Deepest bass on the planet... Listen at your own risk Review by Precogvision @ headphones.com There's really... nothing on the market that is this bass boosted... [with] this control under 300Hz. It rumbles your ear and you can feel that sense of physicality in the sub-bass frequency./p> Review by Gizaudio A true Basshead IEM without compromises... This is the only IEM I can think of that has this cannon worthy amount of bass to satisfy basically any Basshead imaginable Review by Crinacle This is a HEDONISTIC amount of bass... a ton of bass and yet very much well controlled, and the rest of the Mid-range tonality is also very good... 5/5 Review by Bad Guy Good Audio Reviews If you're into EDM, Trip Hop, or Hip Hop libraries - This is probably the best set you can get for your money... Period. It literally vibrates in your ear!
