If you want an open-ear clip design with app-based EQ, dual-device pairing and the stronger battery story, choose QCY C50; if you need maximum sweat and water protection, lighter buds and a punchier bass tuning, choose Baseus Bowie MC2.
• QCY C50 — biggest strength: 35 hours of total playtime, Bluetooth 6.0, app EQ customization and dual-device connection make it the more "connected" running companion.
• QCY C50 — biggest trade-off: IPX5 is fine for sweat and light rain, but it is not built for heavy downpours or getting fully soaked.
• Baseus Bowie MC2 — biggest strength: IP67 water and sweat resistance plus a 4.9g-per-bud build and CloudComfort air cushions make it the more rugged, featherweight option for sweaty sessions.
• Baseus Bowie MC2 — biggest trade-off: no app EQ and no active noise control — you get button control and a fixed tuning, so personalization is limited.
• Who each pick is for: QCY C50 for the runner who wants app tuning, two-device switching and the longest total battery; Baseus Bowie MC2 for the runner who sweats hard, runs in rain, or wears glasses and earrings and wants the lightest possible clip-on.
The QCY C50 is an open-ear clip-on sports earbud built around stability and control. The ear clips use soft silicone over flexible titanium memory alloy, and QCY describes an anti-drop ergonomic design meant to stay put during running, cycling and daily activity. The shell is finished in a white anti-fingerprint bionic leather texture, which sets it apart from the usual glossy plastic look. A 10.8mm dynamic driver covers a 20Hz–20,000Hz range, so the tuning is a fairly standard full-range setup rather than a bass-forward one.
What it does best is connection and stamina. Bluetooth 6.0 with 10m range handles pairing, and dual-device connection lets you keep a phone and a laptop or TV hooked up at once — useful if you take calls mid-run or move from treadmill to desk without re-pairing. Battery is the headline: 7.5 hours per charge and up to 35 hours total with the case, which is a genuinely long week of runs on one case charge. The QCY app adds EQ modes, button customization, battery readouts and firmware updates, and auto L/R correlation means you don't have to check which bud is which.
Baseus Bowie MC2: Who It's For
The Baseus Bowie MC2 is also an open-ear clip-on, but it leans harder into durability and lightweight comfort. Each bud weighs 4.9g and uses soft CloudComfort air cushions plus a slim wave C-ring and a 4-point ergonomic support structure — Baseus specifically calls out that the clip-on style won't interfere with glasses frames or earrings, which is a real consideration if you wear either while running. The 11mm custom dynamic driver with a titanium-coated diaphragm and AI SuperBass 2.0 tuning aims at a fuller low end than a plain open-ear, and the semi-transparent body reads more like a fashion accessory than gym gear.
The standout spec is IP67 water and sweat resistance, which puts it a clear step above splash-proof in wet conditions — rain and heavy sweat are in scope. Battery runs up to 40 hours total with SuperBass 2.0 on, and a 10-minute fast charge gives about 2 hours of playtime, handy when you've forgotten to charge before a run. Calls use a 4-mic AI matrix array with wind filtering, and Baseus Smart Connect handles switching between two devices over Bluetooth 6.0.
Buy it if you sweat heavily, run outdoors in the rain, or want the lightest, most glasses-friendly clip-on with the toughest water rating. Skip it if app-based EQ, touch gestures or noise control matter to you — the MC2 uses physical push buttons and has no app EQ or noise cancellation listed. The 2-year warranty is also the longer of the two.
Side-by-Side: Which Should You Choose?
• Best for water and sweat resistance → Baseus Bowie MC2 (IP67 vs IPX5).
• Best for app customization and EQ → QCY C50 (QCY app with EQ modes and button remapping; the MC2 has no app EQ).
• Best for glasses and earring wearers → Baseus Bowie MC2 (clip design explicitly avoids frames and ornaments; 4.9g per bud).
• Best for control preference → QCY C50 if you like touch, Baseus Bowie MC2 if you want physical buttons.
• Best for bass-forward sound → Baseus Bowie MC2 (11mm driver with SuperBass 2.0 vs a 10.8mm driver with no bass-boost feature listed).
• Best for fast top-ups → Baseus Bowie MC2 (10 minutes for about 2 hours of play; QCY lists a 7.5-hour charge time).
• Best for long-term peace of mind → Baseus Bowie MC2 (2-year warranty vs 1 year).
In my opinion, the Baseus Bowie MC2 is the better pure running earbud. IP67 is the difference-maker for anyone who actually sweats through their sessions or gets caught in rain, the 4.9g-per-bud build and glasses-friendly clip make it easier to forget you're wearing it, and the 11mm driver with SuperBass 2.0 should suit runners who want a fuller low end. The 10-minute fast charge is the kind of feature that saves a run when you forgot to plug in.
That said, I'd steer to the QCY C50 if app EQ, touch controls and dual-device switching matter more to you than ruggedness — its 35-hour total playtime and customization are real advantages. For most runners prioritizing durability and comfort, though, I'd buy the MC2.
how to run with earbuds
Pick a fit that stays put without clamping — open-ear clip designs like these two rest on the ear rather than sealing the canal, so you keep ambient sound for traffic awareness. Secure the clip over the ear, check the C-ring or ear clip sits flat, and test with a short jog before a long run. Both are designed for stability during running, cycling and workouts.
how to connect jbl running earbuds
This is brand-specific, so the steps differ from QCY or Baseus. In general, open the case, put the buds in pairing mode, then select the device in your phone's Bluetooth list. For the two earbuds here, both use Bluetooth 6.0 with a 10m range and support dual-device connection.

Again, that's a different brand with its own app and pairing routine. The principle is the same: enable Bluetooth, hold the buds in pairing mode until the light flashes, then connect from your phone. With the QCY C50 and Baseus Bowie MC2, pairing is handled over Bluetooth 6.0 and both can stay linked to two devices.
how to run with wired earbuds
Route the cable under your shirt or behind your neck so it doesn't snag on arms, and use a clip to fix the slack. Neither the QCY C50 nor the Baseus Bowie MC2 has a headphone jack — both are fully wireless, so cable management isn't a concern here.
