I thought some of you would find this measurement comparison interesting -- it's the Focal Stellia frequency response compared to the
Harman AE/OE Target* (to read the paper in full requires purchase or AES membership):
For my preferences, in terms of tonal balance, the Focal Stellia is perhaps my favorite closed-back headphone for general listening pleasure. While the Harman Target is certainly not the only sound signature I like, headphones that are Harman-AE/OE-Target-ish (and IEMs that are Harman-IE-Target-ish) seem to reliably be among those I enjoy listening to.
In terms of imaging, I feel the Focal Stellia images precisely, coherently, and relatively airy for a closed-back headphone. However, when it comes to image size and perceived openness, the Sennheiser HD820 and Sony MDR-Z1R remain the clear frontrunners to me. (And between those two, I'd give the edge to the Sennheiser HD820 in this regard.)
Versus the Sennheiser HD820 (with its
very large ear pads that are relatively firm), the relatively smaller footprint of the Stellia with its very cushiony, pliable earpads will likely make achieving a good seal much easier to achieve for most users (which is very important especially with closed-back headphones). While I can get a good seal with the Sennheiser HD820, reading community impressions over time suggests that some find it challenging. I think this will be a very rare issue with the Focal Stellia. In my opinion, the importance of this cannot be overstated.
Since shooting the
Focal Stellia video, my enthusiasm for this headphone has only grown. The Stellia is my favorite of all of Focal's headphones. And while the closed-back Stellia unquestionably (and unsurprisingly) gives way to its open-back siblings like the Clear and Utopia in terms of pure technical performance, resolution, and imaging, its tonal balance is strong enough (for my preferences) to push it well to the front of Focal's now quite-complete family of headphones. (Again, this is relative to my preferences and priorities, and those who rank all of these factors differently may (of course) come to different conclusions.)
Also, following are the measurements that were shown in the video:
