If you want long, uninterrupted listening sessions with an over-ear fit you barely have to think about, choose Skullcandy Hesh 3; if you need a sweat-proof, hook-secured pair that stays put through runs and gym sessions, choose Rulefiss Earbuds.
These two aren't really rivals — they're built for different bodies and different days. One is a collapsible over-ear that treats battery life as its headline. The other is a sport-first in-ear with earhooks, a waterproof rating and a charging case. The right answer comes down to where and how you actually wear your headphones.
• Skullcandy Hesh 3 — biggest strength: up to 22 hours of battery life plus a rapid-charge feature that gives you roughly 4 hours of playback from a 10-minute top-up, all in a foldable over-ear design.
• Skullcandy Hesh 3 — biggest trade-off: it's a Bluetooth over-ear with a plastic enclosure and sound-isolating (not active noise-cancelling) design, so loud environments leak in and it isn't built for sweat or rain.
• Rulefiss Earbuds — biggest strength: a sport-focused build with flexible 45° earhooks, IP7 waterproofing, 13mm drivers and a charging case that extends total playtime to 48 hours.
• Rulefiss Earbuds — biggest trade-off: it's an in-ear earhook design, so you're relying on silicone tips for seal and fit, and the stated frequency range tops out lower than the Hesh 3's.
• Who should pick the Hesh 3: desk workers, commuters and home listeners who want one pair on their head for hours.
• Who should pick the Rulefiss Earbuds: runners, gym-goers and anyone who needs their audio to survive sweat and movement.
The Hesh 3 is a classic over-ear wireless headphone, and its whole pitch is stamina. Skullcandy rates it at up to 22 hours of total battery life, and the rapid-charge claim is genuinely useful: 10 minutes of charging gets you about 4 hours of playback. If you're the kind of person who grabs headphones on the way out the door and forgets to plug them in, that math matters more than almost any spec on the sheet.
It also folds. The collapsible design and a removable aux cable in the box mean it packs down and can still work wired if you want a cable connection. There's a built-in microphone for calls, and it ships with a micro USB charging cable and a two-year manufacturer warranty.
Buy it if you want an over-ear you can wear for long stretches, value battery life and quick top-ups, and like the idea of a foldable pair with physical buttons.
Skip it if you need waterproofing, want active noise cancellation, or plan to wear your headphones while running or sweating heavily. It's an indoor-and-commute product, and the plastic enclosure and over-ear shape reflect that.
Rulefiss Earbuds: Who It's For
The Rulefiss Q38 is built around movement. The defining feature is the 45° earhook structure — a soft, flexible hook that curves around the back of your ear so the bud doesn't pop out mid-stride. Each earbud weighs about 7 grams, and you get three sizes of silicone tips (S/M/L) to dial in the seal. If you've ever had a standard bud fall out on a treadmill, this is the design that fixes it.
Durability for sweat and weather is the other headline. The Q38 carries IP7 waterproofing, which is what lets it survive rain and heavy perspiration during workouts. That's a category of protection the Hesh 3 simply doesn't claim, and it's the single biggest reason a runner would pick this pair.
Sound comes from 13mm graphene moving-coil drivers with AAC/SBC decoding, covering a 20 Hz–20,000 Hz range on the marketing side (the spec sheet lists a 20 kHz response and a 20 Hz–10,000 Hz frequency range field). The sheet also cites a 30-millisecond latency figure and Bluetooth 5.3 with a 15-meter range, which is the modern standard for a stable, low-lag connection. Two microphones with CVC 8.0 noise handling are there for calls.
Battery is handled by the case. A single charge gives roughly 6–8 hours, and the 800mAh case pushes total playtime to 48 hours, with a dual LED display showing the percentage so you're never guessing. A full case recharge takes about 1.5 hours over USB-C. Controls are touch-based, including voice-assistant activation, and each bud can be used independently — though the pair can't connect to two devices at once. Compatibility covers iOS 9.0 / Android 5.0 and up.
Buy it if you train, run or commute on foot and want a locked-in fit, waterproofing and a case that keeps you going for days.
Skip it if you prefer the feel of a full over-ear cup, want a wired option, or need to stay connected to two devices simultaneously.
• Best for battery life → Skullcandy Hesh 3. 22 hours on a single charge is enough for multi-day light use without a case in the equation.
• Best for total playtime with a case → Rulefiss Earbuds. The 800mAh case stretches things to 48 hours, and the LED display tells you exactly where you stand.
• Best for workouts and running → Rulefiss Earbuds. Earhooks, IP7 waterproofing and 7g buds are made for sweat and motion.
• Best for long desk or couch sessions → Skullcandy Hesh 3. Over-ear cups and physical buttons are more comfortable for hours at a stretch.
• Best for quick top-ups → Skullcandy Hesh 3. 10 minutes for about 4 hours is the more forgiving option when you're in a hurry.
• Best for wired backup → Skullcandy Hesh 3. It ships with a removable aux cable, so you're not stranded if the battery dies.
• Best for a secure in-ear seal → Rulefiss Earbuds. Three tip sizes plus the earhook structure give you more fit adjustment.
• Best for voice assistants and touch control → Rulefiss Earbuds. Touch panels and Siri/Google Assistant activation are built in.
In my opinion, most people should pick based on where the headphones live, not which spec sheet looks longer. If your listening happens at a desk, on a sofa or on a commute, I'd buy the Skullcandy Hesh 3 — the 22-hour battery, rapid charge, foldable frame and removable aux cable make it the more comfortable, more forgiving everyday pair. If your listening happens while moving and sweating, I'd buy the Rulefiss Earbuds — the earhooks and IP7 rating are the two features that actually decide whether a pair survives your routine. Neither is a compromise pick; they just belong to different parts of your day.
FAQ
The spec sheet lists active noise cancellation as the noise-control type, alongside a sound-isolating earhook fit. The Hesh 3, by contrast, relies on passive sound isolation only — there's no ANC claim on its sheet.
That's exactly what they're designed for. The 45° earhooks, 7g per-bud weight, three tip sizes and IP7 waterproofing all point to sport use, and they're rated to handle sweat and rain.
Yes. It ships with a removable aux cable, so you can run it wired — which also means you can keep listening if the battery runs out. The Rulefiss pair has no headphone jack.
If you need one pair for everything, I'd lean toward the Rulefiss Earbuds for their versatility across workouts and commuting, and toward the Hesh 3 if your priority is comfort and battery life at a desk. Check the current price on Amazon for both before deciding.
