Monster AC317 Open Ear Review: Open-Ear Hook Headphones Tested
The Monster AC317 are ear-hook headphones that sit outside your ear canal — music plays, but the world stays audible. For runs, bike commutes, or working at home with a toddler on your hip, the concept delivers. You're not paying for deep bass or noise cancellation, and you don't get them. Honest deal at around $60.
There's a category of purchases you only make after getting burned once by regular earbuds — you went for a run, didn't hear the cyclist coming up behind you, and decided nothing's going back in your ears ever again. That's exactly who open-ear headphones are for. Monster, a brand that used to mean exclusively pricey "prestige" cables, now makes budget electronics for the masses, and the AC317 is precisely that kind of product: not about status, just about working without annoyance.
What This Format Actually Is
Open-ear headphones aren't exactly new — Shokz (formerly AfterShokz) has owned this niche for years with bone conduction. The AC317 works differently: sound comes from a miniature driver suspended near the entrance to your ear canal, not touching it. Cheaper to manufacture, which is why these cost a fraction of the Shokz OpenRun. Upside and downside rolled into one: cleaner, louder sound than bone conduction, but you lose detail in wind or on the subway.
They wear like a hook over the ear — light, flexible, and they stay put even when you shake your head. First five minutes feel weird, like something's clipped onto you from the outside, then you forget. That's the format's killer feature: an hour into a run, your ears don't ache or itch the way they do with silicone tips when summer heat and sweat do their thing.
How It Plays Out in Real Life
Bluetooth 5.4 isn't just a checkbox here — the connection holds steady even with your phone in a back pocket, not in your hand. The claimed 24 hours is total with the case, naturally, but it's closer to reality than half the competitors at this price: two to three workdays without charging is totally doable if you don't keep volume maxed constantly.
Sound — let's be straight: there's no bass to speak of. Physics of the format won't let you seal the ear, so low frequencies just leak into the air instead of hitting your eardrum. For podcasts, audiobooks, calls, and background music — more than enough. For a gym playlist built on heavy bass — you'll be disappointed, and honestly that goes for all open-ear headphones, not just Monster.
Where the AC317 genuinely wins: situations where sealed ears are unsafe or just impractical. Running alongside traffic, cycling through the city, cooking while needing to hear the timer and the kid, taking a work call in an open office when a colleague shouts your name. Compared to classic TWS like AirPods or no-name budget buds — it's a completely different philosophy, not "immersion in sound" but "music as a backdrop to reality."
The microphone is standard for this price tier: voice comes through clearly in a quiet room; outdoors with wind it degrades — the other person might ask you to repeat. For everyday "Hey, I'm heading out now" calls — perfectly fine. For important negotiations, you're better off with a proper headset or ANC mic headphones.
Who Should Buy, Who Should Pass
Get them if: you run or cycle in the city and need to hear traffic; you're on calls at home with kids or pets around; you wear glasses and TWS rubbing against the temples all day drives you nuts (similar issue remains here, but the hook sits differently and usually more comfortably). At roughly $60, the purchase isn't scary even if the format turns out "not yours" — this isn't the segment where a mistake hurts.
Skip them if: you listen to music at home in silence and want to hear every bass nuance; you fly often and dream of noise cancellation; or you live somewhere seriously windy and plan to run along the coast — wind in the mic and the driver will be a noticeable enemy. Honestly, for pure critical listening there are far better options even in this same budget.
The core trade-off is simple: you trade sound quality and bass for safety and awareness of what's happening around you. The second, less obvious trade-off — fit. The ear hook doesn't suit every head shape equally; some people feel pressure after an hour. If you can try before you buy, do it.
Monster AC317 sell on marketplaces for around $60 — not the cheapest in the headphones category, but not a premium price for a format that objectively loses on bass to closed models.
FAQ
The hook grips behind the ear, not inside it, so the chance of anything flying off on bumpy terrain is way lower than with in-ear tips. Tested on asphalt and gravel — they stayed locked in even with sharp head turns.
Shokz cost more and use bone conduction — sound feels different, more "humming in your temples," takes getting used to. AC317 sounds more natural to the ear because it's a regular mini-driver, at half to a third the price. If budget's tight and you want to try the format for the first time — start with Monster, don't overpay for a flagship right away.
No, and that's honestly the weakest point of any open-ear headphones, not just this model. If bass in the track is half your gym motivation, look at closed TWS with active noise cancellation instead.
Yes, for everyday short calls the mic is plenty clear. Outdoors in strong wind quality drops — better to hold the phone closer to your mouth or step somewhere quiet.
