Yinyoo KBEAR Storm in-Ear Monitors
Overview
The KBEAR Storm is a budget-priced single dynamic driver (1DD) in-ear monitor (IEM) from Yinyoo, designed with the aim of bringing high-fidelity sound to musicians, performers, and everyday listeners. At just £17.99, it promises impressive specs for the price — including a detachable silver-plated cable, a 10mm magnetic driver, and multiple eartip options.
We were intrigued. Unfortunately, when it comes to bass — the one thing that really matters for this site — the KBEAR Storm fails hard.
Pros
- Good Build Quality: The plastic housings feel well-made and solid, especially at this price point.
- Comfortable Fit: Lightweight and ergonomically shaped; they stay put during long sessions without fatigue.
- Attractive Design: Available in several colours with a sleek, modern look.
- Decent Accessories: Comes with multiple eartips (6 pairs in 3 sizes), which helps with fit and isolation.
- Quiet Cable: The over-ear cable doesn’t transmit rubbing noise, and it’s removable, allowing for upgrades.
Cons
- Lack of Bass Response: The biggest issue. The low end is practically absent, and even EQ boosting doesn’t help much.
- Tinny Sound: Without low-end support, the overall sound signature leans heavily toward thin and brittle.
The Bass Test
As a bass-centric review site, we’re always evaluating IEMs by how well they handle low frequencies — both for listening and monitoring live bass. The KBEAR Storm, despite manufacturer claims of “powerful and affecting bass,” simply does not deliver.
No matter the source — phone, DAC/amp, or EQ tweaks — the low end remained thin and lifeless. Boosting 60–100 Hz did very little. Even 500 Hz boosts to recover warmth didn’t add punch. For bass players or fans of bass-heavy music, this makes the KBEAR Storm unusable.
Verdict
If you’re on a tight budget, mainly listening to podcasts, or using a Samsung phone with Dolby Atmos and you don’t care about bass, the KBEAR Storm might be a comfortable and affordable entry-level IEM.
But if you’re a bass player, a music producer, or just a fan of heavy low-end, these are not for you.
