Sleek-Audio has always been pushing the envelope when it comes to in-ear design, and now they have even made a clever way to remove one thing that has always been an issue with in-ears, namely the cable. The Sleek-Audio W1 Wireless Adapter comes as a kit with a transmitter and a receiver which allows you to use it with your current set of Sleek in-ears.
The installation is hassle free due to the fact that Sleek's in-ears all feature the same type of coaxial plugs on the monitor itself. The wireless system is made by a company called Kleer which enables lossless transmission of audio through a wireless connection, unlike Bluetooth which has a negative impact on the sound quality. The Kleer system used has a throughput of approximately 2.4 Mbps which is not a lot, but enough to get the job done.
The Sleek-Audio Wireless system can of course be used with both the original SA6 earphones and the recently launched Custom IEMs from Sleek. You can read those reviews here: Sleek-Audio SA6 Review, Sleek-Audio Custom Earphones Review

"The claim of lossless sound is not 100% correct at least according to the manual, where it states that the sampling rate is only 16 kHz, since the sampling rate of a CD is 44100 Hz or 44.1 kHz." - It seems that there was an error in the Sleek-Audio manual, the sampling rate of the Kleer transmission system is indeed 44.1 kHz or CD quality equivalent. The current revision of the Sleek-Audio manual states 16 kHz, the right value is 44.1 kHz.
Some loss of sound quality is to be expected. Also the fact that it puts an ADC and a DAC in the signal chain will also most likely have a negative effect on the sound quality.
