• OYEALEX Active Noise Cancelling — biggest strength: Real active noise cancellation rated at -20dB, plus three listening modes (Bluetooth, TF card, FM radio, 3.5mm AUX) that make it unusually flexible for a single pair.
• OYEALEX Active Noise Cancelling — biggest trade-off: Around 20 hours of playback per charge and a 2-hour charge time, which is modest next to the competition here.
• MIDOLA Headphones — biggest strength: Up to 65–68 hours of playtime on a single charge, a lightweight foldable build, and 6 EQ modes to reshape the sound.
• MIDOLA Headphones — biggest trade-off: Noise control is passive sound isolation only — no active cancellation — so it won't silence a noisy room the way the OYEALEX pair will.
• Pick OYEALEX if you want quiet on demand and a 3.5mm wired option for laptop calls and movies.
• Pick MIDOLA if battery anxiety is your enemy and you want a light, packable over-ear for long days.
The OYEALEX EL-B4 is built around one idea: cut the noise. Its active noise cancellation is rated at -20dB, and the brand notes that the ANC also stretches battery life by reducing how hard the drivers have to work. Under the hood you get dual 40mm dynamic drivers covering 20Hz–20,000Hz with 20-ohm impedance, tuned for rich bass and a "cinema-level" surround feel. Bluetooth 5.0 with CSR chips handles the wireless side, with a 10-meter range and a built-in mic for hands-free calls.
Comfort is clearly a priority here. The memory-protein earmuffs (the brand says the material is German-made) are designed to spread pressure and reduce heat buildup, and the leather headband plus adjustable, foldable frame should suit longer sessions. There's a touch-and-button control mix for volume, and the whole thing weighs in at just 0.21 kg — genuinely light for an over-ear with ANC.
Who should buy it? Anyone who works near noise — open offices, shared apartments, flights — and wants to flip a switch and dull it. The 3.5mm AUX input is the sleeper feature: plug into a laptop headphone jack and you've got a zero-latency wired headset for laptop calls, editing, or gaming when Bluetooth lag would annoy you. It also takes a TF card and pulls in FM radio, which is rare and handy if you like offline listening.
MIDOLA Headphones: Who It's For
MIDOLA's B15 is the endurance play. The headline number is battery life — the title references 68 hours and the spec sheet lists 68 hours average life, with the feature copy citing up to 65 hours of playtime. Either way, that's roughly three times the OYEALEX figure. For someone who charges on Sunday and forgets about it until midweek, that changes the whole relationship with the product.
It's also the more modern wireless spec: Bluetooth 5.3 versus 5.0, a 33-foot range, and a stated audio latency of 16 milliseconds, which is a genuinely useful figure for anyone doing video calls or watching video where lip-sync matters. The 40mm dynamic drivers run at 32-ohm impedance with 105dB sensitivity and a 20Hz–20,000Hz range, and there are 6 EQ modes to switch between pop, rock, bass, vocals, podcasts, and video. That's a lot of on-the-fly tuning for a budget-minded over-ear.
The physical design leans portable and light: oval over-ear cups, a foldable frame, soft ear pads, and an adjustable headband. MIDOLA lists the weight at 7.04 ounces — noticeably heavier than the OYEALEX on paper, though "lightweight" is the brand's own framing, and foldability is what matters most when you're stuffing it in a backpack. The age range spans adult, teen, and kids, so it's pitched as a household-friendly pair.
The catch: noise control is sound isolation, not active cancellation. The enclosed cups will muffle some ambient sound, but a droning airplane cabin or a loud café won't be actively cancelled. If that's your priority, this isn't the pair. It does include a 3.5mm AUX jack and ships with an AUX cable, USB charging cable, and manual, so wired laptop use is still on the table.
• Best for noise cancellation → OYEALEX Active Noise Cancelling. It's the only one of the two with ANC, rated at -20dB.
• Best for battery life → MIDOLA Headphones. Up to 68 hours versus roughly 20 on the OYEALEX.
• Best for laptop and PC work → MIDOLA Headphones, narrowly. Bluetooth 5.3, a 33-foot range, and 16ms latency make it the more comfortable daily driver for meetings and video.
• Best for wired, zero-latency laptop audio → OYEALEX Active Noise Cancelling. The 3.5mm AUX input plus TF card and FM radio give it more input options.
• Lightest on the spec sheet → OYEALEX Active Noise Cancelling at 0.21 kg (about 7.4 oz), essentially a wash with MIDOLA's 7.04 oz — but OYEALEX pairs that weight with ANC.
• Best for sound customization → MIDOLA Headphones. Six EQ modes versus a single tuned signature on the OYEALEX.
• Best for travel and commuting → OYEALEX Active Noise Cancelling, because ANC is the feature that actually earns its keep on a plane or train.
• Best for a shared household → MIDOLA Headphones, given its adult/teen/kids age range and foldable, bag-friendly build.
If I were buying one of these for laptop-centric work, I'd take the OYEALEX Active Noise Cancelling. In my opinion, the combination of real ANC, a 3.5mm wired mode for lag-free calls, and a 0.21 kg over-ear frame is the more useful package for someone who splits time between a desk and a noisy room. The 20-hour battery is the price you pay, and it's a fair one if you charge nightly anyway. I'd only switch to MIDOLA if battery life is the single thing you refuse to compromise on — its 68 hours and Bluetooth 5.3 are genuinely compelling, and for pure wireless convenience it wins. Check the current price on Amazon for both before you commit, since value shifts over time. Either way, you're getting a lightweight wireless over ear headphone that can double as a headset for laptop duty.
FAQ
By the numbers, the OYEALEX Active Noise Cancelling is listed at 0.21 kg, while the MIDOLA Headphones come in at 7.04 ounces — roughly 0.2 kg. On paper they're close, but the OYEALEX delivers that weight alongside active noise cancellation, which is the more impressive feat.
Only the OYEALEX Active Noise Cancelling has active noise cancellation, rated at -20dB. The MIDOLA Headphones rely on passive sound isolation from their over-ear cups, which muffles some ambient noise but won't actively cancel a droning cabin or a loud room.
The MIDOLA Headphones, clearly — up to 68 hours of average battery life versus about 20 hours on the OYEALEX Active Noise Cancelling. If you'd rather charge once a week than nightly, MIDOLA is the practical pick. The OYEALEX charges in about 2 hours, so topping it up is quick but frequent.
