Blon 03 is my latest catch ,bought from a Ali seller after two more items bought earlier
The first is a Nintaus DAC player (tested long ago ) and little later a BT earphone set Ezear that operated for very short time and then died
already read many reports from various sources before ordering it with very
good reviews and kept a few screenshots with its frequency response . A u shaped
in ear earphone with rather low levels of bass and trebles and good idea to replace
my nearly linear sounded Soundmagic E11c
(upgraded E10 with microphone. AFAIK this model won the award of WhatHiFi on 2014 and possible its newer model for its
Blon costed that time (Jan 21) at around 21EU pus shipping only a very good bargain price with Microphone cable . At the time of writing (2 May 21) the seller hugely increased the price into 45Eu but at 9/5 the price was restored again to 21!
It has been received around 2.5 months after the order and tested immediately showing bad audio I immediately told the seller and the next days i designed a drawing showing them its grave shaped response curve. the person in communication was rather unable to understand and started unnecessary questions by reduplicating my requests. It sounded with no bases but with increased lower trebles that stop in their middles.
This is nearly how it sounded in a graphic form. There is a peak on 3 kHz but the remain part above 5 kHZ was rather nil
After that I left them aside and tested a few times later with the same response and asked other users experience . All of them were very enthused with its sound. In the meantime the correspondence with the company was oriented towards faulty the Bluetooth ear pads.
The user guide uses very good and comprehensive easy to use engish.
Two weeks after I made a minimal experiment by replacing the thin tips with wider ones (T). They were the tips as provided by the Soundmagic model . It standard tip was replaced by a foam ComplyTM clone type. It adds some more bass than the standard tip including deep bass.
time I was also testing the sound . Each step of replacements provided a better
stage towards sound excellence The wide silicone
tip corrected the sound curve towards what most reviewers know but still the trebles were 'bleeding trebles but bassier' to my ears comparing to the SM E11 . The foam tip
provided even better sound with deeper bases. All these tips complied with the standard T400 size

The model has been then compared with two more models for this review :
- My main SM/ Soundmagic
E11c ie the E10 with built in microphone with Comply eartip.
- A Inkax EP01 model of only 8.5Eu with same eartip It was found from the local
market Also with microphone
- A 3.9mm audio splitter cable with two outputs
- Q3 my standard type recorder and player.Sounds are from my personal Malay music collection with increased trebles and the Chinese test songs included in the sold Nintaus SD card but copied in my Amoi player . I m a fan of Asian music sine my birth
|a bit messy table with the earphones and the connectivity cabling|
My results were
shows a relatively bassy neutral sound. Cross testing them with sounds from a Tescun
Q3 player and 2:1 splitter cable shown
(a) mini increase of basses over SM
(b) mini increases of low trebles again in Blon
(c) SM has some sounds that are near to the 15 kHz that are not audible in the BL
(d) same sound stage
(e) similar audio and span in parallel stereo listening with buds of the same channel The sound is shifting by 2/10 towards the BL that means around 1.5-2db* (read below for the process)
The frequency response complies with the drawings noted by other reviewers
|from primeaudio page |
-Inkax shown a bit higher and extended trebles over the BLON and lower basses. When using the (e) test the sounds the "correlation distance" is +3 for the basses to -4 for the higher trebles
Νοτιce that such type microphones is a compromise of testing earphones. They dont respond so well in lower frequencies but i think still they can do partially the job in the mid and higher freqs. This is a simple amateur approach to get some simplified frequency responses the easy way The professional approach costs more than 6000 Eu.
Verdict 4/5 : The Eu 21 BLON is still a very good earphone that goes the job very well but still cant compare the nearly neutral Eu45 Sound magic.
------My parallel listening idea---
this is my idea : the same audio channel with different bud in each ear.
I tried to keep as deep possible the buds in the ears
A further notice on the photos above . It was a rather funny experience to use these earphones. it took some time to get accustomed with these weird cables.I preferred not to turn the cable around the ear in order to remove and put it again asap.
idea is very simple : putting buds of
the same channel from both earphones in your ears Therefore you get a monophonic sound that is heard over your nose if volumes
are identical. Any variations of sound volumes in frequency components can shift this point towards the higher
sounded bud. You can now think of an linear axis with 0 for the middle point (nose)
and -10/10 for each bud In the following photo the INAX are in the left ear and he BLON in the ear at right
TRN vs BLON
|replacing the ST1 with the BL03 bud for test |
Now adding towards TRN ST1 that seemed to be very close to the BLON03 by chance, i tested them with the A/B switch with the following results:
ST1 was heard with a rather "flat" sound that introduces a sudden raise on the higher treble band towards to the ear . this is the band part that BLON cant play
BLON seemed to be quite richer in sound with a sudden raise on the 3 kHz band
Graphically using the BLONin the right ear and TRN in the left ear the graphic can be shown roughly with this picture
I have made
this idea many times over the years before testing various earphones
I would like very much if you comment below in this review with your opinions and my interesting I hope graphical method
Addition : after finding the bug with the BLON 3 that was simply the mistaken use of the mid- bud and changed into the widest tips, the sound was clearly much better and didn't fell from the ear. The buds with the wide 'sponges' offered even bassier sound with near to AKJ headphones audio quality Checking them with the Inkax model i found them to be quite treblier with both buds: their standard silicone tips and also with the large 4.5mm tips !
