being a long time OP-1 owner iāve had 3 of these, i think i might have this exact one. will share some unsolicited tips that would have been helpful to me at the time (that maybe i am presently wrong about and would be good to find out if so!):
āthey can be pretty fragile! i bricked my first one dropping it 3 feet onto hardwood. that company was nice enough to send me a second one when i complained, which also ābrokeā somehow, leading to me buying a third one from a different brand (i think the one linked? but they all look the same so not sure).
āat some point i discovered that the second one didnāt actually break, it just shipped with cables that were on their way out. could have saved myself (and the planet) a little hassle.
āthis is the most controversial, but i feel like i can still hear the difference in quality between 1/8th direct out no USB and usb charging + 1/8th in to loop noise isolator. like a small amount of hum is sneaking through around -48db or whatever. very real chance this is placebo though since these are teenage engineering products and thereās gonna be noiseā¦
