If you want a low-latency wireless gaming setup for VR headsets and consoles, choose ZAROBO SOOMFON VR; if you need all-day open-ear earbuds for running, cycling and calls, choose Ugreen HiTune S3.
These two look similar on a shelf — both white, both wireless, both with a charging case — but they are built for completely different jobs. One is a dedicated gaming dongle-and-earbud combo aimed at latency. The other is a lifestyle open-ear pair built around comfort and staying aware of your surroundings. Pick the wrong one and you will be frustrated within a week, so let's break down exactly who each is for.
• ZAROBO SOOMFON VR biggest strength: 2.4GHz wireless via an included USB-C dongle, which is the connection type that matters when you game on Quest 2, PS5, PC or Steam Deck. The spec sheet lists 16ms latency.
• ZAROBO SOOMFON VR biggest trade-off: It is a gaming accessory first. There is no Bluetooth listed, so it pairs with what the dongle plugs into — not with your phone on a walk.
• Ugreen HiTune S3 biggest strength: Comfortable open-ear C-shape clip design at 5.3g per bud, Bluetooth 5.4, IPX5 water resistance and up to 30 hours of total playtime.
• Ugreen HiTune S3 biggest trade-off: The open-ear fit means less isolation by design, the max size is 2.5 cm so larger ears may not fit, and there is no companion app — touch control only.
• Who each pick is for: ZAROBO is for someone plugging a dongle into a headset or console and wanting the audio to keep up with fast motion. Ugreen is for someone who wants earbuds that stay put while running, driving or cycling and still let traffic and voices through.
The SOOMFON VR (model G10) is a wireless gaming earbud set with a very specific trick: it ships with a USB-C dongle and connects over 2.4GHz wireless rather than Bluetooth. That detail is the whole reason to buy it. On a spec sheet, 2.4GHz with an included dongle is the setup you want when latency is the enemy — think fast-turning VR games on Quest 2 or Quest Pro, or a PS5, PS4 or Steam Deck session where audio that lags behind the picture ruins the illusion. The listed audio latency is 16ms, which is the lowest number in this comparison, and it is the number that matters most for gaming.
Inside, you get a 10mm dynamic driver with a 20Hz–20,000Hz frequency range, which is a normal, sensible full-range tuning for game audio and general listening. The buds are in-ear with a rounded tip shape, so you get a plugged-in feel and some passive noise blocking — helpful when you are trying to hear footsteps or dialogue over a fan or a room full of noise. Controls are touch-based with volume control, and the set is white with a white plastic charging case.
Battery is the honest compromise. The earbuds are listed at 8 hours of average life and the case adds up to 24 hours more, with a 90-minute charge time. That is fine for a gaming session or an evening of play, but it is not an all-day-outdoors number.
Who should buy it: anyone whose main use is VR, console or handheld gaming and who wants the lowest latency they can get from a dongle-based setup. Who should skip it: commuters, runners and people who mostly listen from a phone over Bluetooth. There is no Bluetooth listed here, and the case capacity of 24 hours trails the Ugreen. If your day is podcasts and phone calls, this is the wrong tool.
The Ugreen HiTune S3 is an open-ear clip design, and Ugreen describes the fit as a C-shape that clips onto the ear edge and adjusts to your ear shape. At 5.3g per bud, that is genuinely light, and the point of the open-ear format is aural awareness — you hear your music and the world at the same time. For cyclists, hikers and runners, that is a safety feature, not a compromise. Ugreen even frames it that way in its own notes.
Audio runs through 12mm drivers, larger than the ZAROBO's 10mm, for a balanced sound signature with what Ugreen calls deep bass. The impedance is listed at 16 ohm, which is easy to drive. Call quality gets AI noise cancelling for voice pickup, and Ugreen claims the design reduces sound leakage by 98%. The enclosure uses thermoplastic elastomer and titanium alloy, which is a durable-feeling material combination for something you clip to your ear. The connection is Bluetooth 5.4 with a listed 10-meter range and a 0.08-second low delay in Game Mode — 80ms in the audio spec field, and worth knowing that is higher than the ZAROBO's 16ms.
