FatFreq are Bass Cannons
The fit ear fit is great no harshness or irritation after long periods of wear. The sound of bass is excellent without overpowering the treble & mid-range sounds! In a word the sound is balance. The price to is competitive even with top tier IEM brands...

This is what I have been seeking.
I add a bass shelf to every headphone and IEM I own. Not this one. It is perfect! Well the mids and highs could be a tad more refined but they are listenable and haven't heard anything else since they arrived.
