If you want a light, wired on-ear headset with a bass-forward tuning and an in-line mic for calls, choose MEGA Sony Extra Bass; if you need a comfortable over-ear wireless headset with a huge battery, a 40mm driver and a full accessory kit, choose Keenso Over Ear.
• MEGA Sony Extra Bass — biggest strength: a very light 120 g on-ear build with 30mm drivers, a wide 5 Hz–22 kHz frequency range and an in-line mic for hands-free calls.
• MEGA Sony Extra Bass — biggest trade-off: it's a wired-on-paper design with swivel earcups and a remote/app combo, so it depends on your phone and cable rather than a battery.
• Keenso Over Ear — biggest strength: Bluetooth 5.4 with up to 60 hours of playback, a 600 mAh battery, 40mm drivers and a bundle that includes two 3.5mm cables, a 6.35mm adapter, a 2-in-1 sound adapter and a USB power cable.
• Keenso Over Ear — biggest trade-off: it's the bulkier, more complex product, and the spec sheet leaves a few details (like the exact wired/wireless behavior) less clearly defined than the MEGA's.
• Who each pick is for: the MEGA for commuters and call-takers who want light and simple; the Keenso for long-session listeners, DJs and studio users who want wireless freedom and a big accessory kit.
The MEGA Sony Extra Bass (MDRZX110AP) is a wired on-ear headset built around one idea: bass. It uses 30mm dynamic drivers with a frequency response of 5 Hz to 22,000 Hz, and the design leans on an acoustic bass booster to push low-end response harder than a typical on-ear at this driver size. In practice that means a warm, thumpy presentation — good for hip-hop, electronic, pop and anything where the kick drum matters more than micro-detail. The in-line microphone handles hands-free phone calls, and the free smart key app lets you customize what the in-line remote does.
The physical design is where this one earns its place. At 120 g it's genuinely light, and the on-ear, swivel-style earcups fold flat for tossing in a bag. The enclosure mixes metal, plastic, rubber and silicone in black, and the 3.5mm jack means it works with basically anything that still has a headphone port — no pairing, no charging, no latency.
Who should buy it: commuters, students, office workers and anyone who takes a lot of calls and wants a grab-and-go headset that won't weigh on their head after an hour. Who should skip it: if you want wireless freedom, a long battery or isolation from a noisy train carriage, this isn't the tool — the design here is wired-first, and the noise-control field is listed as active noise cancellation, which is worth verifying against the model's actual behavior before you count on it for blocking out a plane cabin. If you need serious isolation or cable-free listening, look elsewhere.
The Keenso Over Ear is the more ambitious product on paper. It's a Bluetooth 5.4 headset that pairs in about one to three seconds after powering on, holds a connection out to roughly 10 meters (33 feet), and runs up to 60 hours of continuous playback on a full charge from its built-in 600 mAh lithium-ion battery. Those numbers describe a headset you charge once a week, not once a day — which is the whole point of this design.
Comfort is clearly the second pillar. The earcups use soft memory foam wrapped in protein leather, and the over-ear shape spreads pressure around the ear rather than pressing on it. The earcups rotate 90°, which lets you swing one aside to hear what's going on around you — the classic DJ move — and the adjustable headband is meant to fit a range of head shapes. The drivers are 40mm dynamic units covering 20 Hz to 20 kHz, so expect a fuller low end than a small on-ear can produce.
The package is unusually complete: two 3.5mm cables, a 6.35mm adapter (the big plug for mixers and amps), a 2-in-1 sound adapter and a USB power cable, with a Type-C charging port on the headset itself. There's also a memory card slot that accepts up to a 32GB microSD card (card not included), which is an unusual feature for headphones and points to standalone playback. Keenso backs it with a 90-day manufacturer warranty.
Side-by-Side: Which Should You Choose?
• Best for battery life and wireless freedom → Keenso Over Ear. Bluetooth 5.4, up to 60 hours of playback, ~10 m range and a 600 mAh battery.
• Best for all-day light comfort on a commute → MEGA Sony Extra Bass. 120 g, on-ear, swivel earcups that fold away.
• Best for phone calls → MEGA Sony Extra Bass. The in-line mic plus the smart key app for customizing the remote are built for exactly that.
• Best for studio, DJ and mixer work → Keenso Over Ear. The 6.35mm adapter, 90° rotating earcups and two 3.5mm cables are pro-gear accessories, not phone accessories.
• Best for bass-first listening → Both, but differently. The MEGA leans on an acoustic bass booster and 30mm drivers; the Keenso uses larger 40mm drivers with a 20 Hz–20 kHz range for deeper low-end weight.
• Best for plug-and-play with old devices → MEGA Sony Extra Bass. A 3.5mm wired jack works with anything, no pairing or charging.
• Best for a complete out-of-the-box kit → Keenso Over Ear. Two cables, two adapters and a charging cable are included.
• Best for the simplest possible ownership → MEGA Sony Extra Bass. Nothing to charge, nothing to pair, nothing to update.
In my opinion, the Keenso Over Ear is the one I'd buy — but only if you want wireless. Up to 60 hours of playback, Bluetooth 5.4, memory-foam over-ear comfort and a package that includes a 6.35mm adapter is a lot of capability in one box, and the 40mm drivers suit bass-heavy music and studio work better than a 30mm on-ear. I'd pick the MEGA Sony Extra Bass instead if you want the lightest possible wired headset for calls and commuting and don't want to think about charging anything. Check the current price on Amazon for both before you commit, since that's the factor most likely to swing a close call.
Both, in practice. It's a Bluetooth 5.4 headset, and the box includes two 3.5mm cables plus a 6.35mm adapter, so you can run it wired into a mixer or amp as well.
Yes. It has an in-line microphone for hands-free phone calling, and the free smart key app lets you customize the in-line remote's function.
The Keenso Over Ear, by a wide margin — it's rated for up to 60 hours of continuous playback from a 600 mAh battery. The MEGA Sony Extra Bass is a wired headset, so battery life isn't part of its design at all.
The Keenso Over Ear. The 90° rotating earcups, the 6.35mm adapter and the two included 3.5mm cables are aimed squarely at mixing and monitoring, while the MEGA is built for phones and everyday listening.
