• MEE audio M6 — biggest strength: adjustable memory wire earhooks plus six sets of eartips give a locked-in over-ear fit that simply doesn't fall out, with IPX5 sweat and water resistance behind it.
• MEE audio M6 — biggest trade-off: it's a sport bud first, so the shell, cable and shirt clip are built for movement, not for lying with your head on your arm at a library table.
• Hearprotek 2 — biggest strength: 10.5 g per pair of soft silicone with a double-layer ergonomic shape designed to sit without digging into the ear canal, which is exactly what side sleepers and long sitters need.
• Hearprotek 2 — biggest trade-off: no water-resistance rating and a light, sleep-first build, so it's the wrong tool for heavy sweating or rough handling.
• For the library and sleep: Hearprotek 2.
• For the gym, running and commuting: MEE audio M6.
The M6 is a USB-C wired in-ear headphone with a clear polyurethane and TPE shell, 16 ohm impedance, dynamic drivers covering 20Hz to 20,000Hz, and an in-line mic with a 3-button remote for calls, playback and volume. The headline feature is the memory wire: a section of cable that holds whatever shape you bend it into, so it wraps behind your ear and stays put. Add six pairs of eartips and a shirt clip and you have a fit system, not just a pair of buds. That's a real advantage if your ears have never gotten along with one-size eartips.
Who should buy it? Anyone whose listening happens while moving. Running, lifting, cycling, walking to class with a backpack on. The IPX5 rating means sweat and light rain aren't a concern, and the shirt clip keeps the cable from snagging on a hoodie or bag strap. The 3-button remote is genuinely useful when your phone is zipped away. It's also a clean pick for anyone who has already moved to USB-C and doesn't want a dongle: it's compatible with USB-C iPhones, iPads, MacBooks, laptops and Android devices with a Type-C connector.
Who should skip it? If your main use is lying down. Library sessions where you lean your head on your hand, naps at a desk, or actual sleep. The over-ear memory wire and sport-tuned shell are designed to stay locked onto a moving head, and that same structure can press against your ear when your head is resting on something. It also isolates sound but doesn't claim active noise cancellation, so it's not a magic shield against a loud room.
The Hearprotek 2 is built around one idea: make the earbud disappear. Each pair weighs 10.5 g (0.37 oz), the enclosure is soft silicone, and the double-layer ergonomic design is shaped to mold to your ear rather than jam into the canal. That's the difference between an earbud you tolerate for forty minutes and one you forget about for three hours. It comes as two pairs in a carbon finish, which is a practical detail if you keep one set at home and one in a bag.
The audio side is more thoughtful than the price bracket of "sleep bud" usually suggests: a high-resolution DAC chip and a film diaphragm, tuned for clear voices and detail. For audiobooks, podcasts and quiet music while you read, that's the right target. The in-line 3-button remote handles calls and playback, and the 125 cm extra-long thin wire gives you slack to move your head or shift position without yanking a bud loose. The cable is described as tough, bulletproof-style wire, which matters when you're rolling over on it.
Who should buy it? Side sleepers, snorers' partners, students who live in the library, and anyone who wants touch-control-free, cable-free-of-bulk simplicity. If you've ever taken a bud out after an hour because your ear ached, this is the design brief you want. It's also a strong pick for an open-ear-averse listener who just wants something small and soft that blocks a bit of room noise through fit and silicone rather than electronics.
Who should skip it? Anyone who sweats hard or trains outdoors. There's no IPX rating here, and the silicone-plus-thin-wire build is optimized for gentleness, not abuse. If you need a bud that survives rain, a gym bag and a water bottle leak, the M6 is the safer call.
• Best for the library → Hearprotek 2. Soft silicone, 10.5 g, double-layer ergonomic shape, and a long thin cable you can route without tugging.
• Best for sleep and side sleeping → Hearprotek 2. The whole design is aimed at pressure-free rest.
• Best for workouts and running → MEE audio M6. IPX5 plus memory wire earhooks is a combination built for sweat and motion.
• Best fit security while moving → MEE audio M6. Memory wire and six eartip sizes beat a fixed silicone shape for staying in.
• Best for clear spoken-word detail → Hearprotek 2. A high-resolution DAC chip and film diaphragm are tuned for voices and detail.
• Best for extra cable length → Hearprotek 2. 125 cm of thin wire versus the M6's shirt-clip-managed sport cable.
• Best for sweat, rain and rough handling → MEE audio M6. IPX5 is the difference-maker.
• Best for a one-eartip-fits-nobody ear → MEE audio M6. Six sets to choose from.
• Best for a spare set → Hearprotek 2. It ships as two pairs.
If you're picturing a bluetooth clip on earbuds setup for the library, neither of these is wireless — both are wired USB-C — so treat them as the low-hassle wired alternative. The Hearprotek 2 is the one I'd hand to someone who wants touch control open ear earbuds levels of comfort but actually wants sound isolation; the M6 is the one for someone who'd otherwise be shopping on ear headphones for library use and wants something far smaller.
For the library, I'd buy the Hearprotek 2. The reason is narrow and specific: comfort under stillness. Ten and a half grams of soft silicone with a double-layer ergonomic shape is a design that answers the exact problem library listeners have, which is ear fatigue after hour two. The M6 is the better earbud for a run, and I wouldn't argue with anyone who buys it for that. But if your listening is a desk, a chair and a book, the Hearprotek 2's sleep-first build wins, and the two-pair pack means you can leave one in your bag permanently. Check the current price on Amazon before you commit, since both sit in a category where the value math changes fast.
For library use I'd pick the Hearprotek 2. Its soft silicone build, 10.5 g weight and double-layer ergonomic shape are designed for long, still sessions, while the M6's memory wire and sport fit are aimed at movement.
No. Both are wired USB-C headphones. The MEE audio M6 uses a USB-C connector with an in-line mic and 3-button remote, and the Hearprotek 2 uses a Type-C jack with a 3-button in-line remote.
Neither lists active noise cancellation. Both rely on sound isolation through fit: the M6 through its eartip seal, and the Hearprotek 2 through its silicone double-layer design that molds to the ear.
Yes, if the device has a USB-C audio connection. It's listed as compatible with USB-C iPhones, iPads, MacBooks, laptops, computers and other Type-C devices. If your device still uses Lightning or a headphone jack, neither of these is the right connector.
