Practically perfect

Sending in a lightweight package but really good product to recommend especially compared earphones supplied by the manufacturer of the smartphone (Apple in my case). The sound is excellent. Works with Iphone 4 and 5, I tried both.
Three sizes of tips allow a real insulation and a very good comfort, excellent for the train or subway for example.
Only slight inconvenience the on / off control on the earphone cable does not allow volume control that allows the equivalent of the original Apple headphones.
