Installation literally takes a few seconds and its got a great design that can fit nearly any phone. I love the longevity of the battery life for traveling! I am delighted with this splitter! But as you wear them it gets flatter and now they are quite loose. 3 sets a night, 225 nights a year. I just wanted to say that you will not regret it and you will doubt that you will be receiving 5 pairs of earbuds and you will be receiving 5 pairs of awesome earbuds that you can easily pay 5for 10 times as much for 1 pair of these let alone 5. Apparently the ?chairmans? are smaller than the ?country club driver?! So just be aware these shoes seem to be a shoe or slipper that needs to be worn occassionally not all the time around the house like house slippers. Battery life is long. I ordered anyway, unbeknownst to me this item was coming from USA and was incurring a customs charge on £18.
