Speaking of subs for low end, I'm currently enjoying the Woojer Edge vest, basically haptic feedback you wear. It's far from hifi in its current iteration, however, it does have some range in bass, so you do feel sweeps and drops pretty intensely. The thumps are also timed fairly well, so you feel more of the kick drum. I know there's a more pro-audio focused type of this called the Subpack X1, but it's currently on preorder only. I am looking forward to trying that!
It works great on most pop, hiphop, or electronic type music - even some jazz I've tried where the upright bass groove really moves you. When I play either of Billie Eilish's albums, it almost feels like they have an additional track you have never heard before specifically for this type of haptic feedback. It works amazingly well and it's extremely addictive. The Pino Palladino and Blake Mills collaboration, Notes with Attachments, was made for something like this.
I think we'll be able to pair our headphones with real hifi bass/lfe we can feel without disturbing others in the next year. Again, I don't consider the Woojer hifi mainly because it's not very linear and is made more for fun, but maybe the Subpack will impress me in that aspect.
I'm listening from my TT2, feeding both the Woojer Vest and the Abyss right now. I look absolutely ridiculous, but this Blade Runner soundtrack has never sounded (felt really) this good before.
