The Ploopy Headphones includes a fully-assembled, fully-tested set of headphones and an amplifier board. Note that you will have to do about five minutes of easy assembly work before the Headphones can be used. This is strictly so that we can package the Headphones more easily during shipping, and no tools will be necessary to complete the assembly.
Included with every set of Headphones:
- Ploopy Headphones, tested for frequency response
- Amplifier, programmed and tested
- TRS cable Y-splitter
- 2x TRS cable
- Wire wrapper
- USB-A to USB-C cable
You can find the full technical documentation on our Github wiki. The documentation includes how to change the EQ of the amplifier board, how we measure frequency response, full assembly instructions, and many other things.
The Ploopy Headphones signal chain is as follows:
- The Ploopy Headphones are plugged into the Amplifier board via TRS cable.
- The Amplifier board provides signal amplification and on-board EQ.
- The Amplifier is plugged into a computer via USB. USB provides power to the Amplifier board and Headphones, as well as the digital audio signal.
Note that the Ploopy Headphones are not particularly portable, as they require a large amount of power. Plugging them into a mobile device will likely drain the device’s battery quickly.
The Headphones headband is adjustable for larger and smaller heads. When you order, you’ll choose whether you want a “large” headband or a “small” headband. The headbands are adjustable with sliders, but the headbands also have a selectable “clamping strength”. If you select a “large headband”, we will include some extra parts for you to switch it to a small headband if you like, and vice-versa if you select a “small headband”. Whatever choice you make will only impact what we assemble for you.
Want to load new firmware onto your Ploopy Headphones amplifier board? Loading new firmware is fast and easy, and doesn’t require anything except your computer and a paper clip (or tweezers, wire, or something metal and thin). Check out our guide on loading new firmware here.
Tuning the EQ on the Ploopy Headphones is fast and easy. The Headphones Toolbox is a powerful, open-source GUI created by George Norton that can be used to quickly and easily shape the sound of the Headphones. We highly recommend it.
We STRONGLY recommend that you do not plug other headphones into the Ploopy Headphones amplifier. The Ploopy Headphones amplifier board is specifically designed to operate with the Ploopy Headphones. You should consider it as part of the headphones, not part of your signal chain. There is a significant chance you will damage other equipment if you interface it with the Ploopy Headphones amplifier board.
An important note about volume: The maximum volume of the Headphones is one that we consider to be adequate and safe for extended listening. However, we have received feedback that these Headphones are not particularly loud. If you listen to your Headphones at what may be considered a loud volume, these Headphones likely will not deliver the volume that you require.
