Instructions werent extremely helpful at some steps. Luckily, we found this great set. Material degrades and gets sticky. but they are post gym sandals, so they’ll do for that. I ran them off a Yamaha AV receiver that had a decent headphone output and it really brought down the highs to acceptable levels. Sure enough it would give me yellow or red ! Love how soft the material is. Adidas como siempre, calidad y comodidad, excelentes sandalias, a mi pequeña le encantaron y el color perfecto para ella, volveré a comprar. Overall I would recommend these for anyone looking for affordable, good sound, noise canceling Bluetooth earbuds. Also heads up make sure if you have the slim take the adapter out and put it on the PlayStation first then put it in the fan i struggled with this at first didn’t want to break it.
