Superior Sound, Perfected for You
The TWM utilizes powerful Magneto-Static technology in a Hybrid Planar dual driver design for clear, detailed sound. A high-frequency Magneto-Static driver offers crisp, high-resolution sound even at low volumes, while the dynamic planar midrange/bass driver delivers deep bass and natural midrange. Custom hearing tests with Audiodo Personal Sound™ via the PSB Headphones App ensure precise sound balance, with Volume Dependent Compensation and four EQ presets for tailored listening experiences.
Signature RoomFeel™ Tuning
PSB's RoomFeel™ technology emulates the experience of listening to high-quality speakers in a well-designed room, creating a natural sound. This technology incorporates research on 'Room Gain,' which accounts for the warmth and energy that room boundaries add to a speaker's response curve. RoomFeel minimizes the 'in your head' sensation, offering an open, in-room listening experience with the M4U TWM, ensuring a non-fatiguing and natural sound whether you're on the go or at the gym.
Active and Adaptive
The M4U TWM headphones adapt to your surroundings as you go about your activities. These headphones offer seamless pairing with aptX™ Adaptive Bluetooth, ensuring high-quality sound with low latency for gaming and movie watching. Whether you're at home or on a call outdoors, cVc™ (clear voice capture) technology minimizes background noise, ensuring clear voice quality in any environment.
Portable and easy extended listening
These earbuds feature convenient click buttons for volume control, track skipping, and calls. The smart charging case offers wired USB-C and wireless charging options, providing 8 hours of playback and 24 hours of backup power. Included are three sizes of silicon tips for noise isolation and secure fit. With an IP65 rating, they are sweatproof, water-resistant, and dustproof, perfect for active lifestyles. The PSB Headphones App enhances control with sound settings, Audiodo profiles, noise transparency levels, EQ presets, and battery monitoring.
I was quite excited to try these earphones due to the promise of “room feel” and audiodo profile to get the best sound possible. These units delivered on the sound front, the bass extension is very good with plenty of dynamic punch and the details are all there. The best sounding IEM’s I have tried. My problem with these started with me being able to get a good fit. Only one size of ear tips was supplied and that was too big, so if I was exercising or riding my bike they would come loose and fly out after a few minutes. On top of that, I have had problems with connectivity the whole time. One or both disconnects and tries to reconnect constantly (with all the associated crackling) if I am on the move at all, even while walking. They even say I am “out of range” when I am holding the phone two feet away. As a result, I cannot use these to listen during a casual walk to the point where I just want to throw them away. Very frustrating, doubly so when they sound so great. Note that I have no problems with connecting to my Apple AirPods and Focal Bathys headphones so I don’t believe it is an issue with my phone.
