I'm a truck driver I own a headset that cost me 150. And it dies within 2 days. The comfort is low the audio quality is low the only good thing it has was the mic. But these are made out of cheap plastic and they are 30$. I don't understand how they last longer are more comfortable and sound better than my 150$ headset. The are light and don't fall out of my ears like every headphones I've bought. Even expensive ones don't hold a candle to these. The quality and sound is loud enough to match a old 18wheeler full throttle. They just don't die... a whole day and only 90%. The only down sides is the material is cheap feeling and looking and the mic isn't as good. But still they hold up super well. I really wanted a reason to say these are bad. But even it's negatives are positives because of the cheap material they are super light. Really good on the noise cancelation. The range is a little lower but even so that's after getting behind a box truck that's 80ft long and all wood and metal. They don't fall out and I move alot even when jumping in and out of the truck and trailer. Yea these are definitely worth the 30$ probably the best 30% you'll spend for a long long time. This is after one week I'll reupdate it in another 1 to 3 months. But so far amazing blew past what I expected.
