PSB M4U 8 Wireless Noise Cancelling Headphone Review & Overview
The PSB M4U 8 is a wireless over-ear headphone that integrates active noise cancellation (ANC) with PSB’s legacy of high-fidelity sound. The main purpose of this product is to deliver a reference-quality audio experience in a convenient, wireless format, making top-tier sound accessible for commuting, travel, and critical listening at home. It is designed for a specific target audience: the discerning listener or aspiring audiophile who values accurate sound reproduction above a long list of smart features. This is for someone who can hear the difference between a good headphone and a great one.
Key specifications include support for high-quality Bluetooth codecs like aptX, a battery life of around 18 hours with ANC activated, and the ability to function in multiple modes: passive (power off), active wired (power on, using internal DAC and amp), and active wireless. The inclusion of a built-in amplifier ensures that the drivers receive optimal power regardless of the source device. In my experience, the attention to these acoustic fundamentals is what truly sets the M4U 8 apart from more mainstream brands, making it a tool for enjoying music rather than just a gadget for blocking noise.

Key Features & Performance
The PSB M4U 8’s feature set is thoughtfully curated to support its primary goal: unparalleled sound. Rather than packing in gimmicks, it focuses on getting the core audio experience right.
Reference-Quality Sound Signature
The heart of the M4U 8 is its sound profile. PSB utilizes its Room Feel technology, which is based on extensive research into how humans perceive sound in a room. The result is a frequency response that feels remarkably natural and balanced. The bass is present and articulate but never overpowers the mids, which are clear and forward, allowing vocals and instruments to shine. The treble is detailed without being harsh or sibilant. Compared to popular models from Bose or Sony, which often have a more consumer-friendly V-shaped sound, the M4U 8 offers a flatter, more accurate response that is less fatiguing over long periods and more faithful to the original recording.
Adaptive Noise Cancellation with Active Listen
The noise cancellation system is effective at reducing low-frequency rumbles like airplane engines and air conditioners. However, its most distinctive feature is the two ANC modes: Noise Cancelling and Room Feel. The Noise Cancelling mode provides strong isolation, while Room Feel intentionally allows some ambient sound to seep in, creating a more open and natural listening environment, similar to being in a quiet room. Furthermore, the Active Listen mode uses the external microphones to amplify surrounding sounds, which is perfect for having a conversation or being aware of airport announcements without taking the headphones off. This flexibility is incredibly useful in real-world scenarios.
Built-in High-Performance Amplifier and DAC
A significant differentiator is the integrated amplifier. When you use the headphones in “Active” mode, even with a wired connection, you are bypassing your device’s internal sound card and using the M4U 8’s own digital-to-analog converter (DAC) and amplifier. In my testing, this made a noticeable difference, especially with high-resolution audio files. The sound was fuller, more dynamic, and had a blacker background. This feature essentially future-proofs your headphones, ensuring they can reveal the full potential of better source material as you upgrade your gear.
Build, Comfort, and Battery Life
The build quality is robust, with a mix of metal and high-quality plastics that feel durable without being excessively heavy. The earcups are generously sized and plush, creating a good seal around the ears essential for both bass response and noise cancellation. I found them comfortable for multi-hour listening sessions. The 18-hour battery life is solid, though it falls short of some class leaders that now offer 30+ hours. It is, however, perfectly adequate for a full day of travel or a week of commutes.

Final Verdict
The PSB M4U 8 is a specialist tool that excels at its primary job: delivering exceptional sound. It makes a compelling case for itself in a market often dominated by marketing and feature-checklists. For the right user, its performance is well worth the trade-offs.
Pros
- The audio fidelity is simply outstanding, offering a balanced and natural sound that rivals wired audiophile headphones.
- The versatile noise cancellation with Room Feel and Active Listen modes provides a more nuanced and practical experience than simple on/off ANC.
- The built-in amp and DAC ensure optimal performance from any source, a feature rarely found in wireless headphones.
- Construction is solid and the plush earpads ensure long-term comfort.
Cons
- The included hard case is very large and bulky, making it less than ideal for stuffing into a packed bag.
- It lacks some modern conveniences like automatic play/pause when you remove the headphones.
- Those seeking a heavy, bass-forward sound for EDM or hip-hop might find the balanced signature too neutral.
I highly recommend the PSB M4U 8 for music lovers, audiophiles, and anyone who considers sound quality the non-negotiable feature in a headphone. You should buy these if you want the most accurate and engaging sound possible from a wireless, noise-cancelling model. However, you might want to look at other options if extreme portability, the longest possible battery life, or hands-free smart features are your absolute top priorities.
