How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want an open-ear clip design that keeps you aware of traffic while still fighting background noise, choose Ugreen ClipBuds Pro Open; if you need maximum battery life and the deepest noise cancellation for long flights and office focus, choose havit Space S1.
• Ugreen ClipBuds Pro Open — biggest strength: an open-ear clip-on build with adaptive ANC, Hi-Res LDAC audio, spatial sound and a 6-mic call array, so you get awareness and clarity in one package.
• Ugreen ClipBuds Pro Open — biggest trade-off: it's tuned around short, active sessions rather than marathon listening, and the open design physically lets some sound in.
• havit Space S1 — biggest strength: hybrid adaptive ANC rated up to -45dB paired with up to 100 hours of playtime, which is exactly what travel and long workdays demand.
• havit Space S1 — biggest trade-off: it's an over-ear headphone at 280 g, so it's bulkier and more isolating than a clip-on, and it blocks your ears rather than leaving them open.
• Pick Ugreen ClipBuds Pro Open if you run, cycle, commute through city traffic or want to hear your surroundings.
• Pick havit Space S1 if you fly, work in a noisy office or just want to charge your headphones as rarely as possible.
The Ugreen ClipBuds Pro Open is built around a specific idea: put sound near your ear without plugging it. The C-shaped bridge uses a 0.6mm titanium memory wire to hold the bud on the edge of your ear, so your ear canal stays open. In everyday terms, that means you can hear a car behind you on a run, catch a train announcement, or answer a colleague without pulling an earbud out. For anyone who's ever felt uneasy wearing sealed buds while cycling, that design choice is the whole point.
The feature list doesn't stop at "open," though. Ugreen adds adaptive ANC that adjusts to your environment, which is unusual for this style of earbud — normally open designs just accept the noise. It also carries Hi-Res Audio certification with 96kHz/24-bit support, LDAC and Bluetooth 6.0, dual magnetic drivers for bass, spatial audio for movies and podcasts, and six microphones with AI wind-noise reduction for calls. Battery is 7 hours per charge and 32 hours with the case, and a 10-minute top-up gives you 2 hours. IPX5 means sweat and light rain are fine.
Who should skip it: if you want to disappear into a bubble of silence on a 12-hour flight, an open-ear clip is the wrong tool. It's also not for people who prefer over-ear cushioning for long desk sessions — 7 hours per charge is fine for a workout or a commute, less so for back-to-back workdays without the case.
havit Space S1: Who It's For
The havit Space S1 takes the opposite approach: seal the ear, cancel the world, and keep going for days. It's an over-ear headphone with hybrid adaptive ANC rated to cut up to -45dB, and it adjusts that cancellation automatically based on what's around you. There's also a transparency mode for when you do want to hear the person at the gate or the barista calling your name. For planes, subways and open-plan offices, that combination is the classic recipe — and havit leans into it hard.
Battery is the headline number: up to 100 hours with ANC off, 72 hours with ANC on. That's measured in days, not hours, and it changes how you use headphones — you stop thinking about charging entirely on a week-long trip. The 40mm dynamic drivers and LHDC high-resolution audio support cover the sound side, with a bass-forward tuning that suits movies and commuting playlists. Five microphones with ENC handle calls, Bluetooth 6.0 covers the connection, and dual-device pairing lets you jump between a laptop call and your phone without re-pairing. The app gives you EQ control.
A couple of practical details stand out. There's a 3.5mm jack, so you can go wired — and per the spec sheet, wired mode still works with ANC active, which is a nice fallback on a plane's entertainment system. It ships with a protective case, which matters for a 280 g headphone. The trade-off is exactly what you'd expect: it's heavier and more isolating, so it's not the pick for running, cycling or anything where you need to hear traffic. It's also button-controlled rather than touch, which some people prefer and others don't.
Who should buy it: frequent flyers, remote workers, students in loud dorms, and anyone who wants one pair of headphones to cover a whole trip or workweek on a single charge.
Side-by-Side: Which Should You Choose?
• Best for battery life → havit Space S1. Up to 100 hours (ANC off) / 72 hours (ANC on) versus 7 hours per charge and 32 hours with the case on the Ugreen.
• Best for situational awareness → Ugreen ClipBuds Pro Open. The clip-on, open-ear design leaves your canal unobstructed; the havit seals your ears.
• Best for maximum noise cancellation → havit Space S1. Hybrid adaptive ANC rated up to -45dB is a step beyond the Ugreen's adaptive ANC, which is impressive for an open-ear bud but still open by design.
• Best for running, cycling and gym → Ugreen ClipBuds Pro Open. IPX5, titanium wire clip, light silicone/PU build; the havit is a 280 g over-ear with no water-resistance claim in the sheet.
• Best for flights and long workdays → havit Space S1. Over-ear cushioning, a protective case, a wired 3.5mm fallback and multi-day battery.
• Best for calls in windy or busy places → Ugreen ClipBuds Pro Open. Six mics with AI wind-noise reduction and directional sound-field tech to cut leakage.
• Best for Hi-Res wireless detail on the go → Ugreen ClipBuds Pro Open. LDAC plus Hi-Res certification at 96kHz/24-bit in a tiny clip-on.
• Best for a wired option → havit Space S1. It has a 3.5mm jack; the Ugreen is wireless-only with no jack.
In my opinion, these two barely compete — they solve different problems, and the right answer is whichever problem is yours. If I had to pick one, I'd buy the havit Space S1 for a single do-everything pair, because 100 hours of playtime, up to -45dB adaptive ANC and a wired fallback cover travel, office and home without babysitting a charger. But I'd recommend the Ugreen ClipBuds Pro Open without hesitation to anyone whose listening happens outdoors or on the move, where hearing your surroundings matters more than total silence. Buy for your environment, not for the spec sheet.
The Ugreen. It's an open-ear clip-on with IPX5 water resistance and a titanium-wire fit that's designed to stay put, while the havit is a 280 g over-ear headphone with no water-resistance claim listed.
Much longer. havit lists up to 100 hours with ANC off and 72 hours with ANC on. Ugreen lists 7 hours per charge and 32 hours total with the case, plus a 10-minute quick charge for 2 hours of use.
No. Ugreen has adaptive ANC and sits open at the ear edge, so it reduces low-frequency noise but still lets sound in. havit uses hybrid adaptive ANC rated up to -45dB with a sealed over-ear fit, so it isolates far more.
Both claim Hi-Res wireless audio — Ugreen with LDAC at 96kHz/24-bit and dual magnetic drivers, havit with LHDC and 40mm dynamic drivers. The Ugreen is more detail-focused in an open design; the havit leans bass-heavy in a sealed one. Check the current price on Amazon and match the tuning to your taste.
