COMING SOON

  • aptX™ Adaptive HD Bluetooth connectivity
  • Custom sound calibration with Audiodo™
  • Natural and open RoomFeel™ tuning
  • Leverages Magneto-Static technology

Superior Sound, Perfected for You

The TWM leverages powerful Magneto-Static technology in a Hybrid Planar dual driver design which reproduces sound with minimal distortion, crisp highs, natural midrange and deep, lush bass. Dedicated transducers, one for high frequencies and one for low frequencies work together to make the whole mix sound truly pristine. The high frequency Magneto-Static driver utilizes a thin, low mass diaphragm driven in a static magnetic field to move the diaphragm at ultra-high speeds with minimal distortion for crisp, clear, ultra-high resolution sound reproduction, even at low volume levels. The dynamic planar midrange/bass driver combines deep, fast bass and rich, natural midrange with a wide soundstage. The result of this Hybrid Planar design is destined to be pure music to your ears.

While most earbuds assume that your hearing is consistent on both ears, the reality is the opposite – no two ears hear in the same way. Accessed through the PSB Headphones App, a custom hearing test by Audiodo Personal Sound™ analyzes your left and right ear separately and maps out a precise understanding of your unique hearing. The latest implementation of Audiodo includes a Volume Dependent Compensation feature so the TWM can accurately match the timbral balance of the music at any volume level you choose. In addition, there are four EQ presets you can engage for specific music or movies – tighter bass, more detail, better dialogue and the default preset – RoomFeel™.

Signature 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 your head’ by recreating an open and in-room listening experience through the M4U TWM. Whether you’re moving through a busy street, catching transportation or at the gym, RoomFeel brings you the most non-fatiguing and natural sound possible.

Active and Adaptive

Using adaptive technologies, the M4U TWM headphones adjust to your environment while you move, work and play. Pair the headphones to your device seamlessly with aptX™ Adaptive Bluetooth, a 24-bit, HD universal Bluetooth technology that uses a variable bitrate to enable low-latency audio reproduction for playing games or watching movies while still offering the best possible sound quality. Whether you’re at home or outside while taking a voice call, cVc™ (clear voice capture) technology suppresses any background or ambient noise around you, so you still transmit crystal-clear voice quality no matter what environment you’re in.

Easy, Extended Listening

Hard click buttons on both earphones make volume control, skipping tracks, and voice calls easy and intuitive. The smart charging case with auto-pairing offers both wired USB-C and wireless charging options. Enjoy 8 hours of playback time and an additional 24 hours of charge stored in its accompanying case.

Included with the earphones are 3 sizes of comfortable silicon tips to provide excellent noise isolation and an in-ear fit that stays put, even if you’re moving. The earbuds are IP65 rated, making them sweatproof, water resistant, dustproof and well-suited for any active endeavor be it the gym, cycling, running or a long commute.

The full featured PSB Headphones App turns your device into a remote control for your M4U TWMs, giving you access to specific sound settings and features that you can adjust for a richer listening experience. With the tap of a few buttons you can create a sound profile using Audiodo, control noise transparency levels, choose from preset EQ settings, check battery level and more.

GREAT 80v edger (but Kobalt users beware)
Size: 8" Edger Gen1, Size: 8" Edger Gen1
This Greenworks 80v edger is fantastic. I was surprised at how sturdy and rigid the shaft is - much more so than the very much more expensive Stihl Brushcutter I used for years. I like the adjustability of the blade depth and the power is impressive. You will get more run time with higher amp batteries - I have both 2.0 and 2.5 amp batteries, but if you have multiple batteries and chargers (from acquiring multiple tools) you will never be waiting for a battery to charge. If you have only purchased Greenworks tools, then you are golden. BUT HERE IS THE RUB IF YOU, LIKE ME, THOUGHT THEY WERE STRAIGHT-ACROSS COMPATIBLE WITH THE SAME LINE OF TOOLS THEY MANUFACTURED FOR LOWE'S UNDER THE KOBALT MONIKER AND BLUE COLOR, AS DIFFERENTIATED FROM THEIR STANDARD BRIGHT GREEN. One of the reasons I went ahead and committed to buying the Kobalt line of 80v yard tools was because Greenworks made them and I figured that it would be a long-lasting and stable design platform, being the same 80v system across two different brands. Then Lowe's dropped the 80v line. I was able to get a few more of their tools for great clearance prices and looked forward to switching over to the complete line of Greenworks 80v tools. was very happy to be able to order their edger because it's the exact same power system - just that all of my gear is Kobalt blue. AND HERE IS THE DEAL WITH THAT: They are different. The Kobalt 80v battery will not fit/slide into the Greenworks 80v battery compartment/housing (*as manufactured). - I guess I shouldn't have been surprised - and it could have been Lowe's that required that the stuff made for them specifically would be incompatible. But since it's the same power system, I wondered what the difference was and if I could work-around their obstructionist corporate bs. What I discovered was that the battery compartment on the tools have two long molded channel-guides (male) that match the two long molded (female) channels in the batteries. The vertical placement of the bottom 'rail' in the tool/compartment is positioned in a slightly different spot between the Kobalt and Greenworks 'brands'. But this actually works, because I just used a hand chisel and removed the 'bottom' rail from the Greenworks tool/edger. WA-LA - EUREKA!!! It worked great! It's a great fit, the top rail is more than enough to hold the battery stably in position and the 'lock' mechanism functions perfectly! I am looking forward to buying more tools in the Greenworks 80 volt line without having to replace all of the Kobalt tools I already paid for AND ESPECIALLY the rediculously expensive batteries...

Great product that makes edging very fast
Size: 8" Edger New
Edging was quite a job because I had to do it with a hand tool. I have quite a few Greenwork tools, so I decided to purchase the edger. It works great and I am in general happy with it. The three downsides for me are that tool is quite heavy when it also has the battery in it, that the metal blade decreases in size rapidly because of the friction when edging near concrete, and that the wheel is in such a position that I have to bend substantially while the blade does not edge deep enough so that I have to lean the tool on the metal strip at the bottom of the tool.

Plenty of power. Easy to use.
Size: 8" Edger New
I was amazed at the power of this edger. Due to health issues we couldn’t give our lawn adequate attention. It hadn’t been edged in over a year. This edger cut thru the heavy overgrown grass. Maintaining the edging now is a breeze. It uses the same 80 volt battery as my blower👍. The only negative is there is no edge guide, but once I got used to it, it’s not really needed.
