How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a rugged, single-purpose pair of closed back studio headphones built for loud, mobile monitoring, choose Liquid Audio Sennheiser HD25; if you need a closed back studio headphone that comes as part of a complete USB recording bundle with a microphone, choose Audiosavings Se Electronics NEOM.
• Liquid Audio Sennheiser HD25 — biggest strength: Professional on-ear monitoring design with high noise attenuation, rotatable capsule for one-ear listening, and aluminum voice coils that handle very high sound pressure levels without distortion.
• Liquid Audio Sennheiser HD25 — biggest trade-off: It is strictly a wired headphone bundle (6.35 mm jack, detachable single-sided cable) with no microphone or interface included — you get monitoring only.
• Audiosavings Se Electronics NEOM — biggest strength: A two-item creator bundle pairing a 24-bit/192 kHz USB-C condenser microphone with a closed-back PRO-M50 headphone featuring 40 mm neodymium drivers and swiveling cups.
• Audiosavings Se Electronics NEOM — biggest trade-off: The headphone is 32 ohm with a coiled cable, and the set is heavier (3.7 lb) and USB-centric — it is not built for the same rugged field abuse the HD25 is designed for.
• Who the HD25 is for: DJs, ENG/camera operators, sound reinforcement engineers, and anyone who needs tough, isolating, single-ear monitoring in loud environments.
• Who the NEOM bundle is for: Podcasters, streamers, voiceover artists, and home musicians who want a mic and monitoring headphone together with plug-and-play USB-C.
The HD25 Plus is a closed-back on-ear monitor headphone, and its whole identity is durability under pressure. The design uses aluminum voice coils for high sensitivity, and the spec sheet explicitly calls out that it handles very high sound pressure levels without distortion. That matters in real rooms: a DJ booth, a live sound desk, a camera rig next to a loud stage. The 70 ohm impedance and 20 Hz–20,000 Hz frequency range are the kind of figures that suit being driven off a mixer or headphone amp rather than a delicate source.
The features that stand out to me are the practical ones. High attenuation of background noise means it blocks out a lot of what is happening around you. The rotatable capsule lets you flip one ear off for single-ear listening — essential for cueing a track or hearing the room while still monitoring. The cable is detachable and single-sided, which is a genuine repair-friendly choice for gear that lives in a bag. The bundle adds a Pig Hog PHX14-25 1/4" 25 ft headphone extension cable and a Liquid Audio polishing cloth, so you can reach across a studio or stage without hunting for an adapter.
Who should buy it? Someone who treats headphones as a tool, not a toy. If you are mixing on the move, working loud shows, or shooting in the field and need isolation plus one-ear flexibility, this fits. Who should skip it? Anyone who wants to record vocals, stream, or plug directly into a phone or laptop with no interface — there is no microphone here and the connection is 6.35 mm wired. It is also an on-ear design, so if you strongly prefer full circumaural cushioning for long mixing sessions, look elsewhere. Check the current price on Amazon before deciding, since bundles like this move around.
This is a different animal entirely — a two-item creator kit built around a USB microphone. The Se Electronics NEOM USB is a cardioid condenser with a 16 mm back-electret capsule, capturing 20 Hz–20 kHz and recording up to 24-bit resolution at 192 kHz sample rates, with supported rates from 44.1 to 192 kHz. It connects over integrated USB-C and works with Mac, Windows, iOS, and Android. That combination is aimed squarely at people who want to record or go live without an audio interface.
The control set is what makes it usable in practice: zero-latency headphone monitoring, onboard gain control, headphone level adjustment, and a dedicated mute button. For livestreaming, voiceover, or remote sessions, having mute and gain within arm's reach beats menu-diving. The mic itself is compact at 174 x 56 x 40 mm and weighs 445 g, so it sits easily on a desktop or travels in a bag.
The second half of the bundle is the PRO-M50 closed-back circumaural headphone. It uses 40 mm neodymium drivers with a wide 10 Hz–25 kHz response, 32 ohm impedance, and 97 +/- 3 dB sensitivity — easy to drive. It has swiveling ear cups, interchangeable suede and leather cushions, a stainless steel headband frame, and a detachable 100% OFC coiled cable with a gold-plated 3.5 mm plug plus a 1/4-inch adapter. A case and an extra ear pad are included too.
Side-by-Side: Which Should You Choose?

My Verdict
If I had to pick one, I would buy the Audiosavings Se Electronics NEOM bundle for most people starting out — in my opinion, getting a 24-bit/192 kHz USB-C condenser microphone and a capable closed-back PRO-M50 headphone in a single kit solves more problems for a podcaster, streamer, or home musician than a monitoring-only headphone does. That said, if your world is DJ booths, live sound, or camera work, I would take the Liquid Audio Sennheiser HD25 without hesitation: its isolation, one-ear capsule, and high-SPL tolerance are exactly what that job demands. Different tools, different jobs.
what are closed back studio headphones
Closed back studio headphones have sealed ear cups that block outside sound from getting in and keep your audio from leaking out. That isolation makes them useful for tracking, DJ work, and loud environments, and it is the design both the HD25 and the PRO-M50 use.
what are the best closed back studio headphones
There is no single answer, because "best" depends on the job. For loud, mobile, isolating monitoring the HD25's attenuation, one-ear capsule, and high-SPL handling fit; for desk recording with a mic, the PRO-M50's 40 mm drivers and swiveling circumaural cups in this bundle fit.
what is open back studio headphones
Open back studio headphones have vented ear cups that let air and sound pass through, which typically gives a wider, more natural sense of space but far less isolation and more leakage. Neither product here is open back — both are closed designs, so this is not the category you are shopping in.
what is closed back studio headphones
It is the same category as above: a headphone with sealed cups for isolation and minimal bleed. The HD25 is a closed on-ear monitor, and the NEOM bundle's PRO-M50 is a closed circumaural studio headphone with detachable coiled cable.
