How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want real active noise cancellation with a 96-hour charging case and a deeper feature set, choose GNMN Active Noise Cancelling; if you need the newer Bluetooth 5.4 connection and a lighter, over-ear hook fit for long workouts, choose PEFUPEW Earbuds.
• GNMN Active Noise Cancelling — biggest strength: true active noise cancellation rated up to 45dB depth, plus a transparency mode you can toggle without removing the buds, and up to 96 hours of total playback from the charging case.
• GNMN Active Noise Cancelling — biggest trade-off: it's the bulkier, more feature-dense option (in-ear with ear hooks and a larger chamber design), so it asks you to manage modes and a bigger case.
• PEFUPEW Earbuds — biggest strength: a modern Bluetooth 5.4 chipset with a rated 40ms low-latency transmission, four ENC microphones for calls, and a soft over-ear hook design that keeps pressure off the ear canal.
• PEFUPEW Earbuds — biggest trade-off: its noise control is passive (sound isolation) rather than active cancellation, and total playback is rated up to 48 hours versus GNMN's 96.
• Who each pick is for: pick GNMN if you fly, commute, or work in loud rooms and want to actively silence the world; pick PEFUPEW if your priority is a comfortable over-ear hook fit and the latest Bluetooth connection for gym and outdoor sessions.
The GNMN V7 leads with active noise cancellation, and the spec sheet puts its cancellation depth at up to 45dB. That's the headline. This is a bud that actively fights the noise around you rather than just blocking it with a seal. There's also a transparency mode, and switching between ANC, transparency, and normal is done by tapping the function button four times — so you can hold a quick conversation without pulling the buds out.
Battery is the other big story. GNMN rates single-charge playback at up to 8 hours, and the charging case pushes total playback to as much as 96 hours. The case has a dual LED display that shows the battery level of both the case and the buds in real time, and it charges over USB-C. Audio comes from a 16mm driver with a large chamber design that the brand says balances air pressure to reduce sound loss, and the in-ear structure adds passive isolation on top of the ANC.
This is the pick for someone who wants the most control over their listening environment. The IPX7 rating and soft ear hooks mean sweat and rain aren't a dealbreaker, so it works for training too — but the real reason to choose it is the noise cancellation and the enormous case capacity. You should skip it if you dislike in-ear fit, since it's an in-ear design with ear hooks rather than an over-ear hook. It also ships with S/M/L eartips, and GNMN specifically notes smaller ears should go with the S tips, so fit tuning matters here.
The PEFUPEW C605 takes a different angle: connection quality and comfort. It uses Bluetooth 5.4, which the brand says increases connection speed substantially over the previous generation, with a rated audio delay of just 40 milliseconds and a stable range up to 15 meters. For anyone who has dealt with laggy audio while watching video or gaming on a phone, that low-latency figure is the number to care about.
Sound comes from a 14.2mm dynamic driver paired with a three-layer composite diaphragm, and PEFUPEW rates the bass enhancement at 43% while claiming reduced distortion. Calls are handled by four ENC microphones that the brand says eliminate up to 80% of background noise — useful on a busy street, in a gym, or in an open office. Note that PEFUPEW's noise control is listed as passive noise cancellation and sound isolation, so it relies on the seal and the over-ear hook rather than active circuitry.
Battery is rated up to 48 hours total, with up to 8 hours per charge at 50% volume and 4–5 additional charges from the case. Charging is USB-C, with a 1.5-hour charge time and a dual LED display on the case. The fit is the standout: an over-ear hook design that the brand says reduces ear canal pressure and suits long-term wear. It ships with silicone earplugs in S/M/L. Choose this if you want a comfortable, stable hook fit and the newest Bluetooth standard. Skip it if active noise cancellation is non-negotiable for you.
• Best for active noise cancellation → GNMN Active Noise Cancelling. Up to 45dB ANC depth plus a transparency mode is a genuinely different capability than passive isolation.
• Best for total battery life → GNMN Active Noise Cancelling. Up to 96 hours with the case versus up to 48 hours on the PEFUPEW.
• Best for call clarity in noisy places → PEFUPEW Earbuds. Four ENC microphones with a rated 80% background noise reduction is the more call-focused spec.
• Best for the newest Bluetooth connection → PEFUPEW Earbuds. Bluetooth 5.4 with a rated 40ms latency and up to 15 meters of range.
• Best for long-wear comfort → PEFUPEW Earbuds. The over-ear hook is designed to reduce ear canal pressure, which matters over multi-hour sessions.
• Best for flying, commuting and open offices → GNMN Active Noise Cancelling. The ANC and transparency modes are built for exactly these environments.
• Best for gym and outdoor sessions → either, but for different reasons. GNMN gives you IPX7 and in-ear hooks; PEFUPEW gives you IP7 and lighter over-ear hooks.
• Best for driver size → GNMN Active Noise Cancelling. A 16mm driver versus the 14.2mm unit on the PEFUPEW.
If I were buying for myself and my days involved flights, trains, or a noisy workspace, I'd go with the GNMN Active Noise Cancelling. In my opinion, the up-to-45dB ANC, the transparency mode, and the up-to-96-hour case make it the more capable all-rounder, and the IPX7 rating means it still handles a sweaty workout. I'd pick the PEFUPEW Earbuds instead if comfort and connection were my top two priorities — the over-ear hook and Bluetooth 5.4 are real advantages for long gym sessions and lag-free video. Both are solid choices; it comes down to whether you want to silence the room or barely feel the buds.
Yes, based on the specs. GNMN lists active noise cancellation with up to 45dB depth plus a transparency mode. PEFUPEW lists passive noise cancellation and sound isolation, meaning it blocks sound through fit and seal rather than active circuitry.
GNMN rates up to 8 hours per charge and up to 96 hours total with the case. PEFUPEW rates up to 8 hours per charge at 50% volume and up to 48 hours total, with the case providing 4–5 additional charges.
PEFUPEW uses Bluetooth 5.4 with a rated 40ms latency and up to 15 meters of range. GNMN uses Bluetooth with auto-pairing and a low-latency, stable signal but doesn't specify a version in the data. On paper, PEFUPEW's 5.4 spec is the newer standard.
Yes. GNMN carries an IPX7 waterproof rating, and PEFUPEW carries IP7. Both are positioned for sports, running, and sweaty activity, and both use soft ear hooks to stay put.
