How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a fully loaded open-ear package with a charging case, extended total playtime and on-case battery readouts, choose Fidiso Over Ear Bud; if you need maximum single-charge stamina, the newest Bluetooth generation and the highest water-resistance rating, choose Conyat Open-Ear Headphones.
• Fidiso's biggest strength: a complete kit — charging case, 30–40 hours of total playtime, a dual LED power display, flexible ear hooks and Bluetooth 5.4 with multipoint pairing.
• Fidiso's biggest trade-off: the driver is listed at 8 mm in the spec sheet even though the marketing text talks about a 16 mm unit, and the waterproofing stops at IPX5.
• Conyat's biggest strength: a genuinely modern spec sheet — Bluetooth 6.0, around 6.7 g per earpiece, roughly 10 hours on a single charge and an IP7 waterproof rating.
• Conyat's biggest trade-off: no charging case, no stated total playtime and no listed total battery capacity, so what you get per charge is what you get.
• Pick Fidiso if you want a case that refills your buds, a live battery percentage and a sport-friendly kit for commutes, workouts and travel.
• Pick Conyat if you want the lightest possible fit, the newest Bluetooth version and the toughest water protection for sweaty outdoor sessions.
Fidiso is the "everything in the box" option. The earbuds use flexible ear hooks that bend without losing shape and sit around the outside of the ear rather than inside the canal, so nothing presses on your ear canal during long sessions. Because sound is transmitted directionally — the brand describes a ±25° adjustment window that follows how the buds sit on your head — the design claims to cut leakage by up to 95% while leaving you aware of traffic, coworkers or a kid asking a question from the next room. That combination is why I'd point parents, office workers and runners toward this one.
The battery story is the real differentiator. Fidiso lists 6–8 hours of playback per charge, so call it about 7 hours as an average, and the charging case pushes the total to 30–40 hours. The case itself has a 300 mAh cell and a dual LED display that shows remaining power from 1% to 100%, which is genuinely useful when you're heading out for a long run or a flight and don't want to guess. A 10-minute top-up is listed as good for about 2 hours of playback, and the case recharges over Type-C in roughly 1.5 hours. The package includes the buds, the case, a Type-C cable, a lanyard and a manual.
Where Fidiso gives ground: the spec sheet lists an 8 mm dynamic driver, which sits below the 14.2 mm figure the product text compares itself against, so I'd treat the "big driver" language with caution and judge it on the ear-hook fit and feature set instead. Water resistance is IPX5 — fine for sweat and light rain, not for swimming or heavy downpours. There's also a 60 ms latency figure listed, which is acceptable for streaming but not a competitive-gaming number. If you want the maximum single-charge runtime or the newest Bluetooth version, this isn't the pick.
Conyat takes the opposite approach: strip the kit down and put everything into the earpieces. Each side weighs about 6.7 g, and the design keeps the ear canal completely unobstructed while still contouring the ear for a secure hold. In practice that means the X5S is the pair you forget you're wearing — the kind of thing you keep on for a full workday of calls and background music, or for a long run where anything heavier starts to nag at the top of your ear.
The headline numbers are strong. Conyat rates the buds at roughly 10 hours of playback per charge, which is a meaningful step up from Fidiso's 6–8 hours, and it pairs that with IP7 waterproofing. IP7 is a real jump over IPX5: it's built to survive immersion-level water exposure, so sweat, rain and a rinse under the tap are not a concern. For anyone training outdoors in bad weather or sweating heavily, that's the spec that matters most. Bluetooth 6.0 is also the newer generation here, and the buds use environmental noise cancellation on the mic side plus touch controls.
The trade-offs are equally clear. There's no charging case listed, no total playtime figure and no case battery capacity, so the ~10 hours per charge is your ceiling between trips to a charger — a 1.5-hour charge gets you back to full. There's no headphone jack, no multipoint claim in the sheet, and the audio spec stops at a dynamic driver with a 20 Hz–20 kHz range, with no driver size, impedance or sensitivity published. It's also a single color, black. If your priority is a case that lives in your bag and tops the buds up for days, Conyat doesn't offer that.
• Best for total battery life → Fidiso Over Ear Bud. The charging case takes you to a claimed 30–40 hours versus roughly 10 hours per charge on Conyat.
• Best for a single long session → Conyat Open-Ear Headphones. About 10 hours of playback beats Fidiso's 6–8 hours before you need a charger.
• Best for water and sweat → Conyat Open-Ear Headphones. IP7 is the tougher rating; Fidiso sits at IPX5.
• Best for the newest Bluetooth → Conyat Open-Ear Headphones. Bluetooth 6.0 versus Fidiso's 5.4.
• Best for pairing flexibility → Fidiso Over Ear Bud. The 5.4 spec supports multipoint so you can run two devices at once.
• Best for battery visibility → Fidiso Over Ear Bud. The case's dual LED display shows remaining power from 1% to 100%.
• Best for all-day lightweight wear → Conyat Open-Ear Headphones. Roughly 6.7 g per earpiece is a genuinely featherweight figure.
• Best for a complete travel kit → Fidiso Over Ear Bud. Case, Type-C cable, lanyard and manual are all in the box.
In my opinion, Fidiso Over Ear Bud is the smarter buy for most people — not because it wins every spec, but because the charging case, the 30–40 hours of total playtime, the battery display and the multipoint pairing solve the everyday problems that actually annoy open-ear users. You charge it once, toss it in a bag, and stop thinking about it.
That said, if your routine is sweat-heavy outdoor training and you hate carrying a case, I'd take the Conyat Open-Ear Headphones instead: the IP7 rating, ~10-hour single-charge runtime and 6.7 g per side are exactly what that use case needs. Check the current price on Amazon for both before deciding, since the value math shifts with whatever each is going for at the time.
Fidiso is a case-based kit with Bluetooth 5.4, 6–8 hours per charge, 30–40 hours total, a battery display and IPX5. Conyat is a case-free pair with Bluetooth 6.0, about 10 hours per charge, roughly 6.7 g per earpiece and IP7 waterproofing.
Conyat, at about 10 hours of playback. Fidiso lists 6–8 hours per charge, but its charging case extends the total to 30–40 hours, so Fidiso wins on overall time between wall charges.
For heavy sweat and rain, I'd lean Conyat because of the IP7 rating. Fidiso's IPX5 handles sweat and light rain but isn't rated for immersion. Both use open-ear designs, so you stay aware of traffic either way.
Not strictly. Conyat charges the buds themselves and gives you around 10 hours per cycle. A case like Fidiso's is about convenience — topping up on the move and stretching total runtime to 30–40 hours — so it matters most if you're away from a charger for long stretches.
