These are surprisingly good budget true wireless earphones which work well with stable wireless connection and feel well built. Set up is simple and even technophobes should be fine setting these up and using them. With budget products it is important to have realistic expectations. As well as the actual transducers wireless earphones need batteries, amplifier/DAC and the wireless modules in each earphone, and there is an additional battery in the charging case. That's a lot of stuff for £30 and so don't expect full on top of the line audio but they should work. And these do work, very well. Tuning is a bit bass heavy for me but that is typical of most products in this category, the tuning is the classic V and although detail and definition are not class leading the sound is very listenable and more than adequate for casual use, commuting as use as a daily beater. For the price you can do a lot worse and sound quality is pretty similar to most budget wired earphones. I must admit I'm paranoid about true wireless earphones falling out and getting lost and prefer wired or neckband types, but the market clearly prefers true wireless and these are a very good product for the price. Recommended.
