How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want featherlight open-ear comfort with the longest total battery and a fit that plays nicely with glasses, choose otinsile M97; if you need a smart touchscreen charging case, bigger drivers, and a higher waterproof rating, choose HJX Earbuds.
• otinsile M97 — biggest strength: a genuinely featherlight open-ear clip design (about 5g per bud, 4g listed in the item details) with a C-shaped hook, plus 50 hours of total playtime and 10-minute quick charge.
• otinsile M97 — biggest trade-off: the open design means you won't get the sealed-in bass punch of in-ear buds, and it carries only an IPX5 rating versus the HJX's IPX6.
• HJX Earbuds — biggest strength: a multifunctional LCD touchscreen charging case that handles music, volume, EQ modes, wallpapers, remote photos, alarms, and earbud-finding, backed by 16mm drivers and up to 60 hours total.
• HJX Earbuds — biggest trade-off: it's heavier and bulkier (about 50g for the buds and a 102g case with a 600mAh battery), so it's less of a "forget you're wearing it" pick than the M97.
• Who each is for: pick the otinsile M97 if you want the lightest, most unobtrusive open-ear fit for running, gym, and glasses wearers; pick the HJX Earbuds if you want a feature-rich touchscreen case and stronger bass hardware for workouts and travel.
The M97 is built around one idea: stay aware and stay comfortable. It's an open-ear, clip-on design, so nothing plugs your ear canal. For runners, cyclists, and anyone who needs to hear traffic or a training partner, that 360° environmental awareness is the whole point. The C-shaped hook is meant to sit securely across all ear sizes, and at roughly 5g per bud it's among the lightest open-ear options out there — which matters if you wear glasses, since there's no ear pressure building up over a long session.
On the audio side, otinsile fits 12mm dynamic drivers with what it calls Directional Sound Technology to cut leakage and improve voice pickup on calls. Be realistic here: otinsile itself notes you'll get less powerful bass than sealed in-ear models, because there's no isolated chamber. Instead you get clear mids and highs and a natural soundstage — great for podcasts, calls, and casual listening, less ideal if you're chasing thumping low-end.
Battery is where the M97 shines. You get 6 hours per charge and 50 hours total with the case, and a 10-minute quick charge buys about 2 extra hours — handy when you're rushing out the door. Bluetooth 6.0 covers a stable 33ft range with low latency for video and gaming, and IPX5 handles sweat and light rain.
Buy it if you prioritize all-day comfort, glasses-friendly wear, and awareness during outdoor workouts. Skip it if you want maximum bass, a smart case, or the highest water resistance.
The HJX Earbuds lead with a feature you rarely see: a multifunctional LCD touchscreen charging case. From that screen you can control music, adjust volume, switch EQ modes, set wallpapers, trigger a remote camera shutter, set alarms, and locate a misplaced earbud. If you like the idea of leaving your phone in your pocket — or your bag — during a workout or commute, that hands-free control is a real convenience, not a gimmick.
Sound leans bigger on paper: 16mm diaphragms versus the M97's 12mm, with HJX promising powerful bass and crisp highs. It also adds EQ modes you can switch on the case, so you can tune the sound to your taste. Bluetooth 5.4 keeps latency low and the connection solid within 33ft, and IPX6 means it shrugs off more water than the M97's IPX5 — a plus for heavy sweaters or rainy runs.
Battery runs up to 7 hours per charge and 60 hours total with the case, with Type-C flash charging. The trade-off is bulk: the buds are listed around 50g total and the case around 102g with a 600mAh battery, so it's a chunkier carry than the M97. The open-ear hooks and liquid silicone are designed for stability during movement, but the whole package is less "barely there."
Side-by-Side: Which Should You Choose?
• Best for all-day featherweight comfort → otinsile M97 (roughly 5g per bud, glasses-friendly C-hook).
• Best for smart, hands-free control → HJX Earbuds (touchscreen case with EQ, remote photo, alarm, earbud finder).
• Best for total battery life → HJX Earbuds (up to 60 hours total vs. the M97's 50 hours), though both list 50 hours in the battery specs.
• Best for quick top-ups on the go → otinsile M97 (10-minute quick charge for about 2 extra hours).
• Best for bigger bass hardware → HJX Earbuds (16mm drivers vs. 12mm).
• Best for water resistance → HJX Earbuds (IPX6 vs. IPX5).
• Best for environmental awareness and open-ear safety → either, but the M97's lighter build suits long outdoor sessions best.
• Best for travel and commuting → HJX Earbuds, if you don't mind the heavier case; otinsile M97 if portability wins.
If I had to pick one, I'd lean toward the otinsile M97 — but with a clear caveat. In my opinion, the M97 wins on the thing open-ear buyers care about most: comfort and a barely-there fit, especially for glasses wearers and long runs, plus the 10-minute quick charge is genuinely useful. That said, if you want the touchscreen case, more bass headroom, and IPX6, the HJX Earbuds are the better-rounded tech package. So: M97 for comfort-first runners; HJX for feature-first tinkerers. Check the current price on Amazon before deciding, since value depends on what each costs when you buy.
For pure comfort and awareness, I'd give the M97 the edge thanks to its ~5g open-ear clip and glasses-friendly hook. The HJX is also built for movement, but it's heavier and better suited to people who want its smart case features on a run.
On paper, the HJX has an edge for bass because of its 16mm diaphragms and EQ modes. The M97 uses 12mm drivers and openly trades deep bass for clarity and a natural, open soundstage. Pick the M97 for awareness and vocals; pick the HJX for fuller low-end.
Both are strong. The M97 gives 6 hours per charge and 50 hours total with a 10-minute quick charge for 2 extra hours. The HJX gives up to 7 hours per charge and 60 hours total with Type-C flash charging.
The HJX Earbuds carry an IPX6 rating, while the otinsile M97 is IPX5. Both handle sweat and rain, but the HJX offers slightly more protection for heavy workouts or wetter conditions.
