If you want a lightweight, open-fit sports headphone from a well-known audio brand with ambient sound awareness, choose Sony WI-SP500; if you need long playtime, a secure hook design, and stronger water resistance, choose LEEMC Earbuds.
• Sony WI-SP500 — biggest strength: Open-type drivers that let ambient sound in, plus Bluetooth 4.2 with NFC pairing and a genuinely light build. Biggest trade-off: Just 8 hours of playback and only IPX4 splash resistance.
• LEEMC Earbuds — biggest strength: Up to 80 hours of total playtime, an IPX7 waterproof rating, ear hooks for a locked-in fit, and Bluetooth 5.4. Biggest trade-off: Passive noise cancellation only, and no NFC-style instant pairing.
• Who Sony WI-SP500 is for: Runners and gym-goers who want to hear traffic, training partners and gym announcements while they work out.
• Who LEEMC Earbuds is for: People doing long, sweaty sessions — marathon training, heavy cardio, outdoor work — who want maximum battery and serious water protection.
• Quick rule of thumb: Short, awareness-first workouts → Sony. Long, sweat-heavy, hook-it-and-forget-it sessions → LEEMC.
The Sony WI-SP500 is built around one clear idea: stay aware. Its open-type drivers are deliberately designed to let ambient sound in rather than seal it out. If you run on roads, share a gym floor, or cycle on mixed paths, that's a real safety feature, not a compromise. You hear the car behind you and the person calling your name, while still getting music. Sony pairs that with Bluetooth 4.2 and NFC, so tapping an NFC-capable phone to the headset handles the connection instead of menu-diving.
In the hand, this is a lightweight, plastic-bodied in-ear headphone with a rounded tip shape, a touch-based control method for media, and a carrying holder in the box alongside a Micro-USB cable and S/M ear tips. The plastic enclosure and plastic carrying case keep the package simple and portable — easy to toss in a bag pocket. Battery life is rated at up to 8 hours of playback, with an 8-hour charge time listed, and the whole thing carries an IPX4 rating: splash-proof and sweat-proof, which covers typical gym sweat and light rain.
Who should buy it: Anyone who treats awareness as part of their workout. Road runners, gym-goers who want to hear what's happening around them, and people who prefer a lighter, more open feel over an isolating seal. The NFC pairing is a nice touch if your phone supports it.
LEEMC Earbuds: Who It's For
The LEEMC Earbuds go the opposite direction: they're built to disappear into a long, hard session and keep going. The headline number is playtime — up to 80 hours, which is a completely different category from the Sony's 8. For anyone who charges their earbuds grudgingly and hates running out mid-week, that's the whole pitch. Bluetooth 5.4 is the newer wireless standard here, which typically means a more efficient, more stable connection than the older 4.2 in the Sony.
The design is sport-specific. Ear hooks are the standout physical feature — they loop over the ear to hold the bud in place, which matters most during running, jumping and anything high-impact. The buds are listed in an Ebony color with a sport style, and they use a dynamic driver. Controls are push-button rather than touch, which some people genuinely prefer: physical buttons are easier to operate with sweaty hands and less prone to accidental taps.
Water protection is the other big differentiator: IPX7 means the earbuds can handle full immersion for a limited time, well beyond splashes. Combined with passive noise cancellation, which blocks sound by physically sealing the ear canal rather than with electronics, this is a setup aimed at blocking the world out, not letting it in. There's also an LED display, which is handy for seeing charge status at a glance. Note there's no headphone jack — it's fully wireless.
Who should buy it: Long-session athletes and heavy sweaters. Marathon and half-marathon runners, cyclists, gym rats doing multiple weekly sessions, and anyone who works out outdoors in the rain. The hooks plus IPX7 plus 80 hours is a combination aimed squarely at people who don't want to think about their earbuds.
Who should skip it: If you need to hear your surroundings for safety, passive noise cancellation and a sealing fit work against you. And if instant tap-to-pair matters, the Sony's NFC gives it an edge there.
• Best for battery life → LEEMC Earbuds. Up to 80 hours vs. up to 8 hours on the Sony. Not close.
• Best for water and sweat resistance → LEEMC Earbuds. IPX7 (immersion-rated) beats IPX4 (splash-proof).
• Best for situational awareness → Sony WI-SP500. Open-type drivers let ambient sound in by design.
• Best for secure fit during high-impact movement → LEEMC Earbuds. The ear hooks are purpose-built to keep buds locked in.
• Best for quick, easy pairing → Sony WI-SP500. Bluetooth plus NFC means a tap can handle the connection.
• Best for newer wireless tech → LEEMC Earbuds. Bluetooth 5.4 is a newer generation than the Sony's 4.2.
• Best for lighter, more open listening → Sony WI-SP500. A lightweight, open-fit build with a rounded tip.
• Best for long training blocks away from a charger → LEEMC Earbuds. The 80-hour figure and LED display suit multi-day, multi-session use.
In my opinion, most people shopping this exact comparison are training hard and want their earbuds to keep up — so I'd buy the LEEMC Earbuds. The combination of up to 80 hours of playtime, IPX7 waterproofing, ear hooks for a secure fit, and Bluetooth 5.4 is simply more useful for everyday sport than 8 hours and IPX4.
I'd only flip to the Sony WI-SP500 if awareness is non-negotiable — road running, busy gym floors, or anywhere you need to hear what's around you. That open-type design is a real, deliberate feature, and for that specific job it's the better pick.
Not overall — it depends on your priority. The Sony wins on ambient awareness (open-type drivers) and NFC pairing. The LEEMC wins on battery life, water resistance, and fit security. For most hard-training athletes, the LEEMC specs are more useful.
The LEEMC Earbuds are listed at up to 80 hours of playtime, while the Sony WI-SP500 is rated at up to 8 hours. That's roughly a tenfold difference, which matters most for multi-day or multi-session training.
The LEEMC Earbuds carry an IPX7 rating, meaning they can handle immersion for a limited time. That's far beyond the Sony's IPX4 splash-proof rating. Still, IPX7 is a water-resistance rating, not a dedicated swimming certification, so treat it as strong sweat and rain protection rather than a swim guarantee.
Yes — arguably that's their best use case. The open-type drivers let ambient sound in, so you can hear traffic and your surroundings while you run. If outdoor safety awareness is your top priority, they're the stronger choice of the two. If you'd rather block the world out, go with the LEEMC Earbuds.
The LEEMC Earbuds. IPX7 water resistance plus ear hooks designed to stay put during heavy movement make them the better fit for sweaty, high-intensity sessions. The Sony's IPX4 covers light sweat and splashes but has less margin.
