Saw this thread while browsing today. Before I give a final recommendation, how much of your workout is high-impact stuff like box jumps or sprints versus just lifting? It makes a difference for the fit because some buds handle vertical movement better than others. Honestly, if you sweat heavily, you definitely want to avoid over-ear models. The ear pads soak up moisture and they will slide right off your head during squats. You should look for an IPX4 rating at minimum. That rating means they are tested to handle sweat and splashes. The Sony WF-C700N Truly Wireless Noise Canceling Earbuds are a really solid mid-range option that usually cost way less than your 180 dollar limit. They are light and have a decent grip. If security is the main goal, maybe look at the Sony Float Run Off-Ear Headphones. They have a hook design that goes over the ear, so they wont fall off even if youre dripping sweat.

Quick question tho, you running on treadmills or outdoors? I love the Sony WI-C100 Wireless In-ear Headphones because that neckband prevents floor drops, plus they're way under your $180 budget!

Ive tried many pairs over the years, and big headphones just trap way too much heat. I always recommend the Sony LinkBuds S Noise Canceling Earbuds IPX4 because they only weigh 4.8 grams. In my experience, that lighter weight is key for keeping them in during heavy squats. The IPX4 rating is technically enough for heavy sweat. Pick them up for about 150 bucks and youll be set.
