How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the lightest possible open-ear option for long days on the water, choose ASHATA Sport Headphone; if you need bone conduction sound, sweat and rain protection, and all-day battery for fishing, choose Syohoxi Ultra-Comfortable Open-Ear sport. That's the short version. The long version comes down to one word: weight. For fishing — where you're casting, reeling, walking banks and standing in the sun for hours — a headphone you forget you're wearing usually beats one with more features. Here's how the two actually compare.
• ASHATA Sport Headphone — biggest strength: At just 13 g (0.46 oz), it's the lighter of the two by a wide margin, and the open-ear air conduction design keeps your ear canals completely free.
• ASHATA Sport Headphone — biggest trade-off: No microphone, no waterproof rating stated, and no battery-life figure given, so it's a music-first, fair-weather pick.
• Syohoxi Ultra-Comfortable Open-Ear sport — biggest strength: Bone conduction drivers, IP56 sweat/rain resistance, and up to 8 hours of playback with a 5-minute quick-charge top-up.
• Syohoxi Ultra-Comfortable Open-Ear sport — biggest trade-off: At 28 g it's more than twice the weight of the ASHATA, and bone conduction sound isn't for everyone.
• Who each is for: ASHATA for anyone who prioritizes featherweight comfort above all; Syohoxi for anyone who wants durability, battery headroom and call capability in one pair.
The ASHATA Sport Headphone is built around a single idea: get the weight down and keep it there. The frame is premium ABS with skin-friendly silicone, and the whole thing comes in at 13 g — about the weight of a couple of sheets of paper. In my opinion, that's the number that matters most here. When you're standing on a bank working a lure for three hours, a headphone that light simply doesn't register on your head. The open-ear, air-conduction design means nothing goes into your ear canal at all, so you keep full awareness of what's happening around you — footsteps on gravel, a car on the access road, someone calling from the next swim.
Who should buy it? The angler who wants the lightest thing possible, wears glasses, listens to music or podcasts rather than taking calls, and doesn't plan to get it soaked. Who should skip it? Anyone who needs a microphone, anyone who fishes in heavy rain or spray, and anyone who wants a stated battery figure before buying. The sheet doesn't give one, so if runtime is your deciding factor, look at the Syohoxi instead.
Syohoxi Ultra-Comfortable Open-Ear sport: Who It's For
The Syohoxi takes the opposite approach: it's the fully loaded version. This is a bone conduction headphone, which means the drivers send sound through your cheekbones rather than into your ear canal. The open-ear design keeps your ears free for traffic and surroundings, and Syohoxi frames that as a safety feature — sensible if you're cycling to your spot or running the trail before a session. The audio spec is a bone conduction driver with an 80-ohm impedance and a 20 Hz–20,000 Hz frequency range.
The practical wins for fishing are durability and battery. IP56 means it's sealed against sweat and rain, so a surprise shower or spray off the water won't kill it — though Syohoxi is clear that it's not for swimming. Battery life is stated at up to 8 hours of music from a 2-hour charge, plus a genuinely useful trick: a 5-minute charge gives you about half an hour of playback. That's the kind of thing that saves a trip when you realize you forgot to charge the night before.
There's also a microphone with call noise cancellation, so you can take a call mid-session without pulling a phone out of a pocket. The fit uses ultra-lightweight open-ear hooks with a medical-grade silicone coating, and Syohoxi says the design was tested through 5,000+ head movements to stay locked in place. Bluetooth 5.3 with a 10 m range, and one year of warranty, round it out.
Who should buy it? The angler who wants one pair that handles music, calls, sweat and rain, and who values battery headroom over shaving grams. Who should skip it? Anyone who finds bone conduction audio fatiguing, anyone who needs it for swimming, and anyone chasing the absolute minimum weight — at 28 g it's twice the ASHATA.
• Best for ultra-light comfort → ASHATA Sport Headphone. 13 g versus 28 g is not a small gap; it's the entire personality of each product.
• Best for battery life → Syohoxi Ultra-Comfortable Open-Ear sport. Up to 8 hours, with a 5-minute quick charge for 30 minutes of playback.
• Best for wet conditions → Syohoxi Ultra-Comfortable Open-Ear sport. IP56 sweat and rain resistance versus no stated water rating on the ASHATA.
• Best for taking calls → Syohoxi Ultra-Comfortable Open-Ear sport. It has a mic with call noise cancellation; the ASHATA explicitly ships without one.
• Best for glasses and helmet wearers → ASHATA Sport Headphone. Compatibility with glasses and helmets is stated directly in its specs.
• Best for newer wireless tech → Syohoxi Ultra-Comfortable Open-Ear sport. Bluetooth 5.3 versus 5.2, plus a one-year warranty.
• Best for pure music listening with maximum awareness → ASHATA Sport Headphone. Air conduction keeps the ear canal open and the weight near zero.
• Best all-rounder for a full fishing season → Syohoxi Ultra-Comfortable Open-Ear sport. It covers more conditions and more use cases out of the box.
If I were buying one pair for fishing, I'd take the Syohoxi Ultra-Comfortable Open-Ear sport. The reasoning is simple: IP56 sealing and up to 8 hours of battery matter more to me on the water than two extra grams of featherweight comfort, and the quick-charge trick alone would save me from my own bad charging habits. That said, if you've tried open-ear headphones before and the thing that always bothered you was weight and pressure, the ASHATA Sport Headphone is the one I'd point you to — 13 g is genuinely in a different class, and for glasses wearers it's the safer bet. Either way, check the current price on Amazon before you commit, since both are budget-friendly designs that shift around.
For most anglers, the Syohoxi is the better fit — IP56 sweat and rain protection plus up to 8 hours of battery suit long, unpredictable sessions. The ASHATA wins if weight is your top priority and you only fish in dry conditions.
Yes, and that's the main reason to consider this category. Both designs leave your ear canals open so you can hear traffic, other people and your surroundings — a real safety advantage when you're near water or walking banks.
Not universally. Bone conduction (Syohoxi) tends to offer more sealing and feature depth; air conduction (ASHATA) keeps the ear canal fully open and lets you go much lighter. It's a trade-off, not a clear winner.
Only if you take calls mid-session. The ASHATA ships without a microphone, so if calls matter, the Syohoxi is the one to pick.
