Be driven by precision sound.

Experience exceptional portable audio with PSB's TWM True Wireless Micro Planar Earphones. These earbuds feature advanced Magneto-Static technology and a Hybrid Planar dual-driver design for studio-quality sound in a compact form. Enjoy up to 8 hours of battery life with the included smart charging case. With technologies like aptX™ Adaptive Bluetooth, Audiodo™, and RoomFeel™, you can enjoy a customized audiophile-grade listening experience.

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.

Post Traumatic Slave Syndrome
Format: Hardcover
Very well done book that does not make Black People feel angry nor White People guilty but from a gentle and skillful psychological point of view the book will "have you considered the impact of this or that upon both races as the result of Slavery in America?" A folk-like homespun way of tell these truths that masks the clinical questions that all trained psychologist asked..."and how would (does) that make you feel for all of us who ever sat on a couch?" The book made me consider the psychological impact of daily slave life with a WOW again and again as I never thought of the situations the book made me consider. The shared dehumanization of both whites and blacks due to the slave experience which goes a long way towards explaining to me why we as a country cannot truly discuss slavery's impact today. I found it self-healing and very necessary for all, both black and white, but especially for the victims of the African Holocaust my terminology not hers. I thought Dr. Leary PhD, did an excellent job and a high school or even a 6 grader could read the material without difficulty.

Healing & Understanding
Format: Paperback
We are living in a slave master's land (was the Indians..). Hundreds of years of slavery, mental torture and degradation and then "freed." No therapy. No understanding, not even patience. To listen to Dr DeGruy's youtube videos was so enlightening to me. Sorrow, but understanding and then JOY. I didn't understand the anger, towards myself or others. Now, I can see where so much pain has come from. I can show compassion and love towards myself and others. Whatever programming I had, has been deleted--destroyed. I look back with pride, hurt, and know that I, myself, can heal. What a blessing this woman has brought us! Thank you Dr. Joy DeGruy!
