick charge that 1Mii says delivers about 5 hours from a 10-minute top-up.
Not according to the specs here. Sony lists 30mm dynamic drivers, DSEE sound enhancement, adjustable EQ and 360 Reality Audio, with Bluetooth 5.2. LDAC is a 1Mii Y8+ feature in this comparison, and it only works when your paired device supports it.
Both come with a 3.5mm audio cable, so yes — you can listen wired on either. The 1Mii Y8+ lists a 3.5mm jack and an AUX cable in the box; the Sony WH-CH720N ships with a 3.5mm audio cable and USB-C charging cable.
