My only currently owned Focal is an Elegia with leather pads, sounds similar to the Celeste. I've also owned the Celeste, Clear OG, and Radiance.
Disclaimer, I run my headphones on R2R dacs and tube amps, which will give a smoother more analog presentation vs delta sigma and solid state. This setup favors ZMF more than Focal IMO due to dampening factor (Focals are relatively low impedance vs ZMF).
The Bokeh is not as aggressive sounding as any of the Focals I've owned. It's very dynamic and powerful, like the Focals, but somehow is smoother and less fatiguing. I really enjoy Focal's tuning, especially the Clear OG, but it fatigues me. They all do to some degree, unfortunately. I get none of that with the Bokeh. It's not as tight and precise as the Focals, but more engaging to me, and similar dynamically. Even on my iFi Zen stack the Bokeh is smooth and non-offensive. It is a warmer tuning vs the Focals, even the Radiance. It's thicker and more powerful sounding, though you can cool it off significantly with pad and mesh rolling.
The closest Focal I've heard to the Bokeh would be the Radiance. I MUCH prefer the Bokeh. I enjoyed the Radiance but found it would fatigue me if I tried to listen for more than an hour or two. I listen mainly at work so listening time can be 8 hours or more a day. When I had the Radiance I would listen for maybe an hour, stop for an hour, then start again, so on and so forth. The Bokeh stays on my head all day without fatigue.
