I recently bought a pair of Kleer wireless earphones and have been just blown away with their quality. I have in the past used some bluetooth earbuds and was used to their relatively poor sound quality. Kleer is a new wireless protocol and was designed to improve on bluetooth, which was not designed for quality sound reproduction.
The only downside is the price. The company that developed and licenses Kleer must require a hefty payment for its use, as all the products that use this wireless technology are pricey. I paid hundreds of dollars for my earbuds and there are a few other choices I could have made that were even more expensive. Since I have a few sets of earphones in the past, that is my biggest worry – that I will lose them and my investment. It is really easy, since I travel a lot, to misplace things that are not tied down. I would really be bummed if I lost these earbuds since their sound reproduction is so great!
