How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want marathon battery life and a traditional over-ear fit with app-tuned sound, choose Amazon Renewed Skullcandy Hesh 360; if you need open-ear awareness, an adjustable secure fit for movement, and AI-powered features in a true-wireless earbud, choose 1Mii E35.
• Amazon Renewed Skullcandy Hesh 360 — biggest strength: Up to 100 hours of battery with an 8-hour top-up from a 10-minute Rapid Charge, plus multipoint pairing and app-based EQ.
• Amazon Renewed Skullcandy Hesh 360 — biggest trade-off: It's a renewed unit with a 90-day limited warranty, and the over-ear, noise-isolating design blocks out your surroundings rather than letting them in.
• 1Mii E35 — biggest strength: An open-ear hook design with up to 60° of adjustment per ear, 16.2mm dynamic drivers, 4-mic call clarity, and 45 hours total playtime with the case.
• 1Mii E35 — biggest trade-off: Open-ear audio inherently leaks in more ambient sound, and total playtime depends on topping up via the charging case.
• Who each pick is for: The Hesh 360 suits long-session listeners, travelers and desk workers who want one charge to last days. The 1Mii E35 suits runners, commuters and anyone who needs to stay aware of their environment while listening.
The Hesh 360 is a wireless over-ear headphone built around endurance. The headline figure is up to 100 hours of battery life, and the Rapid Charge feature gives you a full 8 hours of listening from just a 10-minute charge. In practice that means you can leave the house for a week of commutes, workdays and workouts without ever thinking about a cable. If you're the kind of person who resents charging something every night, that number alone reframes the whole purchase.
Around that core, the Hesh 360 layers in genuinely useful features. Adjustable Stay-Aware Mode lets you dial in how much of the outside world you let through, controlled through the Skullcandy App — so you can go fully isolated on a noisy train and then open things up when you're walking a busy street. Multipoint pairing connects two devices at once, which is the difference between taking a laptop call and switching back to your phone without repairing. The Clear Voice Smart Mic isolates your voice for calls, and in-app EQ gives you three presets (Music, Bass Boost, Podcast) plus a custom 5-band EQ. There's also a Low-Latency Audio mode that matters if you game or watch video and hate lip-sync drift, and natural voice sidetone so your own voice sounds normal on calls rather than muffled.
The design is flat-folding and collapsible, which makes it easy to toss in a bag, and it ships with a detachable 3.5mm cable — so you have a wired fallback if you ever need one. The enclosure mixes faux leather, metal, plastic and silicone, and the unit weighs 0.24 kg. Controls are physical push buttons rather than touch, which some people strongly prefer because you can find them by feel and they don't misfire.
Who should skip it: people who need to hear traffic or coworkers while listening, anyone who prefers the featherweight feel of earbuds, and shoppers who want the longest possible warranty — this is a renewed item backed by a 90-day limited warranty.
1Mii E35: Who It's For
The 1Mii E35 takes the opposite approach. Instead of sealing you off from the world, the open-ear design deliberately lets surrounding sound in. That's the entire point: you get music, podcasts or calls while still hearing cars, announcements, colleagues and your own environment. For runners, cyclists, commuters on busy platforms and office workers who need to respond when someone walks up, that awareness is a safety and practicality feature, not a compromise.
The fit is where the E35 does its most interesting engineering. Flexible ear hooks adjust through up to 60° of multi-angle movement, so they adapt to different ear shapes and sizes while staying secure during movement without pressing hard against your ear. The ear placement is open-ear with a hook shape, and the whole thing weighs 110 g including the case. That combination — secure but pressure-free — is what makes them plausible for sport, all-day work and daily wear in the same pair.
Sound comes from an oversized 16.2mm dynamic driver, with a frequency range of 20 Hz to 20 kHz, 22 ohm impedance, 42 dB sensitivity, and acoustic tuning aimed at reducing the sound loss that open designs typically suffer from. You won't get the isolation of a sealed over-ear, but the driver size is doing real work to keep bass and vocals present. Calls are handled by four microphones with noise reduction, and the Bluetooth 6.0 connection is a modern, stable spec with quick pairing.
Battery is 18 hours per charge and up to 45 hours total with the charging case, which itself takes 1.5 hours to charge. Control is unusually flexible: touch controls, physical buttons, and app support for EQ and function customization. And then there's the AI layer — on-the-go AI voice chat, English practice, contextual learning and real-time translation across 103 languages. That's a genuinely different feature set from a conventional headphone. The E35 also ships with a 12-month warranty.
Who should buy it: runners, gym-goers, cyclists, commuters, and anyone who wants ambient awareness plus app control, strong call mics and a translation/assistant layer. It also suits people who dislike the pressure of in-ear tips or the bulk of over-ear cups.
Who should skip it: listeners who want maximum isolation and deep passive noise blocking, and anyone who wants a single charge to cover several days without the case.
• Best for battery life → Amazon Renewed Skullcandy Hesh 360. Up to 100 hours, plus 8 hours from a 10-minute charge.
• Best for situational awareness → 1Mii E35. The open-ear design is built specifically to keep you connected to your surroundings.
• Best for long calls and meetings → Amazon Renewed Skullcandy Hesh 360. The Clear Voice Smart Mic and sidetone are aimed squarely at voice quality, and multipoint keeps two devices live.
• Best for running, cycling and the gym → 1Mii E35. Adjustable hooks up to 60° and a pressure-free secure fit are made for movement.
• Best for on-the-go AI features and translation → 1Mii E35. Real-time translation across 103 languages and AI voice chat are unique to it.
• Best for gaming and low-latency video → Amazon Renewed Skullcandy Hesh 360. The dedicated Low-Latency Audio mode is designed for exactly that.
• Best for switchable isolation → Amazon Renewed Skullcandy Hesh 360. Adjustable Stay-Aware Mode lets you choose how much of the outside world you let in.
• Best for a wired fallback option → Amazon Renewed Skullcandy Hesh 360. It includes a detachable 3.5mm cable; the E35 has no headphone jack.
If I had to pick one, I'd buy the 1Mii E35 for most people's day-to-day life. In my opinion, the open-ear awareness, the adjustable hook fit, the 4-mic call setup and the AI layer cover more real situations — running, commuting, working, taking calls on the move — than a single sealed headphone can. That said, if your priority is raw endurance and isolation — days of battery, multipoint between laptop and phone, app EQ and a wired backup — I'd choose the Amazon Renewed Skullcandy Hesh 360 without hesitation. The E35 wins on flexibility and features; the Hesh 360 wins on stamina and focus.
It's a renewed product backed by a 90-day limited warranty, and it still delivers the full feature set: up to 100 hours of battery, Rapid Charge, multipoint, app EQ and a detachable 3.5mm cable. If those specs match what you need, check the current price on Amazon and weigh it against the shorter warranty.

The 1Mii E35, clearly. Its open-ear design keeps you aware of traffic and surroundings, and the 60° adjustable hooks plus pressure-free fit are built for movement. The Hesh 360 is over-ear and noise-isolating, which is the opposite of what you want on a busy road.
Both are designed for voice. The E35 uses four microphones with noise reduction and Environmental Noise Cancellation; the Hesh 360 uses a Clear Voice Smart Mic with sidetone. The E35's extra mics suit noisy, mobile environments, while the Hesh 360's sidetone and multipoint suit long desk-based calls.
