If you want a wired, plug-and-play headset tuned for Nintendo Switch gaming with a boom mic you can flip out of the way, choose PDP Gaming LVL40; if you need a wireless over-ear Bluetooth headphone with up to 60 hours of playtime that doubles as a music and travel companion, choose JOMILIN B9.
These two get compared a lot because they sit in the same budget-conscious corner of the headphone market and both use 40mm drivers. But they are built for completely different jobs. One is a console accessory. The other is a general-purpose wireless headphone. Picking the wrong one for your setup is the fastest way to be disappointed, so let's break down what each actually does well.
• PDP Gaming LVL40 — biggest strength: Purpose-built for the Nintendo Switch family (Switch, Lite, OLED) with a 3.5mm wired connection, an on-ear volume dial, and a noise-canceling boom mic that flips up to mute.
• PDP Gaming LVL40 — biggest trade-off: It's wired only, so you're tethered to your controller or console, and it's on-ear rather than over-ear.
• JOMILIN B9 — biggest strength: Bluetooth 5.3 with up to 60 hours of playtime, dual-device pairing, and a folding over-ear design that works across iPad, tablet, PC, phone, and travel.
• JOMILIN B9 — biggest trade-off: It's a general-purpose Bluetooth headphone, not a gaming headset — no boom mic, and it relies on a built-in mic for calls.
• PDP Gaming LVL40 is for you if: You game on a Nintendo Switch and want zero setup, low latency, and a real gaming mic.
• JOMILIN B9 is for you if: You want one wireless headphone for music, calls, commuting, and casual gaming on multiple devices.
The LVL40 is a wired stereo gaming headset and it doesn't pretend to be anything else. The 40mm dynamic drivers cover a 20Hz–20,000Hz range with what PDP describes as strong bass and crisp highs — the kind of tuning that makes footsteps, explosions, and in-game audio cues land with some weight. Impedance sits at 40 ohm, which is friendly to the low-power headphone jacks on a Switch controller or handheld console.
The feature that matters most for gaming is the flexible noise-canceling boom mic. It's positioned close to your mouth, which means your teammates hear you clearly with less room noise bleeding in, and it flips up to mute instantly when you're not talking. There's also an on-ear volume dial so you can adjust levels without pausing or digging through menus — a small thing that becomes a big thing during a tense match.
Build-wise, it's deliberately light. The spec sheet lists it at just 0.1 kg, with an adjustable headband, noise-isolating ear cups, and breathable soft foam cushions. That's an on-ear design with round ear cups and a plastic/PU enclosure in the Mario red-and-blue colorway.
Buy it if you play on a Nintendo Switch, Lite, or OLED and want a headset that works the second you plug it into the 3.5mm jack — no pairing, no charging, no latency. Skip it if you need wireless freedom, want to listen on a phone or laptop over Bluetooth, or prefer the deeper seal of an over-ear cup.
The JOMILIN B9 flips the priorities. It's a wireless over-ear Bluetooth headphone built around Bluetooth 5.3, and the headline number is battery: up to 60 hours of playtime on a single charge, with a full recharge in about 2 hours. That's the kind of runtime that means you charge it on a weekend and forget about it for the rest of the week.
Bluetooth 5.3 also brings a genuinely useful trick — it can pair with two devices at once and switch between them. So you can be listening to a playlist on your phone and jump straight to a call on your laptop without re-pairing. Range is listed at 10 meters, which is comfortable for moving around a room or apartment.
The audio side uses 40mm drivers with a 20Hz–20,000Hz range and a bass-forward tuning aimed at rich low end with crisp mids. The ear cushions are a soft memory-protein material with breathable padding, and the headband is padded and adjustable via a slider, so long sessions are meant to stay fatigue-free. It's an over-ear fit, which generally means better passive isolation and a more enveloping sound than on-ear cups.
Two practical details stand out. First, it folds down for travel, so it stows small in a bag. Second, when the battery does run out, you can switch to wired mode through the 3.5mm jack and keep listening. Controls are touch-based on the ear cup for volume, calls, and music, and there's a built-in mic for hands-free calls.
Side-by-Side: Which Should You Choose?
• Best for Nintendo Switch gaming → PDP Gaming LVL40. It's explicitly built for Switch, Lite, and OLED with a 3.5mm wired connection.
• Best for battery life → JOMILIN B9. Up to 60 hours per charge with a 2-hour recharge is the clear win here.
• Best for voice chat and team comms → PDP Gaming LVL40. The flip-to-mute noise-canceling boom mic beats a built-in call mic for gaming.
• Best for travel and commuting → JOMILIN B9. Wireless, folding, over-ear, and it survives a long trip on one charge.
• Best for multi-device users → JOMILIN B9. Bluetooth 5.3 dual pairing lets you hop between phone and laptop.
• Best for zero-setup, no-latency plug-in → PDP Gaming LVL40. No pairing, no charging, works instantly through the headphone jack.
• Best for long-session comfort in an over-ear fit → JOMILIN B9. Padded headband, adjustable slider, and breathable over-ear cushions.
• Best for quick in-game volume tweaks → PDP Gaming LVL40. The on-ear volume dial is faster than touch controls mid-match.
In my opinion, this comes down to one question: are you buying a gaming headset or a wireless headphone? If you own a Nintendo Switch and want something that just works the moment you plug it in — with a real boom mic and instant volume control — I'd buy the PDP Gaming LVL40. It's the more focused tool for that one job.
But if you want a single headphone that handles music, calls, travel, and casual gaming across several devices, I'd buy the JOMILIN B9. The 60-hour battery, Bluetooth 5.3 dual pairing, folding over-ear design, and wired fallback make it the more versatile pick for everyday life. Most people who aren't dedicated Switch players will get more use out of the B9.
FAQ
No. The LVL40 is a wired headset that connects through a 3.5mm jack. It has no Bluetooth or battery, which is exactly why it works instantly with a Nintendo Switch and adds no latency.
Yes, over Bluetooth or through its 3.5mm wired mode. That said, it has no boom mic, so for in-game voice chat the PDP LVL40 is the better fit.
The JOMILIN B9, by a wide margin — it's rated for up to 60 hours of playtime with a 2-hour charge time. The PDP LVL40 has no battery at all because it's wired.
The JOMILIN B9 uses an over-ear fit with padded, breathable memory-protein cushions and an adjustable headband, which generally stays comfortable longer. The PDP LVL40 is lighter and on-ear, so it's comfortable in a different, more compact way. For price, check the current price on Amazon for whichever model you're leaning toward.
