I couldn’t resist after reading this thread - my pair arrived Monday from Amazon.
Initially I was underwhelmed - great detail, but little deep bass, and that shriek! The hump must hit my sensitive spot.
Tried some sheepskin angled that I got from Ali, which levelled things out a bit, but then I tried the brainwavz XLs that I got for my (much modified) k550s.
Surprisingly they fit well and are a good match for my BFG ears.
The microsuedes were smooth, but lost too much detail.
The pleathers gave the detail back but were too bass heavy, and mid bass ‘bloaty’.
The perforated pleathers had just the right bass, but still some bloat.
All three impressed me with how much they brought the bass up - I think the deep lip on these works to semi-close the baffle vents.
As a last step, I made a baffle piece out of 3mm wool felt (same shape as the Mayflower insert) and just loose-laid it into place.
Well! For me at least I think this is it! Treble is extended but never sharp, bass is deep but tight, mids perhaps a little recessed, but only a little, and all played against a very black background.
At the moment, I can’t find anything to nit-pick with them, but I’ll keep listening - I’m sure I can find something!
I’ll try & get some pics later.
Anyone else tried the XLs?
