I love these wireless earbuds! Spund quality its good. Son realmente espectaculares y han sobrepasado mis expectativas. Its so quiet I feel like they are broken or something. I have a pair for slipping on to potter around the garden and a pair for indoors instead of slippers. I also didnt like that the cheaper $250 RT-81 that did come with a pre-amp came with the old AT-95E needle instead of the new VM95E that is more upgradable without remounting the cartridge and the motor didnt have a sensor monitoring speed. Unfortunately if you test it then it?s no longer exchangeable for Amazon and it?s third party sellers. I have a 2017 Kia Sorento and even adjusted to the shortest length it is to long to fit on the back half of my luggage rails. The only downside I?d say is the mic is a bit rough to move up and down, it should be a little smoother. I actually do like the angled wrist rest.
