Whizzer is a well established earphones company, they have release interesting hybrid IEM as well as a great single dynamic IEM, the HE01, which have a solid fan base even nowadays. Today, I will review their entry level single dynamic earphones, the BS1, which promise to offer excellent sound value with it’s 13.6mm composite dynamic driver. Let’s see in this review if this assumption reflect the truth.

CONSTRUCTION

Firstly, the BS1 is a cabled IEM, so for those only buying IEM with detachable cable, it will be a drawback. This cable is made of nylon material that can keep it’s bent too, which is anotther drawback but it isn’t as much prompt to microphonic as other type of cable ,which is a plus.

The shell is a true open back and it’s made of half-metal half-plastic, it look good and the fit is easy, but as expected with open back, sound leakage is noticable. In term of accessories, we have the strict minimum. But for the price their nothing to complaint since construction doesn’t feel cheap or overly fragile.

SOUND IMPRESSIONS

TONALITY is a balanced slight V to mid centric, with warm bass slam, hint bright mids and an analogish overall presentation. What is analogish? Let say a lush thick cohesive timbral and tonal balance that feel organic as a whole.

TECHNICALITIES are good for the price, but average in sub-100$ price range. Resolution is a bit dark, attack lack control and snap and separation is blurry.

SOUNDSTAGE is the star of the show here, thanks to open back design, it feel very tall and wide, with an appealing holographic feeling to it but a lack of deepness.

IMAGING is very average, this is due to blurry micro definition and lack of clean space between instrument, but the sound layers are well extract and wide in presence.

BASS is the most boosted part of spectrum, it have a weighty warm slam to it, not a tight punch, it’s rather slow and will bleed on mids in a romantic way. Definition and separation lack clarity and accuracy, and their an airy resonance to bass line that tend to affect tone of low range instrument. Extension is roll off just a little, and it lack lean natural flexibility. To me, all the issue that happen with BS1 tonality is due to the sloppy bass impact and warm boumyness.

MIDS are quite addictive, lush with a natural timbre to it, and open in presence which make us think the BS1 is mid centric sometime. Both male and female vocal sound full and are free of upper mids sibilance, yet they have beautifull breathyness to female vocal that add density. This isn’t thin sounding mids, but resolution and separation is average as soon as more than one instrument go on.

Treble is smooth, delicate without feeling too dark or lacking in bite. Violin sound great and the attack is felt, with a realist tone but short decay. Electric guitar too sound OK, though not very textured they don’t sound thin or wonky. Attack is where the problem happen, it lack snap and sparkle, brilliance is there but minimal. Some percussions can get lost in the mix too, but clavichord sound decent. Drumstick is more fowards than other percussions too, so their a slight spike somewhere. Still, it isn’t harsh treble nor overly splashy, just not very refined.

COMPARISONS

VS Tanchjim TANYA

Tanya is warmer and darker, timbre is more natural and smoother, bass is warm but better rounded, less sloppy, with a tighter mid bass punch impact. When it come to technicalities, Tanya show it’s limit, imaging is more mixed up, soundstage is less open and airy, treble is more rolled off. Overall, Tanya feel more V shape making the BS1 sound W shape and even a bit bright. Resolution is superior with BS1. Timbre isn’t as thick, but transparency is better.
To be honnest, their no clear winner here, it will be tonal preference even if BS1 have upper hands when it come to technicalities.

VS FIIO JD3

What hit first is how less bassy are the JD3, but they have more extended bass response since mid bass is leaner. Brighter, more W shape and analytical too. Timbre is notably more thin and artificial but this keep resolution clearer cleaner too. We have more micro details and more air, but overall musicality isn’t there compared to lusher less cold-clinical BS1. Treble have more sparkle decay with the JD3 too.
Here it’s the JD3 that have upper hands for technicalities, but it would surprise me anybody find it’s tonality more pleasant than BS1.

CONCLUSION

The Whizzer BS1 offer a very immersive musicality with a big airy soundstage, it have this unique ”analog holographic” sound presentation that make it very addictive. While it’s no master of technicalities, it’s still above average in it’s price range due to nicely layered spatiality and overall good macro-resolution. It’s hard to not suggest the BS1 for it’s price, since it offer a sound experience no other IEM offer in this price range and even above, in the sens you feel like being in a big room fullfill with big speakers delivering a bigger than life musicality in a small IEM shell. Why not spoiling yourself with such a pleasant immersivity?
