Whizzer is a Chinese company who is flying the under the radar since their launch but while this Whizzer BS1 review is the last part of their high fly attempt, they need to correct some mistakes.
I am not using an amp with BS1 because its price ($25) is making the amp usage illogical. But if I push further to give it flying colors, a dongle would do fine – if not an amp – and while there is a recent excellent example with that price (named as Tripowin Lea) it’s only slightly above the average (truly better than a deep V shaped budget KZ).
Sweet and smooth experience
Easy to drive and get good results
Wide soundstage and airy to an extent.
Producing fantastic results on live recordings considering its price
Good for the budget range and in many genres in the end
Mids are under a thin veil
Detail reflection is so budget (bad)
Cable noise is very annoying
Rough in delicate music
Bass is boomy at smooth jazz
Whizzer BS1 is clad in metal and there are dual venting meshes at clever spots. Short nozzled. Laser etched words about its brand – driver and the designer. Nice professional touch. This is just its driver unit. Cable is cloth covered and prone to microphonics. Y split and first connector are in black and thin. Okay for it’s price. No chin guard too.
|Driver: 13.6 mm composite diaphragm|
|Impedance: 18 Ω|
|Sensitivity: 109 dB/mW|
|Frequency Range: 20-20,000 Hz|
Whizzer BS1’s timbre is neutral to very slightly bright. Presentation is forward as expected from any other budget iem. Details and micro details are low.
Basses don’t punch hard even at 100/100 volume at Daft Punk – Get Lucky. This is showing the need for an amp but this need at this price is a minus point. And they lack texture probably due to it not using a LCP diagram like Lea that is reviewed before. However, the soundstage (width) is very nice. The radiators at the back of both cases are totally working. The sound level above is producing metallic and disturbing results when actual instruments begin. And combined with its drivers incapacity to handle tonality, that volume level is like crucifying BS1. Nevertheless, boomy basses in Modest Jazz Trio are just doing it to the band itself.
Mids do the job. Neither very good nor very bad unless I and the music don’t concentrate on lower mids. They (I mean all the technicalities which happen in MID band) are just okay. A smooth experience. But I can hardly hear the crowd. And the clarinet seems under its tonality. Vibrato’s touches aren’t resonating like they should. The bell ring-esque treble isn’t with me. Piano keys are uber smooth too so they are losing the 3d effect. Extensions roll off fast and lifeless. The attack of the drummer’s full whole set at 08:00 in Limehouse Blues of Jazz at the Pawnshop is producing old fashion budget results.
Treble is not a weak spot of it. Tracks are not feeling weird to me as if they had jumped out of the window. But difficulties continue. They don’t have a fantastic resolution yet enough to keep going.
The first budget iem from a low profiled iem brand with a nice touch (air vent mesh) but IMO they should work hard on their minuses until – say – listening to David Gilmour turns into jazzy, blues and calm moments. But in the BS1 case, it’s a rough time for him. And this amp favoring driver structure is a misfortune match. This unit is supplied by keephifi in exchange of the non biased review.
