Turns out that although I do love Bluetooth headphones, the form factor I prefer to use depends on what and where I'm going to be while using the headphones.
While I'm walking, at work on-site, or commuting, I prefer in-ear headphones. I prefer in-ear headphones while doing so, mainly because they are light, the sound quality is good enough, and more comfortable to wear while while I'm on the move.
Meanwhile, when I'm at my home office, café, or bar, I go for over-ear headphones. Mainly because they are better at isolating me for ambient noise, and thus help be better concentrate on what I'm doing, or just better shield myself from the ambient noise.
Currently I own a pair of in-ear and a pair of over-ear headphones. One pair of over-ear headphones is stationed at my home office, while the other comes with me in my backpack when I go on the road or just want to work somewhere outside other than my home office, or my desk at work.
When working at my desk at work, I've a pair of in-ear headphones living there for when I want to focus on a certain task or just not listen to the chatter of the clients or coworkers talking among themselves while not cutting myself from them if I'm needed. Another pair lives at my pocket, so it always comes with me on my walks or commute. Specially because, when on my way to, or from work, or walking, is when I've time to listen to the podcasts I like, or I just put some relaxing music.
At the end of the day, Bluetooth headphone have won me over.
