Right off the bat, and assuming the renders are accurate, the WF-1000XM4s look very different from its predecessor. The WF-1000XM3s had more of a pill-shaped design, but with the fourth gen model, Sony has opted for a more rounder design which should make the earbuds less obtrusive and won’t stick out like a sore thumb in your ear.

Sony is however sticking to some of the previous design, namely the accents where the black model has bronze-ish accents like it did in the previous model, which we say actually looks pretty good. So far only two color options were leaked and we’re not sure if there will be more options, but based on the WF-1000MX3, probably not.
The renders also show off a newly-designed case that does away with the cover accent for a sleeker look. There are no specs accompanying the release of the renders, so we’ll have to wait for the official announcement, which given the leaked renders should (hopefully) be soon.
