Sometimes it is nice for a product to focus on its main feature and forgo the need to add a bunch of attractive extras. Then, rather than forcing in the features you maybe will not use, can the manufacturer focus on the quality and present it at a lower price. The RevoNext appears to be doing exactly that. Certainly, there is a variant with inbuilt calling and the like, however, this set is pure audio and at a cheaper price.
