THE PWS.01
The PWS.01 weighs just 636g and is really not very large measuring 180mm in length, 60mm in width and 80mm in height. As you can see the front and rear of the enclosure are made out of rubber and not wood.
Grain Audio has engraved their logo on the left side of the enclosure.
We were somewhat surprised to see that aside the on/off/pairing LED button with the G letter on it (also behaves as a battery level meter by changing colors) there are just volume control buttons available and not the usual next/previous track ones (not that we really mind since we hardly ever use those buttons anyway).
The 3.5mm and microUSB ports are both placed on the right side of the enclosure.
As clearly shown in this image the PWS.01 sits on two long rubber feet which are basically extensions of the front and rear rubber sections.
You can find several certification icons, the country of manufacture and the electrical requirements of the PWS.01 on the sticker placed at the bottom.
Thanks to the above marketing picture by Grain Audio you can see the location of the speakers and the passive radiator.
