• Amazon Renewed Beyerdynamic DT 770 — biggest strength: closed-back velour pads and a 5–35,000 Hz dynamic driver tuned for natural, balanced monitoring, backed by a spring steel headband where every part is replaceable.
• Amazon Renewed Beyerdynamic DT 770 — biggest trade-off: it is a renewed unit with a 90-day limited warranty, and the 32 Ohm version is wired-only with a fixed 1.6 m straight cable.
• Audio-Technica ATH-M30x — biggest strength: 40 mm drivers with rare earth magnets, a 15° swiveling circumaural design, and a collapsible frame that packs down small.
• Audio-Technica ATH-M30x — biggest trade-off: a 22,000 Hz ceiling and 47 Ohm impedance mean it is a mid-focused monitor, not a wide-bandwidth reference can.
• Pick the DT 770 if you monitor in one place for hours and want isolation plus repairability.
• Pick the ATH-M30x if you travel, fold, and need a light pair with a full 2-year manufacturer warranty.
The DT 770 is a closed dynamic headphone built for critical music and sound monitoring, and the spec sheet backs that up. The frequency range runs from 5 Hz to 35,000 Hz, which is wider than most monitors in this class, and the low-mass coil and diaphragm are described as producing transient performance you would otherwise associate with far pricier designs. The 32 Ohm version is optimized for phones, tablets, consoles, and laptops, so it does not demand an external amplifier. There are also 80 Ohm and 250 Ohm variants for studio and high-powered rigs, so impedance choice is a real decision, not a footnote.
Who should skip it? If you need something that folds flat and disappears into a backpack, this is not that headphone. It is renewed, so the 90-day limited warranty is far shorter than a new-unit warranty, and you should be comfortable with the idea of a refurbished pair. It is also wired, with no wireless mode at all. If any of those are dealbreakers, look at the other option.
Audio-Technica ATH-M30x: Who It's For
The ATH-M30x is the more portable, more forgiving monitor of the two. The 40 mm dynamic drivers use rare earth magnets and copper-clad aluminum wire voice coils, and Audio-Technica tuned them for enhanced detail with strong mid-range definition. That mid focus is exactly what you want for dialogue, voiceover, podcast editing, and AV post — the places where intelligibility beats sub-bass rumble. The circumaural design contours around the ears for isolation in loud environments with minimal bleed, which is the same job the DT 770 does, just in a lighter package.
Portability is the headline. The earcups swivel 15° and fold up to meet the headband, and the bundle includes a carrying pouch plus a headphone desk stand and microfiber cloth. The single-side cable exit keeps the cable out of your way, and the included 1/4" screw-on adapter widens compatibility. It ships with a limited 2-year manufacturer warranty, which is a meaningful advantage over a 90-day renewed warranty if peace of mind matters to you.
Where it gives ground: the frequency response tops out at 22,000 Hz, and sensitivity is listed at 96 dB with 47 Ohm impedance. That is a fine match for laptops and interfaces, but it is not a wide-bandwidth reference monitor, and the plastic enclosure is less rugged than a spring steel headband. If your work is deep bass analysis or decades-long durability, this is the compromise.
• Best for long studio sessions → Amazon Renewed Beyerdynamic DT 770. Velour pads, adjustable sliding earpieces, and a 5–35,000 Hz range suit hours of mixing.
• Best for travel and packing → Audio-Technica ATH-M30x. The 15° swiveling, collapsible earcups and included pouch make it the bag-friendly pick.
• Best for dialogue and mid-range work → Audio-Technica ATH-M30x. Its tuning targets enhanced detail and strong mid-range definition.
• Best for passive isolation in loud rooms → Amazon Renewed Beyerdynamic DT 770. The closed-back design and velour pads are explicitly built for noisy shared spaces.
• Best for repairability → Amazon Renewed Beyerdynamic DT 770. Every part is replaceable, and the spring steel headband is built to take abuse.
• Best warranty coverage → Audio-Technica ATH-M30x. Limited 2-year manufacturer warranty versus 90 days limited on the renewed DT 770.
• Best for low-impedance mobile gear → Amazon Renewed Beyerdynamic DT 770 (32 Ohm). It runs off phones, tablets, consoles, and laptops without an amp.
• Best for cycling and moving between locations → Audio-Technica ATH-M30x. Foldable, light, and bundled with a stand and pouch for grab-and-go monitoring.
If you are hunting for the best gaming headphones for cycling, neither of these is a wireless sweat-proof set — but if what you actually want is the best IPX7 waterproof headphones for cycling or the best sleep headphones for cycling, those are different product categories entirely. These two are wired studio monitors, and the right question is which one survives your workflow.
In my opinion, I would buy the Amazon Renewed Beyerdynamic DT 770 for studio monitor duty. The wider 5–35,000 Hz range, the closed-back velour isolation, the replaceable parts, and the spring steel headband all point to a headphone you keep for years and repair instead of replace. For cycling between sessions, I would still reach for the ATH-M30x because it folds and travels better — but for the desk, the DT 770 wins. Check the current price on Amazon before you commit, since renewed units move around.
what is studio monitor headphones
Studio monitor headphones are closed- or open-back wired headphones designed for accurate, balanced sound reproduction rather than boosted bass — used for mixing, editing, and critical listening. Both the DT 770 and ATH-M30x fit that definition, with dynamic drivers and passive sound isolation.
what are the best studio monitor headphones
There is no single best pair — it depends on your impedance needs and how you work. The DT 770 offers a 5–35,000 Hz range and replaceable parts; the ATH-M30x offers 40 mm drivers, a collapsible frame, and a 2-year warranty.
do i need studio monitors if i have headphones
Not necessarily. Monitor headphones like these give you isolation and portability that speakers cannot, which is why they are common for field recording, dialog editing, and late-night sessions. Monitors add room interaction; headphones remove it.
what are studio monitor headphones
Same answer as above, phrased plainly: they are wired over-ear headphones tuned for flat, detailed monitoring. The DT 770 uses velour pads and closed-back isolation; the ATH-M30x uses circumaural isolation with a mid-range focus.