Battery is where the S3 runs away with it: up to 7.5 hours per charge and 30 hours total, with USB-C fast charge giving roughly 120 minutes of use from a 15-minute top-up. A full charge takes about 2 hours. IPX5 water resistance covers sweat and rain, which matters if you run or commute in bad weather, and the nano-coated components are meant to survive it. There is a 2-year manufacturer warranty listed, too.
Two trade-offs to be straight about. First, the maximum size is 2.5 cm, so Ugreen itself warns these may not fit larger ears — try to know your ear size before committing. Second, there is no dedicated app; control is touch-only. And because it is open-ear, you will not get the isolation the ZAROBO's in-ear fit provides. That is the deal you make for awareness.
Who should buy it: runners, cyclists, drivers, gym-goers and anyone who wants earbuds they can leave in for hours and still hear a car or a colleague. Who should skip it: people who want to block out the world, and anyone gaming on a VR headset where 80ms of latency and a Bluetooth-only connection would be a step backward.
• Best for VR and console gaming → ZAROBO SOOMFON VR. The 2.4GHz dongle connection and 16ms latency are purpose-built for Quest 2, Quest Pro, PS5, PS4, Steam Deck, PC and Switch.
• Best for battery life → Ugreen HiTune S3. 30 hours total versus 24 hours on the ZAROBO, plus a fast charge that gives 120 minutes from 15 minutes plugged in.
• Best for running, cycling and driving → Ugreen HiTune S3. The 5.3g open-ear clip and IPX5 rating are designed for sweat, rain and staying aware of traffic.
• Best for low latency in general → ZAROBO SOOMFON VR. 16ms listed versus 80ms / 0.08s Game Mode on the S3. For twitchy, fast-motion content, lower wins.
• Best for call clarity in noisy places → Ugreen HiTune S3. AI noise cancelling for voice pickup and a claimed 98% reduction in sound leakage are aimed squarely at calls and podcasts.
• Best for blocking out background noise → ZAROBO SOOMFON VR. The in-ear rounded-tip fit seals your ear; open-ear by definition does not.
• Best for fitting unusual or larger ears → ZAROBO SOOMFON VR. Ugreen explicitly notes a 2.5 cm maximum size that may not suit larger ears.
• Best for phone-first listeners → Ugreen HiTune S3. Bluetooth 5.4, 10-meter range and no dongle required. The ZAROBO lists no Bluetooth.
If I were buying for myself, I would take the Ugreen HiTune S3 — but only because my daily listening is walking, commuting and calls, and the 30-hour battery, IPX5 rating and 5.3g open-ear fit line up with that life. If gaming were my priority, I would flip without hesitation: the ZAROBO SOOMFON VR's 2.4GHz dongle and 16ms latency are exactly the specs that matter in VR and on a console, and no amount of battery life fixes lag in a headset. Decide which of those two people you are, and the choice makes itself.
FAQ
It connects over Bluetooth 5.4 with a 10-meter range, so it will pair with Bluetooth-capable devices, but its listed 80ms latency and open-ear design make it a poor fit for VR where the ZAROBO's 16ms and sealed in-ear fit are the better match.
The Ugreen HiTune S3. Ugreen lists up to 7.5 hours per charge and 30 hours total, plus a 15-minute fast charge for about 120 minutes of use. The ZAROBO lists 8 hours in the buds and up to 24 hours with the case, with a 90-minute charge time.
I do not quote prices here — they change often, so check the current price on Amazon using the button on this page. On specs alone, the ZAROBO is the better value if you game in VR or on a console, and the Ugreen is the better value if you want long battery, waterproofing and open-ear comfort for everyday use.
