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 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!
Without being hyperbolic, I can safely say the CF01 have been my absolute favorite wireless purchase this past year and I'm very fortunate that I was able to buy it through Bloom. Between my wife and children, we have about 15 different sets of TWS to rotate through ranging in price to bargain bin budget up to multi-hundred "sheesh that's a lot of money for a battery that makes noise" flagship territory. None of them give me the same level of satisfaction as the CF01 does. Sure, it doesn't have ANC, HearThrough, or most of the features that flagship TWS have. What they give you instead is a small powerhouse for your IEMs to shine on the go at a significantly lower cost of entry than a DAP. I don't know what magic pixie dust iBasso put inside the CF01, but I have run just about every IEM I own through the set and only a couple seem to stain under the pressure. Each set carries about 80% of what I get from a wired connection and that's great praise. I have to plug guys like the Tin P1 and Dunu DK-3001 Pro into desktop rigs to get better sound quality, so please don't take the 9mW rated power at face value; current delivery more than makes up for it. Combine that with a case that comfortably fits my IEMs with room to spare and plenty of cushioning (that also charges wirelessly) and this option starts to become a no-brainer. The buds connect to my phone the first time every time I pull them from the case, too, which should not be understated. Seriously...I've tried some of the best TWS and they do a pretty good job, but I'd handily trade them in for the day-to-day convenience I get with the CF01. If the only thing you're caring about is sound quality and you already have MMCX IEMs, the CF-01 should be on your short list. Improve the compatibility with a set of OE MMCX/2pin adapters and you may just find yourself rediscovering your IEM collection. Two thumbs up as high as they'll go for these guys (and Bloom). They're fantastic!
