How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds with a huge charging case that doubles as a phone power bank and true in-ear noise isolation, choose Xmythorig Ultimate True; if you need open-ear awareness for cycling and running plus a much lighter fit, choose Rakklor Bone Conduction Headphones.
• Xmythorig Ultimate True — biggest strength: a 3300 mAh charging case that the brand says delivers up to 25 full recharges of the buds and can also top up your phone, plus an IPX7 waterproof rating on the earbuds themselves.
• Xmythorig Ultimate True — biggest trade-off: in-ear sound isolation means you block out traffic and surroundings, the charging case is not waterproof, and the stated average playtime is only around 5 hours per charge (7 hours to recharge the case).
• Rakklor Bone Conduction Headphones — biggest strength: open-ear bone conduction design keeps your ears unblocked so you stay aware of traffic and voices, in a 26 g frame rated IPX5 for sweat and light rain.
• Rakklor Bone Conduction Headphones — biggest trade-off: no noise isolation at all, no charging case in the box, and a plastic open-ear frame that won't suit anyone who wants deep bass or a sealed, quiet listening bubble.
• Who each one is for: Xmythorig for gym-goers, commuters and travelers who want sealed sound and battery insurance; Rakklor for runners, cyclists and hikers who prioritize hearing the world around them.
The Xmythorig Ultimate True is a true-wireless in-ear set built around convenience rather than minimalism. The headline feature is the charging case: a 3300 mAh battery built into the case that the brand says provides up to 25 full charges for the earbuds and can also be used as a power bank for your phone. That's the kind of design that appeals to someone who is away from a wall outlet for long stretches — a festival weekend, a long-haul flight, a camping trip, or a workday where the phone is already running low by mid-afternoon. Pairing is deliberately simple: lift both buds out of the case and they connect to each other automatically, then you pair once through your phone's Bluetooth menu. After that, the brand says they reconnect on their own when you take them out again.
On the audio side, these are dynamic-driver in-ears with 32 ohm impedance and touch controls on the earbud. The brand describes noise cancellation technology that reduces ambient noise and echo, which is really sound isolation plus call processing rather than active noise cancellation — worth knowing if you expect ANC. That isolation is the point for a lot of buyers: in a gym, on a bus, or in a noisy office, a sealed in-ear fit is what lets you hear the bass and detail in your music. The IPX7 rating on the earbuds covers sweat and rain, and the ergonomic in-ear shape with ear wings is designed to stay put during running and workouts. The brand explicitly notes the charging case is not waterproof, and warns against fast chargers above 5V/1A, so keep the case dry and use a standard charger.
Who should buy it: anyone who wants sealed in-ear sound, touch controls, a genuinely enormous battery reserve, and the option to charge a phone from the same case. Who should skip it: cyclists and runners who need to hear traffic, anyone who dislikes things sitting inside the ear canal, and anyone who wants a waterproof case or expects active noise cancellation.
The Rakklor Bone Conduction Headphones take the opposite approach: nothing goes in your ear. A bone conduction driver sits against your cheekbone and sends sound through vibration, leaving the ear canal completely open. If you have ever ridden a bike with earbuds in and felt uneasy about the car you couldn't hear, that's the exact problem this design solves. The brand leans into that — the open-ear fit is framed around hearing traffic, other cyclists and voices while you keep listening to music, podcasts or calls. It also means no in-ear pressure and no ear fatigue after long sessions, which matters if you wear headphones for hours of yard work or a long hike.
The rest of the spec sheet is built for movement. It weighs 26 g, with a flexible neckband and ergonomic ear hooks that are meant to stay secure during active use. Bluetooth 5.4 handles the connection with a stated range of about 33 ft/10 m, and there's a built-in mic with on-frame controls for volume, music and hands-free calls — a push-button and touch combination rather than a single control scheme. Battery life is rated at up to 20 hours per charge, with USB-C and a quick-charge claim of roughly 90 minutes of playback from a 10-minute top-up, and a full charge taking about 2 hours. The IPX5 rating covers sweat and light rain, though the brand is clear it is not for swimming or full immersion.
Side-by-Side: Which Should You Choose?
• Best for hearing your surroundings → Rakklor Bone Conduction Headphones. Open-ear bone conduction with no noise control is designed to keep traffic and voices audible.
• Best for sealed, immersive listening → Xmythorig Ultimate True. In-ear dynamic drivers with sound isolation block out the room instead of letting it in.
• Best for battery insurance → Xmythorig Ultimate True. The 3300 mAh case is rated for up to 25 full recharges and can charge your phone too.
• Best for long single-charge sessions → Rakklor Bone Conduction Headphones. Up to 20 hours of continuous playback versus roughly 5 hours average per charge on the Xmythorig buds.
• Best for all-day comfort and low weight → Rakklor Bone Conduction Headphones. At 26 g with ear hooks and no in-ear pressure, it's built for hours of wear.
• Best for gym swea t and rain on the buds → Xmythorig Ultimate True. IPX7 on the earbuds beats IPX5, but remember the case is not waterproof.
• Best for quick top-ups → Rakklor Bone Conduction Headphones. A 10-minute USB-C charge is claimed to give about 90 minutes of playback.
• Best for phone charging on the road → Xmythorig Ultimate True. The case doubles as a power bank; the Rakklor has no case at all.
In my opinion, the deciding question is whether you want your ears open or sealed. If you run, ride or hike near traffic, I would buy the Rakklor Bone Conduction Headphones: the open-ear design, 26 g frame, 20-hour battery and quick-charge USB-C all point at exactly that use case, and the included earplugs let you add isolation when you want it. If you want sealed sound, touch controls and a case that can rescue your phone, I would buy the Xmythorig Ultimate True instead. Neither is "better" in the abstract — they solve different problems. Check the current price on Amazon for each before you commit, since that gap shifts the math.
For road running where you need to hear cars, the Rakklor's open-ear design is the safer pick. For treadmill or gym running where you want sealed sound and a secure IPX7 in-ear fit, the Xmythorig Ultimate True makes more sense.
No. The spec sheet lists noise control as none — that's the trade-off for the open-ear design. The included silicone earplugs are the brand's answer when you want to block out noise and get more bass.
The Rakklor is rated at up to 20 hours per charge with a 2-hour recharge. The Xmythorig buds are rated around 5 hours average per charge, but the 3300 mAh case recharges them up to 25 times, so total listening time is far longer.
The earbuds are IPX7, so sweat and rain are fine, but the brand says the charging case is not waterproof and warns against hot water and shampoo. Treat them as workout-and-weather earbuds, not swimming headphones. The Rakklor is IPX5 and also not for swimming or immersion.
