Westone B30 Triple Drivers IEM Earphones with Bluetooth Cable

This headphones are truly noise counseling. The sound quality is great.

Took me a while to decide to write this because I realize Westone is a very successful company and has gotten that way with their design strategy. This design strategy it seems, among other things, favors intentionally "tuning" the sound of different headphone models to certain tastes. I am not therefore going to rate these headphones based on the turning decisions that Westone made; that's personal preference and subjective. That being said, I believe there are certain things that are hallmarks of a good speaker design. In the case of a speaker, such as the B30, that places emphases on lower frequencies that hallmark must include the ability to deliver those lower with good transient response. Failure to do so delivers bass that sounds like a muddy mess. Ever hear those cars with the sub woofers in them "bah-bah-boom-boom-boom-bah-bah boom" ...and on and on until the cars sounds like it will be shaken apart? That is an extreme example of a speaker system that emphasizes low frequencies with TERRIBLE transient response. The B30 don't sound like that; they do not have *terrible* transient response. They do however, in my opinion, have *really bad* transient response. Now I understand it's hard to design a small speaker (i.e., headphones) with good transient response in the lower frequencies. To do so you need to move a lot of air quickly and stop moving that air quickly: that is really, really hard to do with a small speaker (i.e., headphones). But come on: it's Westone! They could have done better than this. Way better. How do I know? Because other IEM can deliver lower frequencies with really good transient response. The HIDIZS MS4 (for $120 less) is an example. What's worse, bad transient response can't be corrected with equalization. You are much better off buying IEMs designed with *less* emphasis in the lower frequencies and good transient response in those frequencies. Why? Because with that combo you can you use an equalizer to boost the low frequencies you want and have excellent "bass head" sound.
