• LORELEI B-C6 — biggest strength: A 50-hour built-in 500mAh battery plus a 3.5mm wired fallback, wrapped in a foldable over-ear frame that weighs just 205 g.
• LORELEI B-C6 — biggest trade-off: It's an over-ear headphone with sound isolation rather than active noise cancellation, so it blocks noise passively and is bulkier to carry than buds.
• PEFUPEW Earbuds — biggest strength: A sport-first design with flexible ear hooks, IP7 waterproofing and four ENC microphones for calls in loud places.
• PEFUPEW Earbuds — biggest trade-off: The 48-hour figure is total playtime with the charging case; each bud gives you up to 8 hours, so long sessions depend on topping up.
• Who each is for: LORELEI B-C6 suits travel, home office and long listening sessions; PEFUPEW Earbuds suit running, gym work and anyone who hates things shifting in their ears.
The LORELEI B-C6 is built around endurance. A 500mAh battery rated for 50 hours of playtime is the headline, and it means you can leave the charging cable at home on a long trip and still have music on the return leg. If the battery does run dry, the included 3.5mm braided cable lets you keep listening in wired mode — a genuinely useful backup that most wireless-only products don't offer.
The design is equally practical. At 205 g it's light for an over-ear headphone, the protein ear pads rotate inward at 100° and fold at 120°, and the multi-level adjustable headband lets you dial in the fit. Folded, it measures roughly 6.7 × 5.6 × 3.15, so it drops into a bag without eating the whole compartment. Dual 40mm dynamic drivers cover a 20 Hz – 20,000 Hz range, which is the standard full-range window you'd want for music and podcasts, and Bluetooth 5.3 with a built-in mic handles calls.
In my opinion, this is the pick for commuters, remote workers and students who want one pair for the desk, the plane and the couch. The touch controls and 10-metre Bluetooth range make it feel like a normal everyday headphone. Skip it if you want something that disappears into a pocket, need active noise cancellation rather than isolation, or plan to run and lift in your headphones — an over-ear frame with rotating cups is not the tool for that.
The PEFUPEW Earbuds take the opposite approach: small, secure and built to survive movement. The flexible ear hooks are the defining feature. They wrap around the ear rather than relying on a silicone tip alone, which is exactly the design that keeps buds in place during sprints, burpees or a sweaty gym session. IP7 waterproofing backs that up, so sweat and rain aren't a reason to take them off.
Sound is handled by a 14.2mm dynamic driver — noticeably larger than the typical earbud driver — paired with a three-layer composite diaphragm. Four ENC microphones are the other standout, and they're there to suppress background noise on calls, which matters if you take meetings from a street corner or a busy office. The brand claims 80% background-noise reduction; treat that as a design goal rather than a guarantee, but the four-mic array is a real hardware advantage over single-mic buds.
Battery is 48 hours total, with each bud rated at up to 8 hours at 50% volume and the case providing 4–5 additional charges. USB-C fast charging tops them up in about 1.5 hours, and the dual LED display on the case shows remaining power at a glance. Bluetooth range is 15 metres, and the low-latency design is aimed at people who don't want audio lagging behind video.
Skip it if you mostly listen at a desk for hours on end and want the bigger drivers and cushioned fit of an over-ear. These are for the active half of your life.
• Best for battery life → LORELEI B-C6. 50 hours of built-in playtime versus 48 hours total across buds and case.
• Best for workouts and running → PEFUPEW Earbuds. Ear hooks plus IP7 waterproofing are purpose-built for sweat and impact.
• Best for long-haul travel → LORELEI B-C6. Foldable, 205 g, and the 3.5mm cable means airplane entertainment systems still work.
• Best for calls in noisy places → PEFUPEW Earbuds. Four ENC microphones are designed to strip out background noise.
• Best for glasses wearers and people with sensitive ears → PEFUPEW Earbuds. Nothing presses on the top of your head or around your ears.
• Best for shared or multi-device use at home → LORELEI B-C6. Bluetooth 5.3, touch media controls and a 10-metre range suit a desk setup.
• Best for commuting in cold or wet weather → PEFUPEW Earbuds. IP7 waterproofing is the deciding spec.
• Most flexible for pure music listening → LORELEI B-C6. Dual 40mm drivers and a 20 Hz – 20,000 Hz range give it more acoustic headroom.
If I had to buy one, I'd take the LORELEI B-C6. The 50-hour battery, the 3.5mm wired backup and the foldable 205 g frame cover more of my actual day — desk work, travel and evening listening — than a pair of sport buds would. I'd recommend the PEFUPEW Earbuds instead if your priority is training: the ear hooks, IP7 rating and four-mic call setup are exactly what a runner needs and what an over-ear can't provide. Two different jobs, two different answers. Check the current price on Amazon before you commit, since value shifts over time.
FAQ
Keep the two devices within range — 10 metres for the LORELEI B-C6 and 15 metres for the PEFUPEW Earbuds — and confirm the pairing prompt on screen. If the connection drops, switch Bluetooth off and on again and re-select the device.
Disconnect from the first device before pairing with the second, since both products connect over standard Bluetooth rather than a multi-point setup described in their specs. The PEFUPEW Earbuds are listed as compatible with most Bluetooth devices, including phones, tablets and laptops.
The PEFUPEW Earbuds, clearly. Ear hooks, IP7 waterproofing and 8 hours per charge fit exercise far better than an over-ear headphone with rotating cups. The LORELEI B-C6 is the better choice for stationary listening and travel.
