Quality build, Compact and ergonomic design, Removable cable, Above average technical ability
Slightly muddy bass, Strained, Off-timbre midrange
The BL-05 isn’t a bad buy when taken holistically, but does receive a limited recommendation from me for its polarising tonality.
Blon really took the audiophile world by storm with the BL-03. Though not especially impressive from a technical point of view, the $40 teardrop-shaped earphone carried a highly natural tonality, something not frequently found at such a low price point. As such, it quickly became the darling of numerous audio forums and for many, served as a gateway drug into the world of the empty wallet. The BL-05 follows hot on its heels. Redesigned from the ground up, Blon promise a more balanced, detailed sound and improved ergonomics, all at a meager $5 USD price increase. With a stainless steel build, removable cable and CNT dynamic driver, the BL-05 promises a lot more performance than its $43 USD price tag would suggest.

I would like to thank Nappoler from HiFiGO very much for his quick communication and for providing me with the BL-05 for the purpose of review. All words are my own and there is no monetary incentive for a positive review. Despite receiving the earphones free of cost, I will attempt to be as objective as possible in my evaluation.

The Pitch –
2nd Generation CNT DD
CNT drivers have been observed at the high-end of IEM design and are now filtering their way down the price ladder. The BL-05 promises strong performance and low-distortion with a new diaphragm design with a carbon-network framework serving to increase rigidity and agility. Blon also boast an almost linear impedance response.
The BL03 achieved notoriety for its natural tonality and smooth FR. The BL-05 promises the same with a custom-design interior acoustic chamber. Alongside its new driver, Blon promise and audiophile-orientated tuning with a natural presentation, wide soundstage and coherent imaging.
The unboxing experience reminds me of most Chi-Fi IEMs, the earphones are showcased through a clear window while the accessories are stored in a box below. Included with the earphones is a stylish canvas pouch, not super protective but a pocketable case that will precent deep scratches. Blon also include 2 types of silicone eartips, 3 pairs of generic grey tips in addition to two pairs of Spinfits, most likely CP155’s but the material is different to the latest generation such as those included with the Fiio FA9.
A prime area that Blon spent refining over its predecessor, the BL-05 features a stainless steel construction with a pod-like design reminiscent of AKG’s high-end earphones. Users have the choice of black or silver chrome housings, all with premium gold accent faceplates. It’s an impressively well-realised housing, especially as they were design in-house. Of course, the finish cannot compare to higher-end metal earphones with some orange peel on the paintjob to name an example. However, they are well formed with smooth seams and very reassuring density in the hand. A thoughtful addition includes left and right markers on the faceplates.
They use a 0.78mm removable cable system that is a great luxury at this price point and will ensure a longer lifespan for the earphones. The connectors protrude with inset pins on the cable to provide additional support while still permitting compatibility with third party units. The cable itself is of acceptable quality, the jacket is tacky but highly supple and the connectors all have excellent strain relief. Unfortunately, the wires themselves are very thin which makes them more tangle-prone to most. Nonetheless, the cable is not microphonic in the slightest and the pre-moulded ear guides are comfortable and stable fitting.
Fit & Isolation –
One thing that can be difficult to judge in photos and renders is scale. The BL-05 is a tiny earphone and very low-profile. As such, buyers looking for an earphone to sleep on may find this a very suitable choice. The nozzle is on the shorter side so most users will have to either size up tips or just longer tips such as the included Spinfits. Combined with the small housings, this contributes to an exceedingly comfortable wearing experience with zero hotspot formation.
I also found the seal to be quite convincing and, alongside their over-ear fit, they are very stable despite being slightly heavier due to that stainless steel construction. A vent is present, though as it lies on the inner-face, wind noise isn’t exaggerated when wearing the earphones outdoors. Isolation is above average but certainly not outstanding. They will suffice for commute but will struggle in loud environments such as the metro.
