BLON 4.4mm Upgrade Balanced Cable: A Sound Quality Improvement at low price

I bought the 4.4mm BLON 4 core upgrade balanced cable for my BLON HBB Z300 IEM. I definitely noticed an improvement in sound quality with the balanced cable, as it provided a wider soundstage and more detail. However, the stock cable is much better made than the upgrade cable. The upgrade cable is more prone to tangles and feels less durable.

Overall, I would only recommend the upgrade cable if you are looking for a 4.4mm balanced cable for your Blon IEMs with QDC type connectors (Blon QDC types are different from other brands such as QKZ, KZ, etc. and does not fit with cables from these brands). If you are happy with the sound quality of the 3.5mm stock cable, I would recommend sticking with it.

Please note, any other 2 pin type connector cables will work with the Blon IEMs, except they do not fit properly like the stock cable and they can be costlier than the BLON 4 core upgrade cable.

On a side note, Thank you to Concept Kart. The service and delivery was really quick and hassle-free, definitely a 5 star service.

Music Producer's review

Hello 👋 I am a music producer. recently bought this product (Blon BL03) and here is my review
1- Buil quality is really reliable. MIC's performance is good. comes with L shaped jack.
2- Sound quality matches the hype. very sound separation and best for EDM lovers
the lows and highs are slightly over for those who want a balanced sound signature
1- Earbuds feel quite heavy and hard to hold
2- and it comes with really very bad ear tips feel hard plastic. so, for comfort buy third party ear tips
