FLC 8S…they have adjustable sound via various filters you can swap around.
great bang for buck, many commendable reviews.
however can’t adjust by any ios app, sorry
the owner, creator, Forrest Wei has a good back ground in audio.
‘‘FLC Technologies was started by Forrest Wei not too long ago (in 2011), he has many years of experience working for Ultimate Ears, Jabra, MWM Acoustics, and Harman.With all this experience under his belt and fueled by a passion for design and innovation, Forrest made a serious attempt to reinvent the wheel of IEM sound tuning by using multiple filters in his debut release of 3-way hybrid FLC8, later replaced by FLC8S with improved build quality and updated cable. Now, with a support of Teo and his Lend Me UR Ears, they are taking it to yet another level with soon to be available Custom model which I had a chance to test and would like to share with you about.’’
