I use heavily earphones. They usually last between 3 and 9 months because of the fucking wire. When I am working I cannot type comfortable because of the wire, it is in the middle. When I move I always pull the wire. If I am walking with my mobile in my pocket I also pull the wire from time to time. So they always broke in the connector because of the wire. Even with a lot of care they always break in the same place. So it is around 15€ every 6 months. You can buy them cheaper but the sound is crap. My Bluetooth headset was 30€ and have been working like charm for more than 3 years now. They have 8 hours of battery life and I need to charge them less than the smartphone. So I don't get the inconvenience of charging something than last more than an smartphone.
