The included eartips don't work well for me, I use the BGVP A08 which balance the sound while keeping spatiality wide open enough....as well, it match the dark blue housing very well.

The HOLA has a slightly faster bass, but in other technicalities (imaging, instrument separation, micro-details, soundstage), the Z300 is superior. Compared to Z300, Cadenza sound profile has a more neutral approach as it has mild-U shaped tonality. It has less punchy and tighter bass response but it has cleaner quality, it has a more neutral and a transparent midrange with just a sufficient warmth on it and a similar treble response but it has a tad shimmer to give a sense of clarity and detail. This applies for most countries. However, large items such as headphones and desktop DAC/AMPs (e.g. HarmonicDyne G200, MUSICIAN MDP-2, and etc.) are excluded. Usually I put all new arrivals on the burn in rig for at least 150 hours, not because I am a strong believer in burn in but because it doesn’t cost me anything to do so while they wait their turn. In this case, no burn in was done ( ) but I really don’t think that should be a concerning factor for those who feel it is necessary, as my opinions are positive, so unless it was supposed to get worse… And their come the Blon Z300 I will review today because of my hope revival that HBB can help Blon to achieve a decent tonal balance, something they struggle alot with numerous post-BL03 release.

Blon Z300 Packaging:​

Technicalities: Sound Stage 2/5, Image 2/5, Layering 1/5, Separation 2/5, Details 3/5, Resolution 3/5 Megatron - I noticed that the response from the pairing with Megatron was becoming more transparent and lucid as I listened to it. While the bass response became more sub bass obsessed, the details and energy in the treble and mid range became more sophisticated. The stage got a little bit narrower while the imaging and resolution got better. The way the notes were divided up still felt the same. The technical performance felt the same aside from that. The treble region has sibilance, but it is rarely audible. I like the details, but I'd still rather pair the Z300 with the V6 because the transparent response lowers the tonality and makes the IEM sound generic. Something to keep in mind is that the Z300 is a headphone with safe, comfortable, non-fatiguing highs. However, there is a slight peak at 8 kHz that can hurt ears sensitive to this frequency region, especially at higher volumes.

The BLON x HBB Z300 uses a state-of-the-art 10mm silicone diaphragm for an accurate, clear and natural sound. This diaphragm is engineered to offer the perfect balance between rigidity and flexibility for incredible detail that showcases a powerful sound that’s authentic while staying nuanced. SR5 is well equipped with quality components and Tuned to be a clean sounding iem with lots of details.it is all about Mids and Highs.the "Knowles Balanced armatures, (used in expensive chi-fi iems) are the star of the show.for the mids i can hear Here in terms of technicalities, I found it very similar to the BL03 , and below the BL07 , if we consider other BLON models that I know. In other words, it is a phone that has an interesting stage, but is restricted only to the sides, with minimal or perhaps non-existent three-dimensionality.

Comparisons were made with other budget single DD IEMs. Planars, hybrids and pure BA types were left out of the equation as the different transducers have their pros and cons. Focusing on something more electronic, such as “ Sun Is Shining”, I think the bass range works fairly well and while it may not be enough for those who like skull rattling bass, personally I feel it has a decent balance with the rest of frequencies to place the focus on those bass notes without taking over the whole spectrum.

You can see how weak the bass is on the z 4, if you like bass it's hard for the z 4 to compete with the z300 Finally, I will only evaluate the Z300 based on their performance, even though I will explain how it feels and seems physically and aesthetically.I used the BLON Z300 without any discomfort. Its body is smooth, with no sharp corners, and although the short nozzle forced me to use L-tips with a shallow insertion, I don't consider this a problem. Its seal is very good, and there is no pressure on the ear canal. Mids is where the Z300 differ quite alot, it's fuller, warmer, smoother with a more natural timbre and less upper mids sibilance and texture brightness-grainyness than BL03. But it's darker and less open sounding thant BL03 too, definition edge is more blurry and softed and overall resolution is less transparent. Mids dynamic is leaner with the Z300 too, vocal and instrument being less agressive in loudness.
