• PureGear PureBoom — biggest strength: A rounded, in-ear fit with a wireless charging case that holds up to three full charges, plus a lifetime warranty and 30-day money-back guarantee.
• PureGear PureBoom — biggest trade-off: In-ear sealing means you're isolated from your surroundings, and the 18-hour figure is the bud's average life rather than an open-ear, all-day sport design.
• Monster Open Ear AC510 — biggest strength: Open-ear placement with a liquid silicone, pressure-sensing fit, IPX5 water resistance and Bluetooth 6.0.
• Monster Open Ear AC510 — biggest trade-off: Open-ear buds leak sound in and out by design, so you won't get the sealed isolation of an in-ear model.
• Pick PureGear PureBoom if you want sealed sound, hands-free calling and a case you can drop in a pocket.
• Pick Monster Open Ear AC510 if you want awareness, sweat resistance and a fit that survives movement.
The PureBoom is an in-ear bud with rounded silicone tips, a plastic-and-silicone build, and a single color option: pink. It pairs over Bluetooth 5 with a stated range of up to 32 feet, which is generous enough to walk away from your laptop mid-call without dropping the connection. PureGear lists compatibility across iPhone, Galaxy and most other Bluetooth devices — phones, tablets, laptops, PCs, smart TVs, gaming consoles and smartwatches — so this is a bud meant to move between devices rather than live with one.
The audio side is a dynamic driver covering 20 Hz to 20,000 Hz, which is the standard full-range span you'd expect at this tier. What matters more day to day is the control scheme: touch control handles media, volume and answering calls, so you're not hunting for your phone. There's a built-in mic for hands-free calling, and the whole package is described as compact, lightweight and travel-friendly. The charging case is wireless, and PureGear says it provides up to three full charges while staying small enough for a pocket. Battery is listed at 18 hours average life for the buds and 18 hours for the carrying case, with a 1.5-hour charge time.
Monster Open Ear AC510: Who It's For
The AC510 takes the opposite approach. These are open-ear buds, meaning they sit outside the ear canal instead of sealing it. Monster builds them from liquid skin-friendly silicone and adds ear pressure sensing that adjusts the fit as you move, which is the mechanism behind the "360° biomimetic fit" claim — the point is stability and preventing dropout during activity. If you've had buds work loose on a run, that design choice is the whole reason to look here.
Sound comes from a 13 mm broadband PU titanium diaphragm dynamic driver, which Monster frames around a wide, energetic sound field. Noise handling is adaptive: the AC510 combines active noise reduction with voice recognition and adaptive filtering for what Monster calls AI intelligent noise reduction, aimed primarily at cleaning up calls. Connectivity runs on Bluetooth 6.0, which Monster describes as faster and lower-latency than older versions — useful for video where audio-video sync matters.
Touch control is central again: tap to answer calls, skip tracks or adjust volume without touching your phone. The charging case uses a sliding cover rather than a flip lid, and it includes a liquid silicone lanyard, which is a small but genuinely nice touch if you clip things to a bag. Battery is listed at 25 hours average life including the case. Water resistance is IPX5, so sweat and light rain are covered — note that Monster's marketing copy also mentions IPX6 in one place, but the spec field says IPX5, so I'd treat IPX5 as the working figure. The color is white, and Monster lists the age range as all ages.
This is the one for runners, gym-goers and commuters who want to stay aware of their environment. Skip it if you want maximum isolation on a plane or in a loud office, because open-ear design fundamentally can't deliver that.
• Best for battery life → Monster Open Ear AC510: 25 hours total with the case versus 18 hours for the PureBoom.
• Best for sealed, isolating sound → PureGear PureBoom: in-ear silicone tips block more of the room around you.
• Best for workouts, sweat and light rain → Monster Open Ear AC510: IPX5 water resistance and a pressure-sensing, movement-stable fit.
• Best for hands-free calling range → PureGear PureBoom: up to 32 feet of Bluetooth range with a built-in mic.
• Best for newest Bluetooth standard → Monster Open Ear AC510: Bluetooth 6.0 versus Bluetooth 5.

• Best for staying aware of traffic → Monster Open Ear AC510: open-ear placement never blocks your surroundings.
If I had to buy one, I'd take the Monster Open Ear AC510, because the combination of an open-ear fit, IPX5 protection and 25 hours of total playback covers the way I actually use earbuds — moving around, outdoors, one ear on the world. But that's a preference for awareness and activity, not a claim that it's better across the board. If your listening is mostly seated — calls, streaming, desk work — and you'd rather have sealed sound plus a lifetime warranty behind the purchase, the PureGear PureBoom is the smarter buy. Check the current price on Amazon before you commit, since that's the one variable that can flip this decision either way.
Touch control means the earbud's outer surface responds to taps and swipes instead of physical buttons. Both the PureBoom and the AC510 use it to handle media playback, volume and answering calls. PureGear describes it as convenient control for music, volume and calls; Monster highlights improved sensitivity for faster feedback.
How to disable touch controls on headphones
There's no disable function listed in either data sheet, so neither the PureGear PureBoom nor the Monster Open Ear AC510 documents a way to switch touch control off. If accidental taps bother you, the practical workaround is to adjust how you grip the bud when inserting or removing it, or to manage playback from your phone instead. Any deeper setting would depend on your phone's own app, not the earbuds.
Because touch control sends commands over the Bluetooth connection — a tap is read as play, pause, track skip or call answer, exactly as both of these models are designed to do. The PureBoom's control type is listed as media control over touch, and the AC510's touch design lets you answer calls, change tracks and adjust volume without the phone. It's normal behavior, not a fault.
Only the Monster Open Ear AC510 lists water resistance, at IPX5, along with a liquid silicone, pressure-sensing open-ear fit. The PureGear PureBoom lists no water rating; its fit is sealed in-ear with rounded silicone tips. So for sweat and rain, the AC510 is the one with a stated rating, while the PureBoom prioritizes isolation and comfort.
