I personally dislike wearing isolated earphones for longer periods of time since they short-circuit the ear canal and I hear every bone in my jaw area and neck after some point.

3rd generation Airpods, while don't isolate, sound pretty epic for what they are. When sitting at home, I can listen to some music and genuinely enjoy it, and I like their non-isolating nature because it helps me to hear traffic around while walking with them. The only problem is, talking on the phone with them might get a little noisy for the other party, but I believe phone hardware filters some of it.

When compared to their rivals, they really have higher resolution, and enjoyable sound balance. Also, iPhone scans your ears with FaceID camera to profile them, so they are also tuned for your ears from get go. This makes positional audio really shine, too.

The original iPod buds were pretty flat and tinny. I used to use a pair Sennheisers (I don't remember the model but they were pretty high end) to be able to enjoy what iPods had to offer, back in the day.
