Are you saying that the IE600 comes close to the Origin in the impactful bass department? I listened to the Origin at the CanJam and I really liked it. I would love pick one up but I wanted to spend less than $850.00 (now probably over $1k with the stupid tariffs). Used IE 600 can be had for around $300.00.In the long run, the Sennheiser IE 600 are always a safe choice. They sound perfect to me and are very comfortable - the sound is rich and powerful. I simply love them!
I've had the Thieaudio Origin for a few days now – they sound fantastic, with very smooth and detailed highs without any sibilance, excellent imaging, and perfect bass. They're just as powerful as the IE 600.
