If you want a featherweight clip-on design that disappears on your ear and stays put through sweaty workouts, choose Piluyaa Clip-on Earbuds; if you need longer per-charge listening time and a secure ear-hook fit with situational awareness, choose Monster AC317.
• Piluyaa Clip-on Earbuds — biggest strength: at just 5.3g per earbud with a C-shaped clip and slim hook, it's one of the lightest open-ear options here, and it's built with glasses wearers in mind. It also carries IPX5 water resistance.
• Piluyaa Clip-on Earbuds — biggest trade-off: 6 hours per charge and 24 hours total with the case is solid for daily use but not the longest single-charge runtime in this comparison, and the clip-on style may feel less anchored than a hook for some people.
• Monster AC317 — biggest strength: 7 hours per charge and up to 24 hours with the case, plus a flexible ear hook and balanced weight for a soft, secure grip. Type-C fast charge fills the case in about an hour.
• Monster AC317 — biggest trade-off: the hook design is bulkier than a slim clip, and its sound tuning focuses on mid to high frequencies rather than a full-range profile.
• Who Piluyaa is for: glasses wearers, gym-goers, and anyone who wants the lightest possible open-ear clip and doesn't mind a shorter single-charge window.
• Who Monster is for: commuters, runners, and long-session listeners who want extended playtime, a hook-style secure fit, and quick Type-C charging.
The Piluyaa Clip-on Earbuds are an open-ear design built around a C-shaped ear clip and a slim hook. Instead of pushing into your ear canal, they sit outside it, which is the whole point of open-ear audio: you keep your music going while still hearing traffic, coworkers, or a running partner. At 5.3 grams per earbud, the weight is the headline here. That's light enough that the clip basically vanishes during a long shift or a slow run. If you wear glasses, the clip-on approach is a genuine advantage, because there's no hook fighting for space behind your ear.
The spec sheet reads like a daily-driver set. Bluetooth 5.4 handles the connection with low latency, dual sonic directional transmission keeps sound from leaking out to the people around you, and ENC noise cancellation cleans up your voice on calls. Battery life is 6 hours on a single charge, with the case adding enough for 24 hours total. IPX5 means splashes, rain, and sweat are fine. Touch controls round it out, so you're tapping rather than digging for your phone.
In my opinion, you should buy the Piluyaa if you wear glasses, train hard, and want the lightest clip-on fit you can get without a hook digging in. Skip it if your priority is squeezing the most hours out of a single charge, or if you prefer the feel of an ear hook over a clip.
The Monster AC317 takes the hook route. It's an open-ear design with a flexible ear hook and a balanced earbud weight, which is the classic setup for people who want their earbuds to feel locked in. The enclosure is plastic with an ultra-soft silicone cushion, and the whole thing is sweat resistant and rated IPX6, which is a step up from splash protection if you're logging serious miles in the rain.
Where Monster leans hard is battery and calls. You get 7 hours per charge and up to 24 hours with the case, and the case refills in about an hour over Type-C. That fast top-up matters more than it sounds: it means a short coffee break can get you back out the door. Monster's audio tuning uses a digital processor and dynamic drivers to lift the mid to high frequencies, so vocals and podcasts come through clearly while your ears stay open. AI noise reduction handles call clarity, and touch controls cover music, volume, calls, and your voice assistant. Bluetooth range is listed at 10 meters.
I'd point you to the AC317 if you want a hook that stays planted, longer per-charge listening, and quick charging. Skip it if you specifically want the smallest, lightest clip-on possible, or if you wear glasses and worry about the hook crowding your frames.
• Best for glasses wearers → Piluyaa Clip-on Earbuds, thanks to the C-shaped clip and slim hook that avoid the behind-the-ear space your frames use.
• Best for battery per charge → Monster AC317, at 7 hours versus Piluyaa's 6.
• Best for total battery with the case → a tie on paper, since both land at 24 hours.
• Best for fastest charging → Monster AC317, with a case that fills in roughly 1 hour via Type-C (Piluyaa lists 6 hours charge time).
• Best for the lightest fit → Piluyaa Clip-on Earbuds at just 5.3g per earbud.
• Best for water and sweat resistance → Monster AC317 with IPX6 versus Piluyaa's IPX5.
• Best for call clarity features → both are strong, with ENC on Piluyaa and AI noise reduction on Monster.
• Best for a locked-in hook fit → Monster AC317, with its flexible ear hook and balanced weight design.
If I were buying for myself, I'd take the Monster AC317. The extra hour per charge, the one-hour Type-C case refill, and the IPX6 rating fit the way I actually use open-ear buds — long walks, rainy runs, and podcast binges where I don't want to think about the battery. The hook fit also gives me more confidence mid-stride. That said, if you wear glasses or you're chasing the absolute lightest clip-on feel, the Piluyaa Clip-on Earbuds are the smarter pick, and 24 total hours still covers a full day. Worth checking the current price on Amazon before you commit, since both sit in a similar open-ear bracket.
Neither model goes into your ear canal. The Piluyaa clips onto the outer ear with its C-shaped bridge and slim hook, while the Monster AC317 loops its flexible ear hook over the top of your ear and rests the earbud outside the canal.
Both sets use touch controls rather than physical buttons. On the Piluyaa you tap the earbud housing; on the Monster AC317 you touch to switch music, adjust volume, take calls, or trigger your voice assistant. Both connect wirelessly over Bluetooth 5.4.
"Opening" here just means taking the earbuds out of the charging case, which powers them on. Both the Piluyaa and the Monster AC317 pair over Bluetooth 5.4, so you enable Bluetooth on your phone, pick the earbuds from the list, and you're set.
Use the touch panels. The Piluyaa relies on ENC to reduce background noise on calls, while the Monster AC317 uses AI noise reduction. Music playback, volume, and call handling are all handled by taps on both models.
