Compared with headphones and in-ear headphones, headphones will do less harm to the ears. But I suggest you control the time when you wear headphones, because some people will feel pinched when they wear headphones for a long time.
In addition, if you personally prefer in-ear headphones, I suggest you choose one that fits your ear shape. If your ear canal is small, I suggest you choose small ear canal headphones, or some headphones with soft materials.
Here I recommend two kinds of headphones, one is a headset and the other is an in-ear headset.
Head-mounted:
Wuconglin
The earmuffs of this earphone are made of protein skin imported from Korea and high-density inert cotton from Taiwan Province Province, which is particularly breathable, while the head beam and the outer side of the earmuffs are made of polyurethane. This earphone is very comfortable to wear, does not oppress the ear, and does little harm to the ear.
In-ear:
Wu Pandora
This earphone is designed from the perspective of women. Its size is 1/3 of that of ordinary headphones, and its material is skin-friendly silicone. Even if you wear it for a long time or lie on your side, it will not cause discomfort to the ear canal and outer auricle.
