SpinFit was founded in 2009 to create innovative new technology for eartips. Their flagship design allows silicone tips to more easily swivel to create a better seal, and direct the sound more accurately in your ear canal. They have a large range of eartips designed to provide the best fit for a large number of IEMs and earphones.
