How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life, a higher waterproof rating and a bigger driver for bass-heavy listening, choose Htcmf Open Ear Earbuds; if you need lighter earhooks that play nicer with glasses, faster recharging and a built-in translation app for travel, choose HAUSBELL Open Ear.
• Htcmf Open Ear Earbuds — biggest strength: 90 hours of total playtime with an LED battery display on the case, plus an IPX7 water-resistance rating and a large 16.4mm dynamic driver.
• Htcmf Open Ear Earbuds — biggest trade-off: 9 hours of playback per charge is shorter than the HAUSBELL's single-charge figure, and the case itself takes 9 hours to charge.
• HAUSBELL Open Ear — biggest strength: 10 hours on a single charge, a 45-minute recharge time, Bluetooth 6.1, and soft silicone earhooks explicitly designed around glasses wearers.
• HAUSBELL Open Ear — biggest trade-off: IPX5 water resistance is a step below IPX7, and the claimed 80-hour total depends on a smaller 14.2mm driver than the Htcmf's.
• Who each pick is for: Htcmf suits heavy sweaters, long-haul users and bass lovers who want the toughest moisture protection; HAUSBELL suits glasses wearers, frequent flyers and anyone who wants translation tools in the same earbuds.
The Htcmf O8 leads with endurance. You get up to 9 hours of playback on a single charge, and the charging case stretches that to roughly 90 hours total. That gap matters in practice: a single charge covers a long training block or a full workday, and the case covers weeks of commuting without hunting for an outlet. The LED display on the case shows remaining battery and charging status, so you are not guessing before you leave the house. In my opinion, that display is the most underrated feature here — it removes the small daily anxiety of a dead pair of buds.
The durability story is the other selling point. An IPX7 rating means resistance to sweat and moisture, which is a meaningful step up from the more common IPX5 you see on sport earbuds. If you run in humid heat, ride in drizzle, or finish a session genuinely drenched, that rating is the difference between "probably fine" and "rated for it." The 16.4mm dynamic driver is also notably large for this category, which is where the "vibrant bass" claim in the spec sheet comes from — bigger drivers move more air, and that generally translates to fuller low end. Bluetooth 5.3 with a 33-foot range and auto-pairing when you open the case keeps the setup friction low, and the open-ear hook design keeps traffic, cyclists and conversation audible while you listen.
HAUSBELL Open Ear: Who It's For
The HAUSBELL Q16 is built around fit and travel convenience. The headline is 10 hours of playback on one charge, plus 70 more in the case for a nominal 80 hours total. But the number I find more interesting is the recharge time: 45 minutes. That is fast enough that a short break — a shower, a coffee, a layover — can put you back in business. Compare that to a 9-hour case charge and the difference in daily rhythm is real, especially on trips where you are rotating between outlets and power banks.
The earhooks are silicone and described as soft and flexible, molding to the ear's natural curve for a bounce-free fit. The listing explicitly calls out comfort for glasses wearers, which is a genuinely useful detail — temple arms and rigid hooks are a common source of pressure and slipping, and a flexible hook design is the usual fix. Bluetooth 6.1 is listed, along with a 15-meter (roughly 49-foot) range, and the touch controls are described as fingerprint and touch based. IPX5 means it handles heavy perspiration and light rain, which covers most gym and commuting scenarios, though it is not the same grade of protection as IPX7.
Then there is the oddity: a companion app with 165-language translation, no subscription required. The spec sheet frames it as a basic backup for travel or simple conversations, and that is exactly how I would treat it — a nice bonus, not a reason to buy on its own. The package includes two AI translation headphones, a wireless charging case, a cable and manuals, and the brand lists a one-year warranty.
Who should buy it: glasses wearers, frequent travelers, commuters and anyone who values fast top-ups over maximum per-charge runtime. Who should skip it: if you sweat heavily outdoors or ride in real rain, IPX5 is the weaker claim here, and the 14.2mm driver is smaller than the Htcmf's if deep bass is your priority.
Side-by-Side: Which Should You Choose?
• Best for fastest recharging → HAUSBELL Open Ear. A 45-minute charge time is a clear advantage over the Htcmf's 9-hour case charge.
• Best for sweat and rain resistance → Htcmf Open Ear Earbuds. IPX7 beats IPX5 when sessions get genuinely wet.
• Best for glasses wearers → HAUSBELL Open Ear. Silicone earhooks are specifically described as comfortable for glasses.
• Best for bass-forward listening → Htcmf Open Ear Earbuds. The 16.4mm driver is larger than the HAUSBELL's 14.2mm.
• Best for travel extras → HAUSBELL Open Ear. The 165-language translation app and two-headphone bundle add real utility on the road.
• Best for longer single sessions → HAUSBELL Open Ear. 10 hours per charge edges out the Htcmf's 9.
• Best for longer wireless reach → HAUSBELL Open Ear. A listed 15-meter range is wider than the Htcmf's 33 feet.
In my opinion, the Htcmf Open Ear Earbuds are the safer buy for most people shopping this category. The combination of IPX7 protection, a bigger 16.4mm driver and up to 90 hours of total playtime covers the two things open-ear buyers actually care about: surviving sweat and not dying mid-week. I would only switch to the HAUSBELL Open Ear if you wear glasses, travel often, or hate waiting on a charger — the 45-minute top-up, the flexible silicone hooks and the translation app are real advantages there. Both are open-ear designs with no active noise cancellation, so pick based on fit and durability, not on blocking out the world. Check the current price on Amazon before you commit, since pricing moves around.
The Htcmf carries an IPX7 water-resistance rating, while the HAUSBELL is rated IPX5. For heavy sweat or wet weather, the Htcmf's higher rating is the more protective choice. The HAUSBELL still handles perspiration and light rain.
The HAUSBELL plays up to 10 hours per charge versus about 9 hours on the Htcmf. Over a full case cycle, though, the Htcmf reaches roughly 90 hours total against the HAUSBELL's 80.
The HAUSBELL Open Ear is the one to look at — its silicone earhooks are described as comfortable for glasses wearers. The Htcmf sheet does not address glasses fit, so I would not assume it works as well.
Neither lists active noise cancellation; both are open-ear designs meant to keep you aware of your surroundings. The HAUSBELL includes a companion app with 165-language translation, while the Htcmf does not list an app.
