In this video I reviewed the Kiwi Ears Belle, a single dynamic driver IEM that costs around 30 USD, and yeah—this is the kind of budget set that surprised me with how good the bass is. LinSoul sent it over, but as always, this is 100% my own opinion. I quickly go through the unboxing (tips, basic cable, simple packaging) and then talk about build and comfort: the shell feels solid with a metal faceplate, and even though I’m not a big fan of how it looks, it’s genuinely comfortable, slim, and basically weightless in my ears. Sound-wise, I tested it with the stock gray tips on my Poco M6 Pro (Apple Music) and also plugged it into the NiceHCK Octave. My first impression was immediate: the bass hits hard, thumpy, rumbly, and has real texture with a weighty body. Important note—this isn’t a “basshead” IEM, it’s a “nice bass” IEM with a Harman-ish tonality and sweet rumble down low, especially for rap/hip-hop. Mids are mellow and not shouty, treble is smooth and safe, and for 30 bucks the technicalities are good: small but symmetrical stage, decent separation, 2.5D imaging, and it’s even good enough for FPS gaming.
