So, you remember PSB, right? We told you about their headphones, and even reviewed a pair of their over-ear noise cancelling ones (you can see that here). Just recently they introduced two new additions to their M4U lineup – the PSB M4U 9 and the PSB M4U TWM.

To use, the PSB M4U 9 looks like a solid continuation of the M4U 8 series (which we reviewed). And frankly, that makes sense – when you’ve got a solid design, why mix things up too much? Our belief here is that most of the improvements are happening inside of the cans, so the exterior can continue on.

Then you’ve got the PSB M4U TWM, which are undoubtedly going to be a higher-fidelity reproduction than whatever inexpensive wireless earbuds you might have kicking around. You’ve got planar technology for the drivers, and actual, clicky buttons on each earbud to control what’s going on.

Of course, both make use of the Audiodo Personal Sound tech, which is in the associated PSB app on your phone. With it, you can tune the sound profile to what your ears – left and right are tested separately – can actually hear. It’s a very specific level of customization, and makes for great audio, whether you’re listening to music, podcasts, or even calls at work.
