I guess its a chance we take when ordering online. They lack the precision of the AKG studio phones I like best but the sound quality allied with a perfectly black soundstage make them sound better than they are. i would NEVER buy this product. I ordered these shoes for my wedding. They cut in and out all the time which is very annoying. And as an added benefit, theyre much quieter! Thinking of having 5 on the top because of height. There is no charging port on protective case so you have to charge airpods outside of case but for me it?s not that big of a deal. I love the bag so much that im gona keep it even though it looks very wierd, Ill put a picture, but overall for bikers as i said its a nice back rack and will suit your needs with the ibera bag that clicks right on. Da una casa così seria mi sarei aspettato che la sezione di cavo dal mic al jack fosse staccabile e quindi facilmente sostituibile.
