How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a comfortable, everyday pair you can wear while running errands, working out or winding down, choose BULYPAZY 2-Pack; if you need headphones that survive full underwater swimming sessions, choose GREYOLK Swimming Headphones. Two very different products, two very different jobs — and the "bluetooth headphones for running" question is exactly where they split.
• BULYPAZY 2-Pack — biggest strength: two headbands in one pack, with ultra-thin HD speakers built into a twist-knotted fabric band, so you get audio and a wearable accessory in a single item.
• BULYPAZY 2-Pack — biggest trade-off: it's a fabric headband, not a waterproof device. There's no IP rating in the specs, so treating it as a swim product would be a mistake.
• GREYOLK Swimming Headphones — biggest strength: IP68 waterproofing plus 32GB of built-in MP3 storage, so you can leave your phone behind and listen underwater.
• GREYOLK Swimming Headphones — biggest trade-off: Bluetooth doesn't work underwater at all — you must double-click into MP3 mode — and the open-ear bone conduction design trades isolation for safety.
• Who each is for: BULYPAZY for women who want a discreet, stylish headband for running, yoga, travel and casual wear; GREYOLK for swimmers and open-water athletes who need audio that keeps working when it's soaked.
The BULYPAZY 2-Pack is a headband first and a headphone second. The band is polyester in a one-size twist-knotted design, and the speakers sit inside it as ultra-thin drivers that play music, handle audiobooks and take phone calls. Because the speakers are adjustable and you position them over your ears yourself, the fit is more about how you wear the band than about ear tips or hooks. That's the appeal: nothing goes inside your ear canal, so there's no pressure, no buds falling out mid-stride, and nothing to fiddle with when you're moving.
For running and gym work, that matters more than people expect. A headband stays put, doesn't bounce, and doesn't need readjusting every few minutes. The stated specs back this up reasonably well — Bluetooth pairing with automatic reconnect to your last device, a 45-foot wireless range, and 1–2 hours of charging for more than 12 hours of playback. Twelve hours is a long time; for most people that's a week of workouts on a single charge, and the 45-foot range means you can leave your phone on a bench or treadmill tray and still stay connected. The set also includes two headbands, a Type-C cable and a quick guide, with a one-year warranty described.
The honest trade-offs: this is not a waterproof product, and nothing in the specs claims an IP rating, so sweat is one thing but swimming is out. There's also no active noise cancellation here, and no bone conduction — the sound is coming from small speakers sitting against your head through fabric, so don't expect the isolation of in-ear buds in a loud gym.
GREYOLK Swimming Headphones: Who It's For
The GREYOLK Swimming Headphones are built around one hard problem: playing audio underwater. The answer is two-part. First, IP68 waterproofing — described as completely waterproof, sweatproof, rainproof and dustproof, usable with a swim cap, goggles and earplugs. Second, 32GB of built-in memory holding up to 6,000 songs across MP3, WMA, WAV, APE and FLAC. That combination is the whole point: Bluetooth does not transmit through water, so you switch to MP3 mode with a double-click of the power button and the headphones play from their own storage with no phone involved.
The rest of the spec sheet reads like a serious training tool. Bone conduction drivers, 15mm, with a frequency range of 20Hz–20,000Hz and 8-ohm impedance, sit outside your ear canal so you stay aware of traffic, other swimmers and whatever's happening around you. The frame is a wraparound titanium design meant to hold steady through intense training, and the whole unit weighs about 32–34 grams. Bluetooth 5.4 (with the style field listing 5.3) gives a 10-metre range with stronger interference resistance and more stable connections. Battery is 150mAh: 1.5 hours of charging for up to 8 hours of playback or talk time. Active noise cancellation is listed among the controls. GREYOLK also describes a two-year after-sales service.
The trade-offs are real and worth naming. Eight hours is solid but well short of the BULYPAZY's stated 12-plus, and the 10-metre Bluetooth range is a fifth of the BULYPAZY's 45 feet — fine for a pool deck, less generous around a house. Bone conduction sound is thinner than in-ear audio, and open-ear means you hear the world, not just your music. There's also a learning curve: remembering to switch modes before you get in the water is a genuine habit to build.
Who should buy it: swimmers, snorkelers, and anyone doing water sports or sweaty outdoor training who wants audio without blocking their ears. It's also a strong pick for runners who refuse to carry a phone, since the internal memory plays without one. Who should skip it: casual listeners who mostly want music at a desk or on a commute, and anyone who wants deep bass or total noise isolation.
Side-by-Side: Which Should You Choose?
• Best for running in the city or on a track → both work, but differently. BULYPAZY gives you 12+ hours and a 45-foot range; GREYOLK gives you open-ear awareness and phone-free playback from 32GB of storage.
• Best for battery life → BULYPAZY 2-Pack. More than 12 hours of playback versus 8 hours on the GREYOLK.
• Best for charging speed → tie. Both state 1–2 hours (BULYPAZY) and 1.5 hours (GREYOLK) to full charge.
• Best for wireless freedom → BULYPAZY 2-Pack. A 45-foot range beats the GREYOLK's 10 metres.
• Best for leaving your phone at home → GREYOLK Swimming Headphones. 32GB of internal storage holds up to 6,000 songs.
• Best for style and everyday wear → BULYPAZY 2-Pack. A polyester twist-knotted headband you'd wear with normal clothes, in a two-pack.
• Best for situational awareness → GREYOLK Swimming Headphones. Open-ear bone conduction keeps you tuned in to your surroundings.
If I had to pick one, I'd buy the GREYOLK Swimming Headphones — but only if water is genuinely part of your routine. IP68 waterproofing plus 32GB of internal memory solves something no ordinary headband can, and the open-ear design makes it a genuinely safe choice for running outdoors too. If you don't swim, that capability is wasted on you. In that case I'd take the BULYPAZY 2-Pack: two wearable headbands, 12+ hours of playback and a 45-foot range make it the better everyday running and casual companion. Check the current price on Amazon before you commit, since both sit in different budget brackets.
what are the best bluetooth headphones for running
For running specifically, look at what the specs solve. The BULYPAZY 2-Pack gives you 12+ hours of playback, a 45-foot Bluetooth range and a fabric headband that stays put without ear tips. The GREYOLK adds IP68 waterproofing, open-ear awareness and 32GB of phone-free storage — better if you sweat heavily or run near water.

Can I use the GREYOLK Swimming Headphones for running?
Yes. The open-ear bone conduction design is explicitly pitched for running, cycling and exercising, and it keeps you aware of traffic and surroundings. It weighs about 32 grams with a wraparound titanium frame, so it stays stable during training. Just remember Bluetooth works on land only — underwater you need MP3 mode.
No. The specs list polyester band material, a one-size fit and a 1–2 hour charge for 12+ hours of playback, but no waterproof rating. Sweat and light rain are one thing; submerging them is not something the product information supports. For swimming, the GREYOLK's IP68 rating is the one to look at.
