This was perfect and exactly what I needed to keep my lenses clean. Me compré estos auriculares hace poco más de un mes, los utilizo casi a diario y para el precio que tienen son perfectos. However, the only negative is that the band that goes around the ankle is a little too big. Sounds alright but they dont stay on very well. These fit very well and feel solidly made. Sturdy but a bit difficult to install If it?s in stock, buy it. Good sound, great fit, supplied with multiple sizes of ear plug (I have small ears and struggle with fit for in ear headphones), clear calls, good battery life, excellent appearance and feel. Just got these today and these are super lightweight- just like my adidas cloudfoam. Important to read the reviews for the best fit.
