• GREYOLK's biggest strength: a true IP68 waterproof, dustproof build with bone conduction audio and 32GB of onboard MP3 storage — no phone required.
• GREYOLK's biggest trade-off: open-ear bone conduction means you trade deep, sealed bass for situational awareness, and the 8-hour battery is modest next to the competition.
• Generic Neckband's biggest strength: a 48-hour battery with a real-time LED power display and a high-visibility orange neckband.
• Generic Neckband's biggest trade-off: IPX4 only resists sweat and light splashes — it is not a swimming product, so keep it out of the pool.
• Who each is for: GREYOLK for swimmers, snorkelers and anyone training near water; Generic Neckband for warehouse and construction workers, gym-goers and long-shift users who hate charging.
GREYOLK's whole identity is the water. The IP68 rating is the headline — fully waterproof, dustproof, sweatproof and rainproof — and the spec sheet lists swimming, snorkeling, fishing and boating as intended uses. That is a genuinely unusual claim for a headphone, and it's the reason this product exists. If you want music while you do laps, this is the shortlist.
The second half of the story is the 32GB of built-in memory. GREYOLK stores up to roughly 6,000 songs locally and plays MP3, WMA, WAV, APE and FLAC files directly, which matters enormously underwater because Bluetooth does not travel through water. You double-click the power button to flip between Bluetooth mode and MP3 mode. In Bluetooth mode you get 5.3 wireless with a 10-metre range — fine for running, cycling and the gym, but the MP3 mode is what actually makes pool sessions work.
Physically it's an open-ear bone conduction design weighing 32 grams, with a wraparound titanium frame for stability and a 30mm bone conduction driver. The ABS build and black finish are understated. You get a 150mAh battery rated for 8 hours of playback or talk time after a 1.5-hour charge, button controls, active noise cancellation and a magnetic charging cable that also lets you mount the headset to a computer to manage the internal storage. Warranty documentation in the sheet mentions both a 1-year after-sales service and a 2-year warranty description.
Who should buy it: lap swimmers, open-water swimmers, snorkelers, and runners or cyclists who want their ears open to traffic. Who should skip it: anyone who wants thumping, sealed-in bass, and anyone who needs multi-day battery between charges. Bone conduction is also a poor fit if you need total noise isolation.
Generic Neckband is a workhorse, and it's honest about it. The 48-hour battery life is the anchor feature, paired with a real-time LED digital display so you always know your remaining charge. For long shifts, double shifts, or a week of commuting without thinking about a charger, that combination is genuinely useful — and it's the exact opposite priority from GREYOLK.
The design leans into visibility and safety. It's a bright orange neckband with magnetic in-ear buds that snap together when idle so they don't tangle in a pocket or around your neck. The neckband itself is soft and flexible for all-day wear, and the sheet specifically calls out warehouse, construction and gym use. IPX4 means it handles sweat and light splashes — it will survive a hard workout or a rainy commute, but it will not survive a swim.
Audio is a 13mm dynamic fiber driver with 80-ohm impedance, tuned for balanced treble and bass rather than bone conduction's open presentation. You get three working modes: standard Bluetooth, TF-card MP3 playback, and an ear-return monitoring mode. Bluetooth 5.4 supports pairing two devices at once with quick switching between a phone and a tablet, plus hands-free calling via the built-in mic. There's also a low-latency game mode for audio-video sync, and the fit is described as secure even under vigorous shaking.
Who should buy it: warehouse staff, builders, gym regulars, commuters and gamers who want long runtime, a mic, and in-ear sound. Who should skip it: swimmers, snorkelers, and anyone who needs a genuinely waterproof headphone. The orange color is also a deliberate safety choice, not a neutral one — if you want something discreet, this isn't it.
• Best for swimming and water sports → GREYOLK Swimming Headphones. IP68 versus IPX4 is the whole ballgame here.
• Best for battery life → Generic Neckband. 48 hours versus 8 hours is a six-fold difference, and the LED display removes the guesswork.
• Best for listening without a phone → GREYOLK Swimming Headphones. 32GB of onboard storage holds thousands of tracks; the neckband's TF-card mode requires you to supply your own card.
• Best for situational awareness → GREYOLK Swimming Headphones. The open-ear bone conduction design keeps your ears free, which is safer on roads and trails.
• Best for bass and sealed-in sound → Generic Neckband. A 13mm in-ear dynamic driver will always out-punch an open-ear bone conduction driver for low-end impact.
• Best for calls and dual-device switching → Generic Neckband. Bluetooth 5.4 with simultaneous pairing of two devices and a built-in mic.
• Best for high-visibility workplaces → Generic Neckband. The bright orange neckband is designed to be seen on site and in low light.
• Best for a lightweight, barely-there feel → GREYOLK Swimming Headphones. It weighs 32 grams and uses a wraparound titanium frame instead of a neckband.
In my opinion, most people shopping this comparison should buy the Generic Neckband. It lasts six times longer per charge, it handles calls and two devices at once, it costs less to replace if you lose it, and it covers the gym, commute, gaming and job-site use cases that make up most people's actual week. The only reason to pick the GREYOLK Swimming Headphones instead is if water is non-negotiable for you — and if it is, GREYOLK is the clear choice, because the neckband simply cannot go where you're going. Buy the GREYOLK if you swim. Buy the neckband for everything else.
Yes — it carries an IP68 rating, described as completely waterproof, sweatproof, rainproof and dustproof, and the manufacturer lists swimming, snorkeling, fishing and boating as intended uses. The Generic Neckband is only IPX4, which covers sweat and light splashes, not submersion.
No. It has 32GB of built-in memory holding up to about 6,000 songs and plays MP3, WMA, WAV, APE and FLAC directly. You double-click the power button to switch between Bluetooth and MP3 mode. That matters because Bluetooth doesn't transmit well through water.
The Generic Neckband by a wide margin — it's rated for 48 hours of playtime with a live LED power display. The GREYOLK is rated for 8 hours of playback or talk time after a 1.5-hour charge. If charging frequently annoys you, the neckband wins.
Both work, but for different reasons. The GREYOLK is lighter at 32 grams and keeps your ears open to your surroundings, while the Generic Neckband offers a secure in-ear fit, 48-hour runtime and low-latency game mode. For sweaty indoor workouts, either is fine — just don't swim in the neckband.
