How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, dedicated storage shell that protects a pair of Shokz-style bone conduction headphones between workouts, choose Hermitshell Hard Case; if you need the actual air conduction headphones for a kid to wear, listen and stay aware of traffic, choose Golvery Kids.
• Hermitshell Hard Case — biggest strength: a molded EVA shell built specifically around AfterShokz/Shokz open-ear headphones (AS650, AS800, Titanium Mini, OpenRun Pro), with a 5.2 x 4 x 1.5 inch interior that cradles the headband shape and guards against bumps, dents and scratches.
• Hermitshell Hard Case — biggest trade-off: it is case only. No headphones, no cable, no accessories, and it is not water resistant, so it protects from impact, not from being left out in the rain.
• Golvery Kids — biggest strength: an actual pair of open-ear air conduction headphones for children, at 13 g with a bendable memory titanium alloy frame, Bluetooth 5.3, a built-in ENC mic and about 10 hours of playtime.
• Golvery Kids — biggest trade-off: the 85 dB volume ceiling is a safety feature, not a hi-fi feature, and it pairs with one device at a time — you cannot stream from two phones simultaneously.
• Who each pick is for: Hermitshell Hard Case → anyone who already owns Shokz-style bone conduction headphones and wants a hard travel box for them. Golvery Kids → parents buying a first open-ear headphone for a child over three.
The Hermitshell Hard Case is a single-purpose product: a hard travel storage case for open-ear bone conduction headphones in the AfterShokz/Shokz family. The shell is EVA — ethylene vinyl acetate — which is the same class of foam-like material used in a lot of semi-rigid tech cases. It has some give, but it holds its shape, so pressure from a backpack or a gym bag does not translate straight onto the headband. The interior measures 5.2 x 4 x 1.5 inches, and the maximum compatible device size is listed at 5.2 inches, which tells you the cavity was cut around the specific footprint of these headphones rather than being a generic pouch.
What it does best is travel logistics. If you carry Shokz OpenRun Pro or an older AS650 around in a tote or a rucksack, the weak point is the band and the transducer arms — they get squashed against water bottles, laptop edges and keys. A molded case solves that. It also gives you one obvious place to drop the headphones so you always know where they are, which matters more than people admit.
Who should buy it: someone who already owns compatible Shokz/AfterShokz headphones and treats them as gear rather than a desk accessory. Commuters, runners who toss a bag in a car trunk, cyclists who want the headphones protected between rides.
Who should skip it: anyone who does not yet own bone conduction headphones — this is case only, and the device and accessories are sold separately. Also skip it if you need weather protection. The case is listed as not water resistant, so it is impact protection, not a dry bag. And if your headphones are not in the compatible list, the fit is a gamble — this is a molded case, not a universal one. Check the current price on Amazon before you commit, since that is the one variable I cannot speak to here.
The Golvery G03 is the other half of the story — the actual hardware. It is an open-ear air conduction headphone aimed at children, and the design choices make that obvious. The headband uses skin-friendly soft silicone over a memory titanium alloy core, and it is 360° bendable without deforming. Anyone who has handed electronics to a seven-year-old knows why that matters. It weighs 13 g, which is light enough that a kid is unlikely to complain about it after ten minutes.
The headline safety feature is the 85 dB volume limit. Air conduction sits outside the ear canal, so the child hears both the audio and the world around them — traffic, a parent calling, a teacher. Combined with the volume ceiling, that is the entire pitch: awareness plus a hard cap on loudness. For a kid walking to school or riding a bike beside an adult, that combination is more useful than isolation.
On the tech side, it runs Bluetooth 5.3 with a 10 meter range, pairs with phones, tablets, Kindles, Chromebooks, MacBooks and PCs, and charges over USB-C in about 1.5 hours for roughly 10 hours of playback. There is a built-in mic with an ENC noise-reduction algorithm for calls, though call answer and hang-up have to be handled on the connected device for third-party chat apps. It is IPX5, so sweat, splashes and light rain are fine — but not swimming or submersion. The frame is also designed to work with glasses and a helmet.
Who should buy it: parents of kids over three who want an open-ear option for online classes, travel, hiking, running or cycling, and who value the volume limit over bass. Adults with small heads or a preference for ultra-light open-ear fit will also find it wearable, since Golvery states it is designed for kids and adults.
Who should skip it: anyone who wants deep, isolating sound. Open-ear air conduction is deliberately leaky — that is the point. Also skip it if you need multipoint pairing, because it plays from one device at a time. And skip it for swimming, since IPX5 is splash resistance, not waterproofing.
• Best for protecting headphones you already own → Hermitshell Hard Case. EVA shell, molded interior, 5.2 x 4 x 1.5 inches.
• Best for a child who needs headphones → Golvery Kids. 13 g, bendable titanium alloy frame, 85 dB limit.
• Best for hearing safety → Golvery Kids. The 85 dB cap plus open-ear awareness is the whole design intent.
• Best for battery and charging convenience → Golvery Kids. About 10 hours playback, roughly 200 hours standby, 1.5-hour USB-C charge.
• Best for travel durability against impact → Hermitshell Hard Case. That is literally its only job, and it does it without electronics to fail.
• Best for calls → Golvery Kids. Built-in mic with ENC noise reduction, with the caveat that chat-app call control happens on your device.
• Best for sweaty or rainy outdoor use → Golvery Kids. IPX5 resists sweat, splashes and rain; the Hermitshell case is not water resistant.
• Best for glasses and helmet wearers → Golvery Kids. The ergonomic frame is stated as compatible with both.
• These are not competitors. One stores headphones, one is headphones. Buy the Golvery if you need the hardware; buy the Hermitshell if you need a home for hardware you already have.
In my opinion, most people searching this comparison actually need the Golvery Kids, because it is the product that does something — it plays audio, it caps volume at 85 dB, and it stays on a kid's head during a bike ride. I would buy it for a child over three without hesitation, understanding that open-ear sound is a feature and not a compromise. I would only buy the Hermitshell Hard Case if I already owned compatible Shokz or AfterShokz headphones and wanted to stop them getting crushed in a bag. They solve different problems, so the honest answer is that the right pick depends entirely on whether you are missing the headphones or missing the box.
how to wear air conduction headphones
Air conduction headphones like the Golvery G03 rest outside the ear canal rather than inside it. The ear hooks sit over the top of your ear and the transducer arm hovers just in front of the ear opening, so the frame — not the eartip — holds the headphone in place. Golvery states the G03 frame is compatible with glasses and a helmet.
how to use air conduction headphones
Power the G03 on with Bluetooth active on your device, then pair over Bluetooth 5.3 within a 10 meter range. Volume, playback and pairing are handled by touch and manual earcup controls on the headset, while call answer and hang-up in third-party chat apps must be done on the connected phone or computer. It plays from one device at a time and shuts off automatically after about 10 minutes disconnected.
how to put on air conduction headphones
Slide the band behind your head, then guide each ear hook down over the top of your ear so the arm sits in front of the ear opening, not on it. The Golvery G03 uses a memory titanium alloy core that bends 360° without deforming, so you can open the frame slightly to fit and it springs back into shape.
how to pair goodmans air conduction headphones
Goodmans headphones are not covered by either of these data sheets, so I cannot give model-specific steps. The general method for any Bluetooth air conduction headphone is the same as the G03: enable Bluetooth on your device, power the headphones on and put them in pairing mode, then select them from your device's Bluetooth list. For PC, laptop or Switch connections, confirm the device actually has Bluetooth first.
