Review on 🎧 Sennheiser PMX 684i Fitness Earbuds: In-Ear Headphones for Workout, Running, and Cycling - Apple Compatible, Sweat and Water Resistant, Neckband Design (Grey/Green) by Pamela Beatty

I find it odd that no one else seems to comment on one feature that brings me back to these headphones - the earbuds are oriented to play sound through the eardrum rather than down the ear canal. This alignment is very difficult to find in headphones/earbuds. If you google "in-ear headphones" and "hearing loss" you'll find tons of articles that when using non-noise-cancelling earphones we tend to turn up the volume to hear, but a high volume aimed directly at the ear canal transmitted, can damage internal auditory canal. ear and cause permanent hearing loss. Instead, they send sound waves through the ear because they are in the ear canal and the speaker is at a 90 degree angle to the eardrum. But judging by the reviews, it sounds good.
