I'm trying to say:
My brother does not use headphones and earpieces because he finds them uncomfortable.
And the basic sentence structure I have in mind is:
兄は (reason) からヘッドフォンやイヤフォンを使わない。
But I'm not sure how to phrase the "finds them uncomfortable" part as I'm not sure what word/phrase can express this correctly. I found words like 気{き}詰{づ}まり, 気{き}味{み}悪{わる}い etc in the dictionary but they all seem to deal with the emotional aspect of comfort, such as feeling safe, calm etc. I'm looking for words that refer to physical discomfort, in this context, because headphones are too heavy, stuffy, bulky etc.
Can those words be also used for describing this physical discomfort, or are there better words to express this situation?
