If you want discreet, low-profile earbuds for study, choose Xmenha Flat Sleep Mini; if you need cushioned over-ear headphones you can fold and carry, choose UNVO B35S. The Xmenha package includes both flat sleep earbuds and a separate mini pair, while the UNVO takes a more familiar headband-style approach.
For quiet desk sessions or side sleeping, I’d lean toward Xmenha. For a larger, cushioned fit and easier packing, I’d choose UNVO.
• Xmenha Flat Sleep Mini strength: Two pairs of earbuds, including an ultra-flat, non-in-ear sleep design; trade-off: battery life is listed as four hours.
• UNVO B35S strength: Cushioned over-ear cups and a foldable design; trade-off: it is a head-worn option, not a compact earbud pair.
• Xmenha is for listeners who want discreet earbuds for study, small-ear-friendly mini buds, or a flat design for side sleeping.
• UNVO is for listeners who prefer cushioned cups, a foldable frame, and a headphone shape for desk use or travel.
• For an unobtrusive fit, choose Xmenha; for over-ear coverage and portability, choose UNVO.
Xmenha’s central advantage is choice within one package. It includes a pair of tiny mini earbuds and a second pair of flat sleep earbuds. The mini pair is described as lightweight, with each earbud weighing 0.1 ounces, and its shape is intended to sit discreetly in the ear. The separate sleep pair has a flat, non-in-ear design aimed at reducing pressure when lying on your side.
That makes Xmenha a strong fit for someone who dislikes a headband or wants a low-profile option for study. The mini earbuds may appeal if you have small ear canals or want something less conspicuous while listening at a desk. For anyone searching for the best open ear earbuds for study, the sleep pair’s non-in-ear construction is the relevant feature: it avoids inserting into the ear canal. The listing also describes both pairs as Bluetooth earbuds, with the mini pair identified as “mini” and the flat pair as “MD” when pairing.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
There are limits to consider. Battery life is listed at four hours, and charging takes 1.5 hours. That is a specific trade-off for longer sessions: you may need to plan around charging rather than expect an uninterrupted day of listening. The mini pair also uses a smaller driver than the larger flat sleep earbuds, according to the product description, so Xmenha itself acknowledges an audio trade-off between compactness and a larger speaker. Choose another style if you want cushioned ear cups or prefer not to manage two separate pairs.
The UNVO B35S is the simpler choice if you want headphones that sit over the ears rather than small earbuds. Its cushioned cups are described as comfortable for extended wear and as helping to block ambient noise. The foldable construction is meant to make the headphones easier to store and carry, so the design may suit a study setup that moves between a desk, a bag, and another listening spot.
For learners who prefer a visible, head-worn fit, that can be an appealing alternative to in ear headphones for study. The product is also presented for gaming, sports, travel, and music listening. Bluetooth connectivity is listed, and the product information also mentions a 3.5 mm and Type-C headphone jack. A 10-millimeter dynamic driver, 32-ohm impedance, and 16-millisecond audio latency are specified, though those figures alone do not establish how the headphones will sound in every situation.
The main trade-off is the form factor. The B35S is not the discreet, flat earbud option in this comparison, and its over-ear cups may not suit someone who wants a barely noticeable fit or sleeps on their side. Its wireless Bluetooth version is listed as 5, while Xmenha lists version 5.3. The B35S battery charge time is listed as two hours, but the sheet does not specify battery life, so there is no sound basis for claiming it lasts longer than Xmenha.
• Best for a low-profile fit during study → Xmenha Flat Sleep Mini. Its mini earbuds are described as small and discreet.
• Best for side sleeping → Xmenha Flat Sleep Mini. The separate sleep earbuds have a flat, non-in-ear design intended to reduce pressure against the ear.
• Best for cushioned over-ear coverage → UNVO B35S. Its padded cups are designed for an over-ear fit and are said to help block ambient noise.
• Best if you want two earbud styles in one package → Xmenha Flat Sleep Mini. It includes both mini earbuds and flat sleep earbuds, with separate Bluetooth names.
• Best for folding into a bag → UNVO B35S. Its over-ear construction folds for storage and portability.
• Best when a stated battery runtime matters → Xmenha Flat Sleep Mini. Its listed average battery life is four hours; UNVO’s sheet gives a charge time but no runtime.
• Best for a wired connection option → UNVO B35S. Its product information lists 3.5 mm and Type-C jacks, alongside Bluetooth connectivity.
• Best for someone avoiding an in-ear fit → Xmenha Flat Sleep Mini. The sleep pair is specifically described as non-in-ear, while UNVO uses cushioned over-ear cups.
If you’re comparing the best over ear headphones for study with earbuds, the core question is whether you want ear cups around your ears or a smaller listening setup. UNVO is the direct match for the first preference. Xmenha is the more flexible fit if you prefer earbuds, especially if side sleeping or a discreet profile matters.
Neither design is automatically right for every study space. Over-ear cups can feel more substantial and may help block ambient noise, while a compact earbud setup avoids wearing a headband. Xmenha’s two-pair format is useful if you want different shapes for different moments, but the listed four-hour battery life is worth weighing against your planned session length. UNVO folds for transport, but its battery runtime is not specified here, so I wouldn’t assume it is the better choice for a long stretch away from charging.
My Verdict
I’d choose Xmenha Flat Sleep Mini for study because it offers both a discreet mini pair and a flat, non-in-ear sleep pair.
The four-hour listed battery life is a real limitation, so I’d choose UNVO instead if cushioned cups and a foldable frame matter more.
For my study-focused pick, though, Xmenha’s two distinct earbud styles make more sense.
For a discreet earbud fit, Xmenha is the more direct choice and includes two earbud styles. UNVO suits someone who prefers cushioned over-ear cups. The better fit depends on whether you want earbuds or a head-worn design.
Xmenha includes flat sleep earbuds described as non-in-ear and designed with side sleeping in mind. The UNVO B35S is an over-ear headphone, so it does not have the same flat earbud design.
The listed information gives Xmenha an average battery life of four hours. UNVO’s sheet lists a two-hour charge time but does not give a battery runtime, so the available specifications do not establish that it lasts longer.
The UNVO B35S product information lists 3.5 mm and Type-C headphone jacks as well as Bluetooth connectivity. Xmenha is listed as wireless Bluetooth and has no headphone jack.
