PSB Begins Shipping its M4U TWM Earbuds

full?d=1708789664.png

(February 24, 2024) Just a quick heads up for AV NIRVANA members: PSB Speakers has announced that its new M4U TWM earbuds are now available for purchase. This particular model has been in the works for nearly year, having been first announced at Axpona 2023. Priced at $199, PSB says the buds leverage "improved engineering and better componentry" to deliver a highly detailed sound. In addition, PSB's partnership with Audiodo Personal Sound allows owners to setup sound personalization options along with PSB’s proprietary RoomFeel technology. If you'd like to learn more, read PSB's official press release below; if you'd like to buy the M4U TWM and want to support AV NIRVANA, click here to purchase from Amazon.



From PSB:

The M4U TWM earbuds leverage powerful Magneto-Static technology in a Hybrid Planar dual driver design, utilizing the same technology found in high-end magneto loudspeakers and fitting them into remarkably compact earbuds. Dedicated transducers, one for high frequencies and one for low frequencies work together to make the in-ear listening experience truly pristine, reproducing sound with crisp highs, natural midrange and deep lush bass. Enhanced aptX™ Adaptive Bluetooth technology keeps everything in sync from movies to games with dynamic low latency and an adaptive bit rate supporting up to 24-bit high- definition audio quality.


With an IP65 rating the M4U TWM are sweatproof, water resistant and dustproof making them well-suited for active audiophiles to use in the gym, during cycling or running and even on a long commute. Convenient features like hard click buttons on both earphones make music control and voice calls hands-free and intuitive, while a smart USB-C charging case delivers a maximum of 32 hours of extended play time (8 hours out of the case and 3 additional charge cycles in the case).


Sound Optimization with Audiodo Personal Sound™

An integration with Audiodo Personal Sound™ technology is one of the most unique features offered in both wireless headphones. The breakthrough technology uses a non-replicable set of algorithms which allows listeners to calibrate their headphones in a way that accommodates for the listening qualities of their left and right ears independently. After completing a quick and easy hearing assessment accessed through the PSB Headphones app, Audiodo Personal Sound™ maps out a precise and thorough understanding of the listener’s hearing, calculates what changes need to be made based on personal sound perception, and formulates a compensation curve for the listener that can be applied to the overall headphone sound.

Natural RoomFeel™ Tuning
Created to deliver rich and natural sound through headphones, the next generation of PSB’s proprietary RoomFeel technology mimics the experience of listening to a pair of high-quality, full-range speakers properly set up in a good room. Carefully developed using research and expertise around ‘Room Gain’ – the energy and warmth that room boundaries add to the response curve of a flat-measuring loudspeaker, RoomFeel makes the music feel less ‘in the head’ by recreating an open and natural in-room listening experience through the M4U headphones.

PSB Headphones App

All headphone settings, including Audiodo Personal Sound™ tests and Transparency modes are accessed centrally through the PSB Headphones app, a full-featured app that allows users to adjust settings, check battery levels and regularly keep the headphones up-to-date with the latest firmware updates and codes.

Key Features of the M4U TWM

  • Wireless auto-pairing with any Bluetooth™ enabled device
  • Qualcomm aptX Adaptive Bluetooth™
  • Magneto-Static, Hybrid Planar dual driver design
  • Lightweight, secure fit suits any active lifestyle
  • Activate voice assistants or use hard click buttons for hands-free calling and music control
  • Rechargeable with 8 hours of playback and 24 hours in the smart charging case for 32 hours of total extended play time
  • IP65 rated for protection against sweat, dust and weather
  • RoomFeel™, Audiodo™ and cVc™ (clear voice capture) technologies built-in
  • 3 sizes of silicon tips for customizable fit

No, I haven’t tried these. You’re probably thinking of the Atlantic Technology TWS1. Which I think are fantastic

That's actually a relatively moderate price point. Not saying it isn't a chunk-a-change... but it could be worse!:rubeyes:

PSB 500s were the first speakers I ever purchased when I moved back to the US from the UK. A really wonderful company,
Agree. One thing about PSB: they have a track record of quality. Good science behind their products.
