I have actually had these for 2 years and they still work completely. I'm so impressed by the top quality of these headphones for the price. I have actually utilized them on countless flights, physical fitness strolls, tanning sessions, home cleansing sprees and more. I've sweated on, splashed and dropped these earphones a number of times with no issue. The only issue I have actually had is when I'm tanning on the roof covering of my apartment building, occasionally the wind will certainly blow tough and impact the audio. So if you're intending to use these outside above ground height usually, possibly look somewhere else? lol but other than that they have actually executed far better than expected. The sound canceling feature works so well and I like that there's a choice to remove that function while still paying attention to your sound. The very best thing about these headphones is the battery power! I've had them for 2 years and I have actually billed them a handful of times, and I make use of these on a regular basis. The battery power is unmatched!If you're trying to find top quality headphones for an excellent rate, these are for you!
