Blon BL-03
Price range: ₹ 1,999.00 through ₹ 2,033.69
Blon BL-03 with its 10mm carbon diaphragm dynamic driver unit offers a balanced sound signature with an enhanced bass profile. Blon BL03 is made of a die-cast metal shell with smooth edges. It looks so beautiful with its mirror polishing, which is anti-scratch, and anti-skid. It comes with a 2-pin detachable cable. Many people mistake it by calling it Blon 03 whereas the correct calling should be Blon BL-03.

Worth the Hype! Worth the Wait!
Blon BL-03 has a massive sound, with good staging and separation. Bass is big and controlled, mids though receded compare to the bass but clear with focus on upper treble, Treble is just perfect not much to be bright and sibilant and have plenty detail retrieval and timbre. That’s what a magic of tuning does to a single dynamic driver unleashing its full potential.I am using it with my dated Asus soundcard and Fiio E17k+ E10K combo and no other IEM sounded so perfect from the get go, comparing to my usual daily drivers E10c, E50c, VE monk+ and Dunu Titan. These blows them all away.
Kudos to Hifinage to deliver this beauty during these partial lockdown.

Miraculous tuning, lush sound, amazing value
Subjectivity and taste aside, I’ve found Bad Guy Good Audio’s reviews on YouTube to be on point – less superlatives, more in-depth analysis. So when he explained how well tuned these iems are and walked through the frequency response, I knew I had to try these.
Prior to these, I’ve owned a number of the usual Chi-fi suspects: Tin Audio T2, KZ ZS 10 Pro, some Xiaomi wired earphones (original Piston 3 Red-Dot award winners, Piston ProHD), some SoundMagic iems, as well as some non-Chi-Fi stuff: AudioTechnica cans and iems, Sennheiser CX series etc.
These are an extremely competent pair – it has an overall warm sound signature (lush mids), with great extensions on both ends, perfectly suited for long listening sessions without fatigue. A number of reviewers on other sites have mentioned slightly recessed treble and accentuated bass, which for a treble-head like me would be an outright deal-breaker, but that is not what I found. Highs are fantastic and I talk about them below. I will also draw some comparisons with the Tin T2 (my current main iems).
Setup: Foobar2000 + Fidelizer + 24/96 usb dac, all FLAC sources. Occasionally, Equalizer APO + VSTs when a certain track needs some special EQing.
The low end response is articulate and fast – great punch with no bloat / muddiness (a problem with many KZ iems), and there is no mid-bass hump either – nothing here bleeds into the rest of the spectrum. The mids are the highlights: lush sounding and well controlled – not too forward, and not recessed either – they are done just right – vocals sound great, and detail retrieval / instrument separation is great. Coming to the highs: I’ll just keep it short by saying that they respond very well to EQ, so you can season to taste they way you like it. For those of you (myself included), who love that sizzle and sparkle without sibilance / graininess, slide those 12k-16k faders up, these will respond well. It’s only out of the box in their default tuning that these are a tiny notch less sparkly than say, the T2 or the T2 pro (which is even more treble heavy).
Short comparison with T2: Much better bass without any attenuation, highs are less grainy, less sibilance too, long listening sessions are not as fatiguing (at least for me).
Additional notes:
– Don’t bother with the provided tips. Use your favorites and ensure a good seal.
– I bought the variant with the mic. I tried with custom mic-less cables (I have a bunch of these), the difference is too subtle to bother about. Also, microphonics is not an issue.
Overall verdict: With the market getting flooded with options in the sub $50 category, these are a refreshing break and a pleasant overall surprise. Utterly brilliant default tuning, great response to custom EQs and a sound signature that will please the overwhelming majority. A steal for the price, these match and even exceed many iems twice / thrice its price. Worth getting a backup pair.
