If you want long stated battery life and a sports-focused fit for exercise, choose CHENRUIDA M75; if you need a clip-on design that leaves your ear canal open, choose INSONIXN Open Ear Clip-On. For most exercise routines, I’d lean toward the M75 because its listed playtime is far more specific and its design is explicitly positioned for sports. The INSONIXN is the more distinctive pick for people who prioritize an ear-cuff fit and everyday awareness.
• CHENRUIDA M75: Its strongest point is the stated 80-hour total playtime with the charging case; its trade-off is that it has no detailed clip-on fit description.
• INSONIXN Open Ear Clip-On: Its ear-cuff design rests around the outer ear without entering the ear canal; its trade-off is that the supplied information gives no playtime figure.
• Choose the M75 if you want a sports-oriented open-ear option with a clear battery-life claim and mono listening as well as stereo.
• Choose the INSONIXN if you prefer an outer-ear clip, want to keep the ear canal open, and value a compact case and touch controls.
The M75 is the more straightforward choice for someone comparing open-ear headphones mainly for exercise. Its design is described as sports-oriented, and the stated fit is intended to remain secure during activity. The product information also lists a 7.08-gram item weight, which gives a concrete reference for buyers who want to avoid a bulky-looking set of headphones. The fit itself is described as open-ear, rather than an in-ear design.
Battery life is its clearest practical advantage on paper. CHENRUIDA lists up to eight hours of listening on one charge and up to 80 hours total when the charging case is included, with the earbuds used in rotation. That is a useful distinction: the total figure depends on returning an earbud to the case to recharge, not on listening for 80 uninterrupted hours. Bluetooth 6.0, a listed range of up to 35 feet, mono or binaural modes, and automatic power-on and connection when removed from the case round out the feature set.
I’d consider the M75 if your routine involves running, cycling, or workouts where a sports-focused fit and extended case-supported listening matter. I’d skip it if the specific clip-on shape is the main reason you’re shopping, or if you need published battery details for the INSONIXN’s more compact everyday style to compare directly. One-button control is also less elaborate than the INSONIXN’s listed touch functions, which include track changes and voice-assistant activation.

That shape also fits a routine built around moving between listening and paying attention to nearby activity. The open-ear design is intended to let you hear audio while keeping the ear canal open and staying more aware of your surroundings. The listed use cases include walking, commuting, working, studying, travel, and light workouts. Its touch controls cover playback, calls, track changes, and voice-assistant use, and its case is described as compact enough to carry in a pocket or bag.
I’d choose the INSONIXN if fit style and a less enclosed feel matter more than a long published battery claim. I would not pick it solely for demanding or extended exercise based on the available information: light workouts are mentioned, but there is no stated playtime figure or specific sports-fit claim comparable to the M75’s. The listing gives Bluetooth 6.0 and a 33-foot range, but does not provide a battery-life total.
• Best for exercise as the main use → CHENRUIDA M75. Its design is explicitly positioned for sports, running, and cycling, with a fit intended to stay in place during exercise.
• Best for an ear-cuff shape → INSONIXN Open Ear Clip-On. It rests around the outer ear rather than entering the ear canal.
• Best for stated battery life → CHENRUIDA M75. The claim is up to eight hours per charge and up to 80 hours with case-assisted rotation; the INSONIXN sheet provides no playtime figure.
• Best for glasses wearers or shoppers with small ears → INSONIXN Open Ear Clip-On. Those users are specifically called out in its fit description.
• Best for switching between stereo and one-ear listening → CHENRUIDA M75. Its listed binaural and mono modes let you use either both earbuds or one at a time.
• Best for touch functions beyond basic playback → INSONIXN Open Ear Clip-On. Its listed controls include calls, track changes, and voice-assistant activation.
• Best for pairing with the clearest stated wireless details → CHENRUIDA M75. It lists Bluetooth 6.0 and a range of up to 35 feet; the INSONIXN also lists Bluetooth 6.0, with a stated range of 33 feet.
• Best for everyday commuting and light activity → INSONIXN Open Ear Clip-On. Its description directly focuses on daily routines and carrying the compact case, while the M75 is the more exercise-oriented option.
These are open-ear products, so neither should be treated as a substitute for noise-isolating in-ear headphones. The INSONIXN description emphasizes awareness of surroundings. The M75 lists several noise-control terms in its product details, but the supplied information does not explain how those modes work or what they do in practice. I wouldn’t assume either model blocks environmental sound in a predictable way based only on those labels.
For shoppers searching for the best headphone for exercise, the decision turns on the activity and fit preference. The M75 has a stronger exercise-specific case from its stated sports design and battery information. The INSONIXN is the more clearly defined option for a clip-on shape and light workouts. If the wearer is a child, don’t assume that an adult-oriented fit will work: the M75 is described for adults, while the INSONIXN lists a kid-to-adult age range, but the available details do not provide a fit measurement. That makes the INSONIXN the more directly relevant candidate for someone searching for the best kids headphones for exercise, though its stated use case is light workouts rather than intensive sports.
Charging speed is another place where the distinction matters. The M75 lists a 1.5-hour battery charge time, while the INSONIXN lists a one-hour charge time. Those are charge-time figures, not a promise of a particular amount of listening after a quick top-up. Neither sheet specifies a rapid-charge feature or how much playback a short charge provides. So if you’re looking for a fast charging headphone for exercise, the INSONIXN has the shorter listed charge time, but it does not have a published playtime figure to put that speed in context.
I would buy the CHENRUIDA M75 for exercise because its sports-oriented fit and stated case-supported 80-hour total playtime make the more complete case for regular workouts. I also like that it supports mono listening, which can be useful when I want one earbud in use at a time. The INSONIXN is my pick if the ear-cuff shape, glasses-friendly positioning, or open-ear awareness is the deciding factor. For exercise first, though, I’d choose the M75.
FAQ
The available product information does not state its playtime, so there is no supported battery-life comparison. The M75 lists up to eight hours per charge and up to 80 hours total with its case.
The INSONIXN is specifically described as suitable for small ears and glasses wearers, with an ear-cuff fit around the outer ear. The M75 is described as open-ear and sports-oriented, but its details do not make the same specific fit claims.
The INSONIXN lists a one-hour charge time, compared with 1.5 hours for the M75. Neither listing explains how much listening time a brief charge provides, so a shorter full charge time does not establish faster top-up performance.
