If you want in-ear earbuds with ear hooks and a charging case that keeps you moving for days, choose FK Trading Huawei Mate 30; if you need open-ear headphones that leave your ear canal open while you ride or run, choose RSPK Open Ear Headphones. Both carry an IPX6 waterproof rating, so sweat and rain are handled either way — the real decision comes down to fit style, battery strategy, and how aware you want to stay of traffic around you.
• FK Trading Huawei Mate 30 — biggest strength: Ear-hook in-ear design with three ear-tip sizes (S/M/L), Bluetooth 5.3, four microphones with noise canceling, and a 500mAh case that pushes total playtime to 48 hours.
• FK Trading Huawei Mate 30 — biggest trade-off: It seals your ear canal, so you get passive noise blocking but less awareness of your surroundings, and the specs list only one color (black).
• RSPK Open Ear Headphones — biggest strength: Open-ear placement that rests outside the ear canal for situational awareness, plus newer Bluetooth 5.4 and a 2-year warranty.
• RSPK Open Ear Headphones — biggest trade-off: The spec sheet is thin on battery numbers and mic details, so there's less to go on beyond the core feature list.
• Pick FK Trading Huawei Mate 30 if you want a locked-in fit, long total playtime and clear calls for gym, treadmill or indoor training.
• Pick RSPK Open Ear Headphones if you prioritize hearing your environment — cycling, road running, or long outdoor sessions where you want your ears unplugged.
This one is a classic sports earbud built around retention. The ear hooks are soft and flexible, and because they wrap over the ear rather than relying on the tip alone, the fit is meant to hold through running, lifting and any movement where regular in-ears tend to work loose. FK Trading also includes three sizes of silicone tips, which matters more than people think — the seal you get from a correctly sized tip is what gives you both the bass response and the passive noise blocking described in the specs.
Battery is the headline number here. The buds themselves are rated at 9 hours of playback, and the 500mAh charging case extends that to a combined 48 hours. Recharging the case over USB-C takes about 1.5 hours. In practice that combination suits someone who trains most days and doesn't want to think about charging — a few sessions between top-ups is realistic, and the case's LED display keeps the state of charge visible.
Call quality gets unusual attention for a sports bud: four microphones with environmental noise canceling are on board, paired with Bluetooth 5.3 for a more stable connection. If you take work calls between sets or run a business line while walking, that's a meaningful spec. Compatibility is broad — iPhone, Android phones including the Galaxy S and Note lines, iPads and other Bluetooth devices. The build is polycarbonate in black.
Skip it if you need to stay fully aware of your surroundings — the in-ear seal plus noise blocking works against that — or if you dislike the feeling of something seated inside your ear canal for a full workout.
The RSPK set takes the opposite approach. Nothing goes into your ear canal. The drivers sit outside the ear, which is the whole point of an open-ear design: you hear your music and you hear the car behind you. For cyclists, road runners and anyone training near traffic or on shared paths, that's not a small detail — it's the reason to buy this style in the first place.
RSPK lists Bluetooth 5.4, which is the newer wireless specification of the two here, and the model is pitched squarely at cycling, running and workouts. The finish is gunmetal, and the package includes a user manual. Notably, it carries a 2-year warranty description — a longer stated coverage window than the FK Trading listing provides, and worth weighing if you're hard on your gear.
What you won't find in the spec sheet: a stated playtime figure, a case capacity, or microphone details. The feature list calls out "sports long playtime" but doesn't quantify it. That's not a red flag on its own — plenty of open-ear models run for many hours — but it does mean you're buying this one for its design philosophy and Bluetooth version rather than a headline battery number you can compare directly.
Buy it if open-ear awareness, the newer Bluetooth spec and the longer warranty are your priorities. Skip it if you want the passive isolation, the confirmed 48-hour total playtime, or the multi-mic call setup that the FK Trading set documents in detail.
Side-by-Side: Which Should You Choose?
• Best for confirmed battery life → FK Trading Huawei Mate 30. 9 hours in the buds and 48 hours total with the case is spelled out in the specs; the RSPK sheet doesn't quantify playtime.
• Best for call clarity → FK Trading Huawei Mate 30. Four microphones with environmental noise canceling is the only detailed mic setup between the two.
• Best for the newest Bluetooth spec → RSPK Open Ear Headphones. Bluetooth 5.4 vs 5.3 — a small gap, but it's the newer standard.
• Best for secure, locked-in fit during hard training → FK Trading Huawei Mate 30. Ear hooks plus three ear-tip sizes are designed to stop the buds working loose.
• Best for warranty confidence → RSPK Open Ear Headphones. A 2-year warranty is stated; the FK Trading sheet doesn't list one.
• Best for detailed, documented specs → FK Trading Huawei Mate 30. More of the important numbers — playtime, charging time, mic count, tip sizes — are actually published.
• Best for color preference → RSPK Open Ear Headphones if you want gunmetal rather than black.
In my opinion, the FK Trading Huawei Mate 30 is the stronger all-round pick for most people, because it tells you exactly what you're getting: 9 hours per charge, 48 hours total, a 1.5-hour USB-C recharge, a four-mic call setup, Bluetooth 5.3 and a fit designed to stay put. That's a complete, verifiable picture. I'd choose the RSPK Open Ear Headphones specifically if open-ear awareness is non-negotiable — cycling or road running where hearing your environment matters more than isolation — and the 2-year warranty is a genuine bonus there. Decide on fit style first; everything else follows.
Yes. Both the FK Trading Huawei Mate 30 and the RSPK Open Ear Headphones are rated IPX6, which covers sweat and rain during workouts. Neither listing claims full water immersion, so don't swim with either.
Only the FK Trading set publishes numbers: 9 hours of bud playback and up to 48 hours combined with the 500mAh case. RSPK describes "long playtime" but doesn't state a figure, so it's harder to compare directly.
The RSPK Open Ear Headphones are explicitly aimed at cycling, running and workouts, and their open-ear design keeps your surroundings audible. The FK Trading set is better suited to gym and indoor training where isolation is an advantage.
