This part is what I'm trying to get you to avoid. You can spend years and thousands of dollars chasing something that better amplification will fix. You have two great entry-level pairs and will get far more out of improving the source than you will chasing the speakers. GIGO is a real thing.
It's also why DAPs aren't dead yet. Really hard to beat just plugging your headphones into a well-amped source. Unfortunately, there are no TWS dongles I know of to date that would be capable of giving either pair enough current to be comparable with wired performance, either. Just be prepared for the compromise.
Comes down to what you're looking to get out of them. What sort of versatility are you looking for? I could throw out a blanket recommendation, but want to make sure you're happy with what you end up with. Some answers to these questions will help:
- What will you primarily be listening to?
- How much time will be spent on calls vs listening to music?
- What equipment are you using as a source?
The EA75t are probably my favorite Jabra sound signature, but not for every genre. Bassheads will love it, but you sacrifice a good amount of detail for that fun. That may not matter to you.
I've personally found the Noble Falcon 1 (with a little EQ) to be a better all-rounder if you're genre-agnostic like me.
If call quality dominates all, though, Jabra hands down.
