Hybrids are the best ;)... Get the best of both worlds :P
On a more serious note, Dannybai thank you very much. You were right about these (you are one of the very few I trust honestly). Even out of the box I am really enjoying them. I was really worried about these being fart-cannons like the FX700s were. The bass does hit hard and there is a lot of it. But it is in balance with the mids and treble. Even at reasonable to slightly higher volumes. While on the FX700 just tapping it a bit and the bass would steal the entire show. Much better. I look forward to hearing them improve with break-in.
Update: The timbre is what I really missed on the FX700. Due to things being noticeably more balanced I can really enjoy that woody timbre. It's the best timbre I've heard on any IEM honestly. So natural. The drums/instruments in general sound so real. Vocals are beautiful. Are these really gonna get better with usage? lmao. Another huge plus for me is the longer cable. The short cable on the FX700 was so annoying. Plus putting on the adapter cable compromised its sound... I listened to some bass heavy tracks and the 850s handled it like a champ.
I would say 100 hours is a must for these to show their true sound. The open box sound is not as tight as my pair. Bass becomes way more dynamic, tighter and more controlled. Mids solidifies, highs become one of the best if not the best..You think the timbre sounds good now wait till the sound tightens up. Not to mention the definition of overall sound improves.
I have well over 200 hours on my pair and I can't comprehend how good these earphones sound to me. It is on a level I never expected.
Don't care if any of you guys that read this don't do burn in..Burn them in, do it in secret.. It gets better and better..
