We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a full room-filling monitoring setup you can also use for gaming, casual listening and the occasional party, choose Mackie CR3.5; if you need a closed-back headphone you can wear anywhere and track quietly without disturbing anyone, choose Audio-Technica ATH-M20x.
• Mackie CR3.5 — biggest strength: a powered stereo monitor pair with a 3.5" woven woofer and 1" silk dome tweeter, 50 watts of output, and a tone knob plus location switch that lets one set of speakers move between studio reference and casual listening.
• Mackie CR3.5 — biggest trade-off: it's corded, tabletop-mounted, and open to the room. Everyone around you hears what you hear, and there's no isolation at all.
• Audio-Technica ATH-M20x — biggest strength: 40mm dynamic drivers with rare earth magnets and copper-clad aluminum voice coils, covering 15 Hz to 20 kHz in a closed-back over-ear design that isolates external noise and keeps your mix from bleeding out.
• Audio-Technica ATH-M20x — biggest trade-off: it's a single wired headphone, not a speaker system. It gives you one private listening position, no stereo room image, and no way to play audio out loud.
• Who the Mackie CR3.5 is for: desktop producers, gamers and casual listeners who want speakers on the desk that can be tuned from flat to fun.
• Who the ATH-M20x is for: musicians, podcasters and creators who need private, noise-isolating monitoring on a tight budget and want portability.
Think of the CR3.5 as a small active speaker system that happens to be voiced for studio work. Each speaker runs a 3.5" woven woofer crossed to a 1" silk dome tweeter, with 50 watts of maximum output power driving two channels. That combination is what gives it clean, articulate mids and highs — the kind of sound you want when you're checking whether a vocal sits right or a kick drum is too loud. Because it's a stereo pair, you get an actual left-right image in front of you, which is something no single headphone can replicate in the same way.
The interesting part is the tone knob. Mackie starts you at a transparent, flat response — the reference setting — and lets you dial in bass and high-end sparkle as you turn it. So the same speakers that let you mix critically can be pushed into a warmer, punchier sound for gaming or just hanging out. There's also a location switch: desktop mode is tuned for close-up listening at the desk, bookshelf mode for listening from across the room. That's a genuinely useful feature if your setup lives in a bedroom or a shared living space and you don't always sit two feet from the speakers.
Connectivity is broad. TRS and RCA inputs take audio interfaces, mixers and turntables; a 3.5mm input handles PCs, laptops, phones, tablets, projectors and TVs. There's a built-in headphone output too, so plugging in headphones mutes the speakers and switches you to private listening without unplugging anything. The box even includes the cables you need, plus foam isolation pads to decouple the speakers from your desk. It's corded, tabletop-mounted, and weighs about 10.2 pounds.
Audio-Technica ATH-M20x: Who It's For
The ATH-M20x is the classic entry point into proper studio monitoring on headphones. Its 40mm dynamic drivers use rare earth magnets and copper-clad aluminum voice coils, and the rated frequency range runs from 15 Hz to 20 kHz. In practice that means you hear deep low end and crisp highs with enough detail to catch small problems in a recording. Audio-Technica tunes these with an emphasis on bass, so kick drums and basslines come through with punch rather than thinning out — handy for home recording, beatmaking and content creation where you need to feel the low end, not just hear it.
The design is where it earns its place in a studio. It's over-ear and closed-back, which means the earcups contour around your ears and physically block outside noise while also keeping your audio from leaking into a live microphone. If you record vocals or a podcast in a room with a fan, a computer, or traffic outside, that isolation is the difference between usable takes and constant retakes. The 15° swiveling earcups help the fit sit properly for long sessions, and the build mixes plastic, fabric and memory foam cushioning — light enough at 6.56 ounces that it won't fatigue your neck.
Cabling is single-sided and 9.8 feet long, exiting the left earcup so it stays out of your way and you always know which side is which. It terminates in a 3.5mm plug with a 1/4" snap-on adapter, so it works on a phone or laptop as easily as on an interface or mixer. This particular listing also bundles extras: a headphone case, a stand, a microfiber cleaning cloth and a bottle of headphone cleaner.
Buy the ATH-M20x if you need private, isolated monitoring, you record with microphones, or you want something you can carry. Skip it if you want to fill a room with sound, need speakers for gaming or casual listening out loud, or prefer wireless — this is a strictly wired, single-listener tool.
Side-by-Side: Which Should You Choose?
• Best for mixing out loud in a room → Mackie CR3.5. A true stereo pair with a flat starting point and a 1" silk dome tweeter.
• Best for recording with a microphone → Audio-Technica ATH-M20x. Closed-back cups reduce bleed into the mic.
• Best for gaming, movies and casual listening → Mackie CR3.5. The tone knob and location switch let you shift from reference to fun.
• Best input flexibility → Mackie CR3.5. TRS, RCA and 3.5mm inputs cover interfaces, mixers, computers, consoles and TVs.
• Best for portability → Audio-Technica ATH-M20x. 6.56 ounces, a single 9.8-foot cable and a carry case in the bundle.
• Best for long sessions → Audio-Technica ATH-M20x. Lightweight over-ear fit with memory foam cushioning and swiveling cups.
• Best for a one-and-done desk setup → Mackie CR3.5. Speakers, cables, isolation pads and a headphone out in one box.
In my opinion, the ATH-M20x is the smarter first purchase for most people starting out, because a closed-back headphone solves the two problems beginners hit hardest: noise coming in and sound leaking out. It also travels. But if your work happens at a desk and you want the option to listen out loud — to mix, game or just enjoy music — I'd take the Mackie CR3.5, since its tone knob and location switch cover far more ground than a single fixed tuning. If you can only buy one and you have a quiet room to yourself, go Mackie. If your room is shared, noisy, or you record vocals, go Audio-Technica.
what is studio monitor headphones
Studio monitor headphones are headphones built for accurate, detail-focused listening rather than a boosted, consumer-friendly sound. The ATH-M20x fits that description with 40mm dynamic drivers, rare earth magnets and a 15 Hz to 20 kHz range in a closed-back, over-ear design meant for checking mixes.
what are the best studio monitor headphones
There's no single winner, because "best" depends on your room and your work. The ATH-M20x is a strong pick if you need isolation and portability, while a speaker-based monitor like the Mackie CR3.5 suits anyone who wants to hear a stereo image in the room instead of on their head.
do i need studio monitors if i have headphones
Not necessarily — headphones and speakers answer different questions. The ATH-M20x isolates you and travels, but it can't show you how a mix translates in a room; the Mackie CR3.5 plays out loud with a stereo image and a switchable desktop/bookshelf tuning, which headphones can't replicate.
what are studio monitor headphones
They're headphones tuned for monitoring: revealing detail, controlled bass, and a closed or open design chosen for the job. The ATH-M20x leans toward enhanced bass with a wide 15 Hz–20 kHz bandwidth, so it works for tracking and casual content creation without losing low-end punch.
