If you want lightweight, open-ear listening for glasses wearers, choose Kinglucky ClipFree Open-Ear Headphones; if you need a foldable, cushioned over-ear design, choose UNVO B35S. The main distinction is how they sit: Kinglucky clips onto the ear without plugging it, while UNVO covers the ears with padded cups. For a glasses-first choice, I’d lean Kinglucky; for a more enclosing fit, I’d choose UNVO.
• Kinglucky’s biggest strength: a 4.0-gram-per-side open-ear clip design that avoids an in-ear fit and is described as suitable for glasses. Trade-off: it does not cover the ears, so it won’t offer the same cushioned, enclosing feel as an over-ear headset.
• UNVO’s biggest strength: foldable over-ear construction with cushioned cups intended to help block ambient noise. Trade-off: the over-ear shape sits around the ears, which may be less convenient if your glasses’ arms compete for space.
• Kinglucky lists Bluetooth 5.4 and IP56 protection against sweat and light rain; UNVO’s listed Bluetooth version is 5.
• Kinglucky’s listed average battery life is 10 hours. UNVO’s sheet gives a two-hour charge time but no battery-life figure.
• Choose Kinglucky for lightweight open-ear listening and an ear-cuff look; choose UNVO for a foldable, cushioned design that covers the ears.
Kinglucky is the more natural fit if you dislike earbuds that sit inside the ear. Its clip-on design rests on the ear instead, and the stated weight is 4.0 grams per side. That light, open construction is particularly relevant for glasses wearers: there’s no conventional earbud body to push into the ear canal, and the design is specifically described as compatible with glasses. It also has detachable crystal accessories, giving it a more jewelry-like appearance than a standard audio device.

I’d consider Kinglucky if your priorities are glasses-friendly wear, a lightweight clip fit, and some protection for walks or workouts where sweat or light rain may be a factor. It is also the more distinctive option if you like the accessory-style design. Skip it if you specifically want padded cups around your ears, or if the detachable decorative pieces sound like extra items you would rather not manage. The crystal accessories need to be removed when storing the headphones in their case.
UNVO B35S takes the opposite approach. It uses a foldable over-ear design with cushioned ear cups, and its listed purpose spans learning, gaming, sports, travel, and music listening. That combination points toward someone who wants a headset-like fit and the convenience of folding the headphones for storage or carrying. The stated pink finish with silver accents also makes this a more visibly styled choice than a plain, understated headset.
The cushioned cups are described as helping block ambient noise, which may appeal if you want a more enclosing listening experience than open-ear clips provide. Bluetooth is listed, and the product information also lists a 3.5 mm and Type-C headphone connection. The specifications identify Bluetooth version 5 and a 33-foot Bluetooth range. UNVO’s sheet lists a two-hour charge time, but does not provide a battery-life figure, so there isn’t enough information here to compare its listening time directly with Kinglucky’s 10-hour figure.
For glasses wearers, the main question is physical fit. Over-ear headphones can be less comfortable if the ear cups press the glasses’ arms against your head. The product information gives no glasses-specific fit detail, so I wouldn’t assume the cushions solve that issue. Choose UNVO if a foldable over-ear shape and cushioned coverage matter more than keeping the ears open. If your glasses make ear-cup pressure a recurring problem, Kinglucky is the more clearly supported pick.

• Best for a stated battery-life figure → Kinglucky ClipFree Open-Ear Headphones. Its average battery life is listed as 10 hours; UNVO’s sheet lists charge time, not battery life.

For glasses wearers, I’d choose Kinglucky ClipFree Open-Ear Headphones. The lightweight clip-on design avoids the padded cups that can press on glasses arms, and it comes with a stated 10-hour average battery life plus IP56 protection for sweat and light rain. UNVO B35S makes more sense if you specifically want foldable, cushioned over-ear coverage. But for a glasses-first decision, Kinglucky is my pick.
They’re designed as lightweight clips that rest on the ear rather than conventional earbuds that go inside it. The product details specifically describe them as suitable for glasses, though individual fit can still vary.
Its cushioned over-ear cups are described as helping block ambient noise, while Kinglucky’s open-ear design leaves the ears uncovered. The provided information does not specify a noise-reduction measurement for either product.
Kinglucky lists an average battery life of 10 hours. UNVO lists a two-hour charge time but does not give a battery-life figure, so the available specifications don’t support a direct runtime comparison.
Kinglucky is the one with an open-ear design, glasses-specific fit language, and an IP56 rating described as suitable for sweat and light rain. UNVO’s listed design is foldable and over-ear; its provided details do not specify an IP rating.
