How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a featherweight wired ear-fit pair that stays out of your way and never needs charging, choose Audio Technica ATH-EQ300M; if you need open-ear wireless earbuds with a charging case, long battery life and sweat resistance for running and gym work, choose otinsile M97.
• Audio Technica ATH-EQ300M — biggest strength: a genuinely tiny wired design. At 20 g (0.7 oz) with an ultra-thin housing and a 1.2 m cord, it's built for people who want sound without bulk, batteries or pairing.
• Audio Technica ATH-EQ300M — biggest trade-off: it's wired and passive. No Bluetooth, no charging case, no water-resistance rating, and noise control is listed as "None."
• otinsile M97 — biggest strength: open-ear wireless freedom with a 50-hour total battery figure, a 10-minute quick charge that adds 2 hours, Bluetooth 6.0 and an IPX5 rating.
• otinsile M97 — biggest trade-off: the open design deliberately lets outside sound in, so bass won't hit like a sealed in-ear model, and you're dependent on the charging case.
• Pick the ATH-EQ300M if you want a plug-in-and-go wired pair for desk work, commuting or casual listening.
• Pick the otinsile M97 if you're running, cycling or training and want awareness of your surroundings plus all-day wireless playtime.
The ATH-EQ300M is a wired, ear-fit headphone with a 3.5 mm jack. The spec sheet leads with the housing: it's ultra thin and weighs just 20 g, which is the whole point of this design. Nothing clamps down on your ears, nothing sits deep in your canal, and nothing needs to be charged. You plug it in and it works. That simplicity is the product.
Audio quality is framed around a dynamic driver with a 16 Hz to 24,000 Hz frequency range and 20 ohm impedance. That low impedance figure matters for everyday buyers: it means the ATH-EQ300M is easy to drive from a phone, a laptop or a basic player without a headphone amp. The 24,000 Hz top end covers the full audible range for most listeners. The description also emphasizes clear playback with less strain on the ears — consistent with the lightweight, ear-fit approach rather than a sealed, isolating one.
otinsile M97: Who It's For
The otinsile M97 is an open-ear, clip-on wireless earbud. The design is a C-shaped hook that clips over the ear instead of plugging into it, and at roughly 4 g per bud it's about as light as this category gets. Open-ear means your canal stays unobstructed, so you keep 360° awareness of traffic, other people and your surroundings while audio plays. For runners, cyclists and anyone training outdoors, that's the core reason to choose this shape over sealed earbuds.
The numbers back up the outdoor use case. The M97 carries an IPX5 waterproof rating, which covers sweat and rain, so gym sessions and wet-weather runs are within its stated comfort zone. Bluetooth 6.0 handles the connection with a range listed at 10 meters (about 33 ft), and the driver is a 12 mm dynamic unit with a 20 Hz to 20,000 Hz range and 80 ohm impedance. The sound profile is openly described as clear mids and highs with a natural soundstage rather than deep, sealed-in bass — the brand itself notes the open design doesn't create an isolated chamber, so expect less low-end thump than a traditional in-ear.
Battery is the headline. You get 6 hours of continuous playtime per charge and 50 hours total with the charging case, which holds a 250 mAh battery and recharges in about 2 hours. A 10-minute quick charge delivers roughly 2 extra hours — genuinely useful when you're heading out the door and realize you forgot to plug in. Touch controls handle playback, and there's a one-year warranty listed. Who should buy it: runners, cyclists, gym-goers and glasses wearers who want zero ear pressure plus situational awareness. Who should skip it: anyone who wants maximum isolation, wired dependability, or bass that hits like a sealed in-ear.
• Best for running and outdoor training → otinsile M97. IPX5 sweat/rain protection plus open-ear awareness is exactly the combination outdoor athletes need.
• Best for battery and wireless freedom → otinsile M97. 6 hours per charge, 50 hours with the case, and a 10-minute quick charge for 2 extra hours.
• Best for zero-maintenance listening → Audio Technica ATH-EQ300M. No charging, no pairing, no case — just a 3.5 mm plug.
• Best for all-day comfort and low weight → Audio Technica ATH-EQ300M. At 20 g with an ultra-thin housing, it's built to disappear on your head.
• Best for glasses wearers → otinsile M97. The C-shaped hook sits outside the ear, so there's no pressure against frames.
• Best for isolation → neither, strictly speaking. The ATH-EQ300M lists no noise control, and the M97's open design intentionally lets sound in. If isolation is your priority, look at sealed in-ears instead.
• Best for easy phone/laptop driving → Audio Technica ATH-EQ300M. Its 20 ohm impedance is undemanding; the M97's 80 ohm figure asks a bit more of the source.
• Best for bass depth → neither by design. The M97 openly trades bass for clarity and awareness; the ATH-EQ300M is tuned for clear, low-strain playback rather than thump.
In my opinion, the honest answer depends on how you'll use them, but if I had to pick one for the average buyer, I'd lean toward the otinsile M97. The 50-hour total battery, IPX5 rating, Bluetooth 6.0 and 4 g open-ear fit cover more real-world scenarios — workouts, commutes, calls and outdoor time — without asking you to think about anything but the case. That said, I'd recommend the Audio Technica ATH-EQ300M without hesitation for anyone who wants a wired, no-fuss pair for desk work and casual listening, or who simply doesn't want another device to charge. Different tools, different jobs.
No. It's a wired headphone with a 3.5 mm jack and a 1.2 m cord. If you need Bluetooth, the otinsile M97 is the wireless option here.
It carries an IPX5 waterproof rating, which the specs describe as protection against sweat and rain. That's suitable for runs and gym sessions; it isn't a claim of full submersion protection.
Neither is a bass-first design. The M97's own description admits the open design produces less bass than sealed in-ears and focuses on clear mids and highs. The ATH-EQ300M is tuned for clear, low-strain playback.
Decide by lifestyle, not by spec sheet: if you want wireless, sweat resistance and a charging case for training, take the otinsile M97. If you want a wired, lightweight, charge-free pair for desk and casual listening, take the Audio Technica ATH-EQ300M. For current pricing on either, check the price button on this page.
