iBasso - CF01 True Wireless Bluetooth Adapter for MMCX IEMs

A cable-free BT alternative for high quality listening with any of your MMCX IEMs.

In the past, we considered developing a multi-driver True Wireless (TWS) Stereo IEM. But after careful analysis, we moved to a different solution and gave up this idea for the following reasons. To be a quality TWS system, you have to have good drivers and the ability to drive them properly. To have all of this in a small shell with current technology, it is just about impossible. And to incorporate all of this into a small shell, even if you could, the playtime and battery life would be short. Also, when the battery life has ended, replacing the battery could be expensive. To this end, we developed the CableFree 01 (CF01), as a better solution than trying to include everything in a small shell. With its detachable design and better drive ability, the CF01 is a good TWS solution for all iBasso IEMs as well as CIEMs.

For the CF01, we use the Qualcomm QCC3020 TWS chipset, which provides the most up to date TWS features. To this we added a headphone amplifier, knowing this would consume more battery but also providing for a higher-quality listening experience. When compared to other TWS products, our dedicated headphone amplifier allows for a higher current output with higher overall output power. This means the CF01 is able to control and drive IEMs more efficiently with excellent bass and dynamics. In order to maintain playtime, we added a larger battery for each side of the CF01 and supplied a battery-equipped charging case. With the power output and the easily recharged CF01 using the travel case, all of your beloved IEMs can serve you well. You can now use BT with confidence and achieve what you had hoped for when going wireless with excellent sound from most any IEM, be it, ours, another manufactures universal or CIEM. Enjoy the Music!
