If you want featherweight, wireless, sweat-proof open-ear buds for running and the gym, choose Ttbesmi Purple Out; if you need a wired, plug-and-play open-ear set with a boom-free inline mic and volume controls for calls, gaming and desk work, choose GZCRDZ Open-Ear Headphones.
• Ttbesmi Purple Out — biggest strength: a truly wireless Bluetooth 5.3 design at just 18.14 g (about 0.3 oz), with an IPX5 nano-coating, ENC dual-mic calls and a 300 mAh charging case. This is the one you grab for a run.
• Ttbesmi Purple Out — biggest trade-off: the battery is short. Ttbesmi lists roughly 4 hours of playtime at 50% volume and about 1 hour to charge — a single-session headphone, not an all-day one.
• GZCRDZ Open-Ear Headphones — biggest strength: a 16 mm composite-film driver, rotatable silicone ear hooks, an inline noise-canceling mic with volume and track controls, and no battery to worry about because it draws power from your device over its Type-C plug.
• GZCRDZ Open-Ear Headphones — biggest trade-off: it's wired. The 1.3 m braided cable means you're tethered to your phone or laptop, and there's no Bluetooth at all.
• Who each is for: Ttbesmi Purple Out for wireless outdoor athletes who want zero cables; GZCRDZ Open-Ear Headphones for wired listeners who want controls at their fingertips and never want to think about charging.
Ttbesmi's whole pitch here is "out of ear, not in ear." The earpieces hang over the ear rather than sitting inside the canal, so your ear stays open and you keep hearing traffic, footsteps, teammates and whatever else is happening around you. For anyone who has ever pulled an in-ear bud out mid-run because it felt unsafe or uncomfortable, that's the entire point. Ttbesmi also claims directional sound transmission to push audio toward the ear without leaking much — the spec sheet lists a bone conduction driver with a 20 Hz–20 kHz range and 20 ohm impedance.
The weight is the standout number: 18.14 g for the pair. That's the kind of figure that matters when you're wearing something for an hour of jogging, and it pairs with a skin-friendly ABS build the brand describes as non-slip and non-allergenic. Add IPX5 waterproofing and a nano-coating, and this is clearly built around sweat and light rain rather than desk duty. The 300 mAh charging case tops them up in about an hour, and Bluetooth 5.3 gives you a roughly 10 m wireless range.
Buy it if you want a wireless, ultra-light open-ear headphone for running, hiking, gym work and commutes where you need to hear your surroundings. Skip it if battery life is your priority — Ttbesmi rates playtime at about 4 hours at 50% volume, so long days or flights will need charging breaks. Skip it too if you want physical buttons on a cable; this is a media-control remote with a charging case and no headphone jack.
GZCRDZ takes the opposite approach: same open-ear concept, but wired and built around control. It uses a rotatable ear hook made of soft silicone that the brand says fits a range of ear shapes without pressure, keeping the driver outside your canal so you stay aware of your surroundings. The audio hardware is a 16 mm composite-film speaker with ACS 3D acoustic resonance and a 20 Hz–20 kHz response — a notably large driver for this category, which is what GZCRDZ leans on for its bass and treble claims.
The practical difference is the inline module. There's a noise-canceling mic for calls plus inline controls for volume, play/pause, track skipping and answering or rejecting calls — all without touching your phone. The cable is 1.3 m of braided TPE, the net weight is 30 g, and the connectors are a Type-C plug on one end and a 3.5 mm audio jack on the other, which broadens what you can plug into: phones, tablets, laptops, MP3 players. A one-year warranty is listed, and the company markets it for gym, outdoor sports, commuting and office use.
Buy it if you want wired reliability, an inline mic and volume control, and a fit that stays put during cycling, running or long desk sessions. Skip it if you want to move freely — the cable is the trade-off — or if your phone has no headphone jack and no adapter. Also note it's a single black colorway, so if you want something more expressive, that's not this.
• Best for wireless freedom → Ttbesmi Purple Out. Bluetooth 5.3, 10 m range, no cable to snag on gym equipment.
• Best for battery anxiety → GZCRDZ Open-Ear Headphones. It's wired, so there's no playtime limit and nothing to recharge.
• Best for long sessions → GZCRDZ Open-Ear Headphones. Ttbesmi's ~4 hours at 50% volume is a short window; a wired set just keeps going.
• Best for workouts and sweat → Ttbesmi Purple Out. IPX5 plus a nano-coating is a stated feature; GZCRDZ doesn't list a water-resistance rating.
• Best for calls and controls → GZCRDZ Open-Ear Headphones. Inline mic plus volume, playback and call buttons you can find by feel.
• Best for light weight → Ttbesmi Purple Out. 18.14 g versus roughly 30 g, and no cable drag on top of it.
• Best for multi-device flexibility → GZCRDZ Open-Ear Headphones. Type-C and 3.5 mm compatibility covers phones, tablets, laptops and MP3 players.
• Best for color choice → Ttbesmi Purple Out. It's offered in purple, while GZCRDZ comes in black.
In my opinion, the pick comes down to one question: can you live with a cable? If you can't, buy the Ttbesmi Purple Out. It's the lighter, wireless, sweat-resistant option, and for running or the gym the open-ear awareness plus 18.14 g of weight is exactly what you want. If you'd rather have inline controls, an integrated mic and never think about charging, I'd take the GZCRDZ Open-Ear Headphones — the 16 mm driver and rotatable hooks make it the more versatile everyday set for calls, gaming and desk work. Both are legitimate open-ear designs; they just solve different problems.
how do non ear headphones work
They sit outside your ear canal instead of plugging into it. Sound is pushed toward your ear by the driver — a bone conduction driver in the Ttbesmi Purple Out, or a 16 mm composite-film speaker in the GZCRDZ — while your canal stays open, so ambient sound comes through.
what are non in ear headphones called
They're usually called open-ear headphones, and you'll also see them described as out-of-ear, over-the-ear, air conduction or bone conduction headphones. Both products here fall in that family: Ttbesmi's model uses a bone conduction driver, while GZCRDZ uses a traditional speaker aimed at your ear.
how to wear in ear headphones
This pair isn't in-ear, but the hook logic still applies: the earpieces rest over your ear with the driver facing the canal, and the hook holds them in place. Ttbesmi's are ear-hanging and wireless; GZCRDZ's use rotatable silicone hooks, and its 1.3 m cable runs down to your device.
what are the best open ear headphones
There isn't one answer — it depends on whether you want wireless or wired. For wireless workouts, I'd point to the Ttbesmi Purple Out for its 18.14 g weight and IPX5 rating. For wired calls and desk use, the GZCRDZ Open-Ear Headphones win on inline controls and its 16 mm driver.
