These two look like they belong in the same shopping cart, but they solve completely different problems. One is a personal audio device that happens to survive water. The other is a communication system that happens to play sound. Once you see that split, the decision gets easy.
• Clooissr 32GB — biggest strength: IPX8 waterproofing plus 32GB of built-in memory, so it keeps playing music with no phone and no signal, even fully submerged.
• Clooissr 32GB — biggest trade-off: It's a solo device. There's no intercom, no group chat, no rider-to-rider range — just you and your playlist.
• J-TREK BH03 — biggest strength: Up to 8 riders on one intercom with a claimed 1000m range, DSP and CVC noise reduction, and 14 hours of talk time.
• J-TREK BH03 — biggest trade-off: It's built to clip onto a helmet and talk, not to survive a pool. There's no waterproof rating and no built-in music storage.
• Who Clooissr 32GB is for: The lone rider who wants open-ear music on the bike and the same pair in the pool afterward.
• Who J-TREK BH03 is for: The group rider, the club cyclist, the ski or climb partner who needs to stay in voice contact.
The Clooissr 32GB (model B35) is an open-ear bone conduction headphone with a 32GB memory chip inside it. That combination is the whole point. You load your own music files onto it — the brand's own instructions suggest converting your audio to MP3, WMA, APE or FLAC first — and then you have a self-contained player that doesn't need a phone, a signal, or a pocket. On a bike that matters more than people expect: no cable snagging, no phone mount, no battery anxiety on your handset.
The second thing it does is survive water. It carries IPX8, the highest water-resistance rating, and the brand states it can be submerged to roughly 2 metres. That's why it ships with swim earplugs and two stabilizing straps. The logic is simple — Bluetooth can't travel through water, so underwater you switch to MP3 mode, and above water both modes work normally. For a cyclist who also swims, that's one device instead of two.
The fit is the other design story. Instead of the usual over-ear hooks and two-point clamp, this uses a front cabin plus ear hook, spreading pressure across the ear bone and auricle rather than squeezing your cheekbones. The brand also claims its low-frequency conduction tech cuts vibration by around 80%. Anyone who has worn bone conduction headphones for two hours and felt that dull ache will understand why that claim is the interesting one. At about 25g with a titanium memory alloy band rated to 12,000 bends, it's clearly aimed at long, sweaty sessions.
Who should skip it: anyone whose main goal is talking to other riders. There's no intercom here. Also skip it if you want active noise cancelling — this uses passive noise isolation plus the included earplugs, and the whole design philosophy is the opposite of blocking the world out.
J-TREK BH03: Who It's For
The J-TREK BH03 is not really a headphone in the way most people use the word. It's a helmet-mounted intercom that also plays audio. It comes as a dual pack, it clips onto most bicycle helmets, ski helmets and climbing gear in seconds, and its headline feature is an 8-way group intercom with a range the brand puts at 1000m — about 0.62 miles.
If you ride in a group, that number is the entire product. Eight riders, one channel, no shouting, no stopping at every junction to regroup. On trails or long highway pulls, that's a different sport. The audio side is tuned for exactly that environment too: DSP and CVC noise reduction actively filter wind and road noise, and the brand claims HD-quality voice clarity at speeds up to 70 km/h. Anyone who has tried to take a call at 40 km/h with a normal headset knows how much work those two processing blocks are doing.
Battery is 14 hours of continuous intercom on a charge, with a 60-minute fast charge. Fourteen hours is a big ride plus a long lunch plus the ride home. The fast charge matters if you forgot to plug it in the night before, which is the most common failure mode in cycling electronics.
Bluetooth 5.4 handles pairing to a smartphone, a GPS cycling computer or a speedometer, so hands-free calls and turn-by-turn navigation audio both come through the same unit. Noise control is listed as both active and passive, which is worth noting — this is a device that deliberately reduces what you hear around you, the opposite of the open-ear safety logic.
Who should skip it: the solo rider. If you ride alone, an 8-way intercom is a feature you'll never use, and you'd be paying for radios instead of music. And if you swim, this isn't the one — there's no waterproof rating in the spec sheet at all.
• Best for group rides and rider-to-rider comms → J-TREK BH03. Up to 8 riders, 1000m claimed range, nothing else here comes close.
• Best for riding with music and no phone → Clooissr 32GB. 32GB of onboard storage means your phone stays in your pocket.
• Best for staying aware of traffic → Clooissr 32GB. Open-ear bone conduction lets ambient sound in; the BH03 actively cancels noise instead.
• Best for long days out → J-TREK BH03. 14 hours of intercom versus 8–10 hours of playback on the Clooissr.
• Best for a quick top-up charge → J-TREK BH03. 60 minutes to full, versus 2 hours for the Clooissr.
• Best for swimming and multi-sport use → Clooissr 32GB. IPX8, 2m submersion, swim earplugs and stabilizing straps included.
• Best for helmet-mounted, hands-free nav and calls → J-TREK BH03. Bluetooth 5.4 to a GPS computer or speedometer, dual pack so a riding partner is covered too.
• Best for wind and road noise on the voice side → J-TREK BH03. DSP and CVC are doing the heavy lifting there.
If I ride alone and want music on the bike — and I might swim later — I'd buy the Clooissr 32GB. The 32GB of storage, the IPX8 rating and the open-ear design fit how most people actually ride: solo, with music, wanting to hear the road.
If I ride in a group, I'd buy the J-TREK BH03 without hesitating. Talking to seven other riders at 1000m is a capability the Clooissr simply doesn't have, and 14 hours of intercom covers any ride I'm realistically doing.
In my opinion the mistake is buying either one for the wrong job. Decide whether your ride is a conversation or a soundtrack, and the choice makes itself.
can you bike with headphones
Yes, and open-ear designs are the easiest to live with on a bike because they don't seal your ears. The Clooissr 32GB uses exactly that approach, letting ambient sound in so you can still hear traffic and other riders. Whatever you use, keep the volume low enough to hear what's around you.
what are the best cycling headphones
There's no single answer, because "best" depends on whether you ride solo or in a group. For solo music and swimming, the Clooissr 32GB's 32GB storage, IPX8 rating and open-ear fit make it a strong pick. For group riding, the J-TREK BH03's 8-way intercom and 1000m range make it the more useful tool.
can cyclists wear headphones
They can, and plenty do — the question is which type. Bone conduction and open-ear models like the Clooissr 32GB leave your ear canals open, which is why they're popular with cyclists who want music without losing awareness. Helmet-mounted units like the J-TREK BH03 are built specifically to clip onto cycling helmets.
how to bike with headphones
Keep one ear open to the road, mount or clip the unit securely so it can't shift, and set the volume so you can still hear vehicles. The Clooissr 32GB relies on its ear hook and front cabin for a stable, low-pressure fit, while the J-TREK BH03 clips directly to the helmet shell. Check your local rules before you ride.
