Good afternoon everyone - I'm really glad I found this place and this thread as these are the exact same questions I've been wrestling with! I, too, am in the market for a BT IEM. The primary purpose would be for commuting, running outside, and work-out at the gym. After much research I've narrowed it down to a 5 options, but they all have their downsides;
1. Jabra Elite Sport: mediocre SQ, big in the ear and can get uncomfortable
2. Jaybird Run: possible connectivity issues (not sure if this has been totally rectified)
3. Bose Soundsport Free: Big (like really big), and no noise isolation, meaning gym or commuting could be a hassle
4. B&O Beoplay E8: Possibly not sweat resistant, debatable SQ?
5. Bragi The Dash Pro: Expensive...apparently the SQ can be anything from 'the best' to 'the worst' depending on who you ask. I find this one the hardest to find out anything about...does anyone have any insight into the 'Dash Pro' iteration?
I can't say that I'm a 'learned' audiophile, but I do have a keen ear and love my music (mostly rock and classical) and find that poor speakers/headphones/ear buds can totally ruin my listening experience. Maybe I'm just picky.
Cheers and thanks from the frozen North!
