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. ### ⭐⭐⭐⭐ 私の好きな音質 *by コ***ツ on Reviewed in Japan on November 30, 2019* 好みによって違うと思いますが、私は好きな音質です。買って良かった。ゼンハイザーのIE80が壊れたので、この機種に乗り換えました。低音寄りのチューニングはIE80 に近いと思う。ゼンハイザーより音の余韻が少なく、楽器の音が聞きやすいシャープな印象。低音が強いがぼやけた感じがなく、自然に強調されている感じ。高音もよく出ているが、若干ノイジーに反響している感じがする。中音域に音が集中すると聞き疲れしやすいかも。全体的には気に入っていて、クラシックからロックまでオールマイティに使える機種だと思う。ーーー追記エイジングが進んでからの感想低音が綺麗なのが印象的ですが、中音から高音にかけてのバランスがとても良いです。そして中音域の響きが綺麗で解像度が高い。いろんな楽器の鳴っている空間位置も聞き分けられる解像度があります。付属のイヤピースもコンプライ型とシリコンの短いタイプ、シリコンの長いタイプと豊富で、イヤピースによって音がかなり変わります。私のお勧めはシリコンの長いタイプ。解像度と空間の広がりが向上します。 ## Frequently Bought Together - Westone B30 Triple Drivers IEM Earphones with Bluetooth Cable - Linsoul Tripowin Zonie 16 Core Silver Plated Cable SPC Earphone Cable for BL03 TRN V90 V80 AS10 ZS10 ZS6 ES4 ZST ZSR iems (2pin-0.78mm, 3.5mm, Grey) - SONICFOAM Memory Foam Earbud Tips - Premium Noise Isolation, Replacement Foam Ear Tips, 3 Pairs for Airpods Pro (SFAIR, S/M/L, Black, Tester Pack) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/128943579-b30-three-driver-true-fit-earphones-with-high-definition-mmcx](https://www.desertcart.com.ar/products/128943579-b30-three-driver-true-fit-earphones-with-high-definition-mmcx) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-23*
