The FLC Shirasawas are a new release by FLC Technology, which is most well known for the FLC8s tunable IEMs that was released back in the mid 2010s. They don’t release new products often. The Shirasawa is a 1DD 4BA driver IEM that retails for $250 USD. My source used for review is the Lotoo Paw Gold Touch.
The packaging comes with a puck style case, a copper cable and six pairs of silicone tips from XS to XL. The variety in sizes is nice to see. The IEM themselves have this snowy texture on them which looks pretty cool.
Bass:
The bass is probably the best part of this IEM. It’s got a good amount of midbass, and the bass has good depth, texture and slam. It also has a nice amount of subbass extension and rumble as well. The bass quantity might be much for some, but I don’t consider it basshead level exactly, just harman level bass.
Mids:
The mids are pushed up a bit for the upper mids, as is the typical harman / w shaped tuning. They have nice texture to them especially considering the price point these retail at.
Treble:
Treble has good extension and detail, and do not sound harsh, sibilant or fatiguing at all. Overall the treble is also tuned quite nicely to balance out the bass and mids.
Technicals:
The detail and soundstage of this $250 IEM rivals that of a $1k IEM like the Dunu Glacier and ThieAudio Monarch MK2s. It punches above its price in technicalities, and is very impressive.
Overall I cannot say much negative about this IEM, it is a fantastic value IEM that will appeal to people who listen to mainstream pop and vocal music. It’s got a nice harman / w shaped tuning that will work well for modern music. The technicalities impress me the most at this price point as it rivals alot of $1k IEMs that I have tried before. I wish this brand would get more attention!
