I love headphones especially at work they be super load and I can tune my coworkers out lol.
I know what you mean, also known as earspeakers, earphones or cans i do the same, do you have overhead speakers? or noice cancelling ones?
I have the noise cancelling ones from Beats by Dr. Dre they was a Christmas gift they definitely gets the job done. 
They are so good! no wonder beats electronics is a subsidiary of Apple  inc. everything related with apple is top quality
Yes they are over priced which everything from Apple is lol but it is well worth it last a long time and it has a high volume as well. 
Yes thats the thing about Iphones, the entire line of smartphones are overpriced
The chargers is even overpriced you will pay $30 just for a new one and the earphones that come with the phone are $50 and up they are making a good amount of money off customers. 
Thats why i prefer andriod OS, they are able to run apps just like iphones do
I have a android to and I love it same emojis, games everything and our headphones are cheaper lol.
You really are a headphones fan! you need to try the brand BOSE, they produce for consumers, aviation annd military, top quality too
