If you want immersive, high-fidelity detail with deep bass for critical mixing and stage monitoring, choose BASN Metalen 4; if you need reliable, all-day comfort and a straightforward closed-back design for studio isolation, choose Audio-Technica ATH-M20x.
• BASN Metalen 4: Delivers exceptional sonic detail with its hybrid 4-driver setup (2 balanced armature + 2 dynamic) but requires proper ear tip fitting to achieve the promised isolation.
• Audio-Technica ATH-M20x: Offers robust build quality and passive noise cancellation in a lightweight over-ear form factor, though it lacks the ultra-high frequency extension of in-ear monitors.
• Who is this for? The BASN is built for musicians who prioritize soundstage depth and bass impact on stage or in the booth, while the Audio-Technica suits those needing long-duration wearability and standard studio monitoring.
The BASN Metalen 4 is engineered for the musician who demands absolute precision in their audio signal. This isn't just another pair of earbuds; it is a professional in-ear monitor system featuring four distinct drivers per side. By combining two dynamic drivers with two balanced armature drivers, the design aims to separate the frequency spectrum effectively. The dynamic drivers handle the low-end frequencies, delivering what the specifications describe as "heavy, impressive driven bass" with fast attack and decay. Meanwhile, the balanced armature components take care of the mids and highs, ensuring that every vocal nuance and instrument detail remains clear and articulate.
For a drummer, bassist, or singer, the ability to hear exactly what is happening in the mix without external interference is non-negotiable. The Metalen 4 addresses this through its physical design. The enclosure is crafted from CNC-milled metal with a matte gray finish, giving it a durable, industrial look suitable for the rigors of live performance. The inclusion of a 1/4-inch adapter means these can plug directly into many professional audio interfaces or stage boxes without needing extra dongles. Furthermore, the cable management is thoughtful; you get two detachable MMCX cables. One is silver-plated OFC for a brighter, more detailed sound signature, while the other features an inline microphone, allowing you to switch between pure listening and communication modes instantly.

However, this level of technical complexity comes with specific requirements. Because these are in-ear monitors, they rely entirely on a perfect seal to function correctly. The kit includes multiple sizes of silicone tips and memory foam options, which suggests that finding the right fit is part of the experience. If you struggle with ear canal shapes or prefer not to have anything inside your ear during long sessions, this might not be the path for you. But if you are looking for headphones for music production where the smallest detail matters, and you need a device that offers a wide soundstage and low distortion, the Metalen 4 stands out as a serious tool rather than a casual accessory.
The Audio-Technica ATH-M20x represents the classic approach to professional monitoring: large drivers, over-ear cups, and simple reliability. These headphones utilize 40mm neodymium drivers to cover a broad frequency range from 15 Hz to 20,000 Hz. While the bandwidth is slightly narrower on the extreme ends compared to some audiophile gear, it covers the entire critical spectrum needed for mixing and DJing. The closed-back design is the star here, providing excellent passive noise cancellation. This means no batteries are required to block out the hum of an air conditioner or the chatter of a room; the physical construction of the ear cups does the work.
Comfort is a major selling point for the M-Series line, and the M20x continues that tradition. Weighing in at just 6.7 ounces (approximately 190 grams), these are among the lighter professional headphones available. The over-ear shape wraps around the ears rather than pressing against them, which reduces fatigue during marathon mixing sessions. For someone who spends hours tweaking EQ curves or editing vocals, this weight distribution makes a tangible difference. The build itself feels sturdy, utilizing copper-clad aluminum wire voice coils to ensure durability and consistent electrical conductivity over time.
What sets this model apart for the beginner or the practical producer is its versatility and ease of use. The cable is a straight, left-side exit design that measures nearly 10 feet (3 meters), giving you plenty of room to move around your studio desk. The bundle also includes a desktop stand, which speaks to the workflow of keeping your equipment accessible and organized. Unlike the in-ear monitors, there is no need to worry about fit or seal issues. You simply put them on, and the isolation happens automatically. If you are searching for the best headband headphones for music production that offer a balance of affordability and professional-grade performance, the M20x delivers a straightforward, no-nonsense solution that prioritizes long-term wearability and consistent sound reproduction.
• Best for bass response and low-end impact → BASN Metalen 4 (Dual dynamic drivers provide deeper, warmer lows).
• Best for extended wearing comfort → Audio-Technica ATH-M20x (Lightweight over-ear design prevents ear fatigue).
• Best for portability and stage use → BASN Metalen 4 (In-ear form factor allows for total freedom of movement).
• Best for studio isolation without power → Audio-Technica ATH-M20x (Closed-back cups block ambient noise passively).
• Best for detail retrieval in complex mixes → BASN Metalen 4 (Hybrid driver architecture separates frequencies sharply).
• Best for beginners on a budget → Audio-Technica ATH-M20x (Includes a stand and offers a complete, ready-to-use package).
• Best for cable flexibility → BASN Metalen 4 (Two distinct cable options: one for detail, one with mic).
• Best for general-purpose listening → Audio-Technica ATH-M20x (Standard 3.5mm and 6.35mm jack compatibility fits most setups).
After analyzing the technical specifications and intended use cases for both devices, I would personally choose the BASN Metalen 4 if my primary goal was critical music production where detail and bass accuracy are paramount. The hybrid driver configuration offers a level of sonic separation that over-ear dynamic drivers simply cannot match in this price bracket, making it superior for identifying subtle flaws in a mix. However, if my priority shifts toward comfort and long-duration studio sessions where I need to forget I am wearing headphones, the Audio-Technica ATH-M20x becomes the logical choice. In my opinion, for dedicated in ear headphones for music production, the Metalen 4 provides a more specialized and technically advanced experience, whereas the M20x remains the gold standard for reliable, comfortable over-ear monitoring. Both are capable tools, but the BASN wins on raw audio engineering, while Audio-Technica wins on ergonomics.
These are strictly wired in-ear monitors that connect via a standard 3.5mm jack, requiring no batteries or Bluetooth pairing.
While the product listing highlights a desktop stand and dual-jack compatibility, the included accessories focus on the headphones themselves and the stand rather than spare cables or ear pads.
The Audio-Technica ATH-M20x uses a closed-back design to block external noise physically, while the BASN Metalen 4 relies on the seal created by the ear tips to isolate sound internally.
Yes, the included 1/4-inch adapter allows you to plug the 3.5mm output directly into standard instrument amplifiers or audio interfaces.
