If you want all-day open-ear comfort with the longest battery life for running, cycling and gym sessions, choose LOBKIN Bone Conduction Headphones; if you need headphones you can actually wear in the pool and that play music without a phone, choose RR SPORTS IP68.
• LOBKIN biggest strength: a 25g ultra-light build with a memory titanium frame, 16mm dynamic drivers and up to 10 hours of playtime — a comfortable, stable everyday sports headphone.
• LOBKIN biggest trade-off: IPX6 only, so it handles sweat and rain but is explicitly not made for swimming or submersion.
• RR SPORTS biggest strength: true IP68 waterproofing rated for submersion up to 2 meters, plus a built-in 32GB MP3 player so you can swim with music and no phone.
• RR SPORTS biggest trade-off: shorter battery life at up to 7 hours, and Bluetooth does not work in the water — you must switch to MP3 mode when swimming.
• Who LOBKIN is for: runners, cyclists and gym-goers who want lightweight, long-lasting open-ear audio on dry land.
• Who RR SPORTS is for: swimmers, shower users and anyone who wants offline music storage built into the headphones.
LOBKIN's pitch is everyday athletic comfort. The open-ear design leaves your ear canal completely free, so traffic, footsteps and voices around you stay audible — the whole point of bone conduction for outdoor running and cycling. Powering that is a 16mm dynamic driver with a 20Hz–20,000Hz frequency range, 102dB sensitivity and 8-ohm impedance, which the spec sheet pairs with Bluetooth 6.0 for faster pairing, stronger connectivity and lower latency. There's also a built-in HD mic for calls mid-run.
The physical design is where it separates itself. At 25 grams it's genuinely light, and the skin-friendly silicone pads are meant to reduce pressure over long sessions. The memory titanium frame bends and springs back to shape, which is the feature I'd care about most if you move fast — it's the reason a headphone like this stays put without clamping down. Battery is rated at up to 10 hours with a 2-hour charge via USB-C, and the IPX6 rating covers sweat, rain and splashes. Controls are physical push buttons, and the Bluetooth range is listed at 10 meters.
So who should buy it? If your training is running, cycling, hiking or the gym, and you want the lightest, longest-lasting option here with the largest driver of the two, this is the one I'd point you to. Who should skip it? Swimmers, and anyone who wants to leave their phone behind — LOBKIN has no onboard storage and is not built for submersion.
RR SPORTS solves a different problem entirely. The headline is IP68: these are rated to survive submersion in up to 2 meters of water, with a sealed body and a nano-hydrophobic coating to keep sweat, rain and pool water out of the internals. The brand also notes they're designed to be worn with both swim caps and goggles, which is the practical detail most "waterproof" headphones get wrong. If you swim laps, this is the category that matters.
The second headline is the built-in 32GB memory. That's roughly 7,000 songs across MP3, WMA, WAV and FLAC — no phone, no signal, no problem. You load files from a computer using the included magnetic charging cable. The catch, and it's an important one: you have to use MP3 mode while swimming, because Bluetooth doesn't transmit through water. That's physics, not a defect, but it changes how you use them.
Elsewhere the spec sheet is modest but sensible. Bone conduction drivers keep your ears open to surroundings. Bluetooth 6.0 gives you a 10-meter range with better interference resistance, and battery life is rated at up to 7 hours in Bluetooth mode. The silicone build is soft and the fit is described as secure for intense activity. Weight is listed at 3.88 ounces, so it's noticeably heavier than the LOBKIN on paper.
Buy it if you swim, shower, surf, or just want a self-contained music player strapped to your head. Skip it if maximum battery life or the lightest possible fit is your priority.
Side-by-Side: Which Should You Choose?
• Best for swimming → RR SPORTS IP68. IP68 with 2-meter submersion is the decisive spec here; LOBKIN's IPX6 is not intended for water.
• Best for battery life → LOBKIN Bone Conduction Headphones. Up to 10 hours versus up to 7 hours, plus a quick 2-hour USB-C charge.
• Best for phone-free workouts → RR SPORTS IP68. The 32GB MP3 player holds thousands of tracks with no Bluetooth connection required.
• Best for long listening sessions → LOBKIN Bone Conduction Headphones. Lighter weight and softer pressure matter more the longer you wear them.
• Best for shower and pool-deck use → RR SPORTS IP68. Sweat, rain and full water exposure are all covered by the IP68 seal.
• Best for call quality → LOBKIN Bone Conduction Headphones. It's the only one of the two with a listed built-in HD mic.
• Best for a gift → RR SPORTS IP68. The brand positions it as a gift for sports-loving men, and the dual MP3/Bluetooth mode suits a wider range of recipients.
In my opinion, most people searching this comparison should buy the LOBKIN Bone Conduction Headphones. It's lighter at 25g, lasts up to 10 hours instead of 7, uses bigger 16mm dynamic drivers, adds a mic for calls, and its IPX6 rating covers the sweat and rain that 90% of workouts involve. I'd only steer you to the RR SPORTS IP68 if you genuinely swim or shower in your headphones — and in that case, the 2-meter IP68 rating and 32GB MP3 player make it the only real option of the two. Pick by activity, not by hype: dry land, go LOBKIN; water, go RR SPORTS.
Yes, and it isn't close. RR SPORTS is rated IP68 for submersion up to 2 meters, while LOBKIN is IPX6 — fine for sweat and rain, but not designed to be underwater. If swimming is your main activity, that single difference decides it.
No. The manufacturer specifically notes that Bluetooth mode doesn't work in water and that you should switch to MP3 mode when swimming. Load your music into the 32GB memory first, then leave the phone on the pool deck.
LOBKIN, with up to 10 hours of playtime and a 2-hour charge time. RR SPORTS is rated at up to 7 hours in Bluetooth mode. For long rides or back-to-back sessions, LOBKIN gives you more headroom.
Yes. Specs tell you which pair fits your activity, but value depends on what each is going for right now. Use the price button on this page to compare current pricing on Amazon before you commit — a small gap might make the water-friendly pair worth it even if you only swim occasionally.
