Wearing headphones everywhere and at any time has its pros and cons. On the one hand, headphones provide better sound quality than any traditional audio output device. Noise-canceling headphones block all unwanted noise and distractions to allow you to focus on the tasks at hand. Wearing a headset relieves you of the tension and stress. 

On the other hand, wearing headphones for long periods can cause skin problems such as acne and contact dermatitis. Headphones can cancel your communication with the environment. Therefor headphones can increase isolation. The better isolation your headphones provide, the clearer and more accurate the sound quality will be. While it implies that a set of headphones reduces all outside noise by that level, that’s not the case: headphones don’t attenuate all noise frequencies equally, because their acoustic isolation properties will be frequency dependent. Additionally, listening to music at high volumes for extended periods can cause permanent hearing loss. It is important to be aware of safe sound levels and when to take a break from headphones. 

The CDC has detailed information on various daily experiences and the volume, or decibel (dB) level, associated with them. One of the important things to note when considering headphone use is that personal listening devices are tuned to a maximum volume of around 105 to 110 dB. For reference, exposure to sound levels above 85 dB (equal to a lawnmower or leaf blower) can cause possible ear damage with exposure of more than two hours, while exposure to sound of 105 to 110 dB can cause damage in five minutes. Sound less than 70 dB is unlikely to cause any significant damage to the ears. 

But note: Wearing headphones as a design of your t-shirt or fashion top has absolutely no unwanted side-effects! It just highly amaze and surprise your friends.
