IK Multimedia has entered the headphones amp market with the Tonex Plug, and pocket-sized guitar rigs don’t get more powerful than this.
The form factor is familiar. The Tonex Plug has the integrated 1/4” input for your guitar cable in that swivels to accommodate most (all?) electric guitars. There is the 1/8” output for your headphones. And there is a USB C input for charging the device. You can also use it as a guitar audio interface.
