Review: molto buone - Certamente un ottimo prodotto per il prezzo di vendita. Suono pulito e arioso, meglio dare un +1 db ai medi e medio alti. attenzione ai gommini, dovete provare quelli che chiudono completamente il condotto uditivo e sentirete bassi, scena sonora e isolmento al massimo ( tradotto potete ascoltare la musica a volume più basso senza subire disturbi ambientali. vale la pena averli. Ps adesso ho anche le mx 880, le jays one+ e le klipsch S4A..... In ordine di resa le prime sono le Klipsch, pio le jays one+, poi le mx 880 e infine queste
Review: Ideal with an ipod. - I love these headphones - they have good sound quality and they don't fall out of your ears every 2 minutes! Are they noise cancelling? Well you can hear outside noises but not above the music in your ear. I use them to listen to my ipod so the volume control is so handy, although it's very sensitive and sometimes you only have to brush up against something and you're suddenly deafened! For me, these are ideal. If you're using them with a phone then I don't know.
