If you want a plug-and-play wired gaming headset with a flip-up boom mic and virtual surround sound, choose Amazon Renewed JBL Quantum 400; if you need an open-back studio headphone that doubles as a gaming headset via a detachable mic, choose Philips Over.
• Amazon Renewed JBL Quantum 400 — biggest strength: JBL Quantum Surround sound, a flip-up boom mic, and USB plus 3.5 mm connections that cover PC, Mac, Xbox, PS4 and Nintendo Switch out of the box.
• Amazon Renewed JBL Quantum 400 — biggest trade-off: It's a renewed unit with a 90-day limited warranty, and it's a closed, wired-only design, so there's no wireless freedom.
• Philips Over — biggest strength: Open-back 50 mm dynamic drivers tuned for detailed stereo sound, plus a detachable boom mic that turns music headphones into a gaming or work-from-home headset.
• Philips Over — biggest trade-off: Open-back headphones leak sound in and out, and it's wired-only with a touch-based control method rather than a dedicated game-audio platform.
• Pick the JBL if you want a ready-made gaming setup with surround processing and a mic that's always attached.
• Pick the Philips if you want one pair of headphones for music, monitoring, calls and gaming, and you don't mind open-back leakage.
The Quantum 400 is a closed-back, over-ear wired headset built around gaming first. The headline feature is JBL Quantum Surround, a virtual surround processing layer that's meant to give you a wider, more directional sense of a game's audio field. For anyone playing shooters or anything where footstep direction and environmental cues matter, that's the whole point of the headset. The 32 ohm impedance and 20 Hz – 20 kHz dynamic drivers are the kind of load almost any motherboard, controller or phone can drive without a separate amp.
The microphone is the other half of the story. It's a flip-up boom, which means you mute by physically raising it rather than hunting for a button — a small thing that turns out to matter a lot in the middle of a match. Connectivity is the practical part: a 3.5 mm jack plus a USB adapter, so the same headset moves between a PC, a Mac, an Xbox, a PS4 and a Nintendo Switch. If your setup is "whatever console or computer I'm on today," that flexibility is the reason to buy it.
Comfort is handled with memory foam ear cushions wrapped in soft PU leather, and the whole thing weighs 274 g. That's a reasonable figure for an over-ear gaming headset and it's the spec that matters most for marathon sessions. Round earcups, black finish, wired only.
Who should skip it? Two groups. First, anyone who wants wireless — there's no wireless technology here, it's strictly wired. Second, anyone uncomfortable with renewed hardware. This is an Amazon Renewed unit: it was inspected and tested by Amazon-qualified suppliers to work and look like new, and it carries a 90-day limited warranty with eligibility for replacement or refund under the Amazon Renewed Guarantee if you're not satisfied. That's a real safety net, but it's a shorter window than a new-product manufacturer warranty, and if that trade-off bothers you, this isn't your headset.
The Philips SHP9600MB is a different animal wearing a similar shape. It's an open-back, over-ear wired headphone with 50 mm dynamic drivers and a frequency range of 6 Hz – 35 kHz. That range is dramatically wider than the JBL's 20 Hz – 20 kHz, and paired with the open-back design it points at a very different listening philosophy: detail, air and stereo imaging rather than a closed, isolated gaming chamber.
Open-back is the key design decision. Because air flows through to the speaker element, pressure doesn't build up inside the cup, so what you hear stays clear and free of the echoey, boxed-in quality closed cups can develop. The trade-off is equally real: open-back headphones leak sound outward and let room noise in. In a quiet room with a decent mic, that's a huge win. On a noisy train or next to a loud air conditioner, it's a problem.
What makes it unusually flexible is the detachable boom mic. Attach it and the SHP9600MB becomes a proper gaming headset or a work-from-home business headset for calls; detach it and you have a pair of studio-monitor-style headphones for PC, DJ work, music, piano or guitar. That two-in-one behavior is the reason to buy it. The included 3.5 mm to 6.3 mm adapter means it connects to consumer gear and to pro audio interfaces alike.
Comfort and fit get more engineering than most: breathable ear-cup cushions aimed at long listening sessions, a comfort-fit shape that follows the ear's natural curve, and an adjustable headband with numbered sizes so you can dial in the fit and lock it. The enclosure is steel, which suggests a sturdier frame than plastic-heavy gaming headsets. Item weight is listed at 1.5 pounds.
Cabling is generous — roughly 5 feet with the mic attached and 9.8 feet without — so you can move around a desk or studio without yanking the cable. Controls are touch-based, and noise control is sound isolation.
Who should skip it? Anyone who needs isolation, anyone who wants wireless, and anyone who wants a single-purpose gaming headset where the mic never has to be found, attached or stored. If you game in a shared space or a loud room, the open-back design will fight you.
Side-by-Side: Which Should You Choose?
• Best for music, monitoring and studio use → Philips Over. The 50 mm drivers, 6 Hz – 35 kHz range and open-back tuning are aimed at critical listening, not game processing.
• Best for console hopping → Amazon Renewed JBL Quantum 400. USB plus 3.5 mm covers PC, Mac, Xbox, PS4 and Switch with one headset.
• Best for one headset that does gaming and work calls → Philips Over. The detachable boom mic swings between gaming headset and business headset.
• Best for a quieter, more natural soundstage → Philips Over. Open-back drivers let air flow and keep the sound clear without echoes.
• Best for closed, isolated listening → Amazon Renewed JBL Quantum 400. Sound isolation plus PU leather memory foam cushions keep your audio in and the room out.
• Best for a permanently attached mic → Amazon Renewed JBL Quantum 400. Flip-up boom means instant mute with no attaching or storing.
• Best for fit precision and long-session comfort → Philips Over. Numbered headband sizing and breathable cushions are built for long listening.
• Best for lower-risk ownership → Amazon Renewed JBL Quantum 400. The Amazon Renewed Guarantee and 90-day limited warranty give you a defined fallback.
• Best for cable reach on a big desk → Philips Over. Roughly 9.8 feet without the mic and about 5 feet with it.
In my opinion, most people searching this comparison should buy the Amazon Renewed JBL Quantum 400. It's the headset that does the job it advertises with zero fiddling: surround sound processing on board, a mic that's always there, and connections for every current platform. The Philips SHP9600MB is the better headphone — wider frequency range, open-back clarity, steel frame, smarter fit — and if you want one pair for music, monitoring, calls and gaming, I'd point you to it instead. But for pure gaming convenience in a shared or noisy room, the JBL wins. Check the current price on Amazon for each before you commit, since renewed and new stock move independently.
FAQ
Yes — it ships with a detachable boom mic, so you can attach it for gaming or work calls and remove it when you just want headphones. That's the core difference from the JBL, whose flip-up boom mic is permanently built in.
It's a wired 3.5 mm headphone with an included 3.5 mm to 6.3 mm adapter, so it connects to standard analog outputs. It doesn't have the JBL's USB adapter or console-specific surround processing, so treat it as a stereo gaming solution.
The Amazon Renewed JBL Quantum 400. It's closed-back with sound isolation via PU leather memory foam cushions, while the Philips is open-back and lets room noise in and your audio leak out.
