I've recently owned the SE846 before selling it and moving on to the Fitear TG 334! Granted, these impressions are from memory and I was using different cables with both earphones (TWcu on the SE846 and TWau reference on the SE334, although I did try the stock cables, but only fleetingly), so take them with a pinch of salt. Sources used was my iphone 5s, with music ripped at 320kps to 16bits/44.1kbps.
The first thing I must comment on is the lows of the SE846, I think what Shure has done with the lows of the SE846 is nothing short of a miracle, and in my opinion, trumps that of the Fitear TG334 in terms of quality, depth and oomph. The bass of the SE846 to me, is well-rounded and punchy, and hit very low indeed. Bass is also well controlled, with fairly slow decay, yet maintains a lot of its detail. Despite this though, I never experienced any bass bleed into the midrange. I think this stands as testament to the quality of the low pass filter that Shure has implemented. However, I find that because of the quantity of the bass, my ears tended to get a little fatigued after extended listening. YMMV. The bass of the Fitear TG 334 are just a touch more than what I'd consider to be neutral. It can hit low when called on, and it can pack a punch where the music calls for it. The detail and texture of the bass is amazing, and I don't find it as fatiguing as that on the SE846
As for the mids, I find that although both have very lush mids, I tend to prefer the presentation of the TG334! It feels more intimate, and sounds more upfront. Vocals are absolutely heavenly on the TG334. I also tend to perceive more detail on the TG334, which may stem from the bass volume on the SE846 clouding out some of the detail on the mids.
I find that the SE846 has more laid back trebles than the TG334, resulting in a somewhat darker sound. Both are detailed and articulate, but I find the TG 334 has that bit more sparkle which lends life to the trebles, resulting in a signature I prefer.
All said and done, I think I have no regrets selling out on the SE846 and buying the TG334.
Thanks for the detailed comparison!
I actually picked up a secondhand pair of SE846s today at a price where I can happily on-sell if I decide I want to go straight on to the TG334s, or I can save some more $$ and end up with both
Everything you've said sounds spot on to me in terms of the intimacy, detail and amazing overall presentation of the TG334s. I'm liking the SE846s a lot, but I'm yet to have that "wow" moment with them that I experienced almost instantly with the 334s. I am definitely loving the bass on the 846s and the way it is perfectly balanced with the music, but only time will tell if it becomes fatiguing.
I seem to recall from my short demo with the TG334s that the bass was emphasised in the lower mid-bass area to create that awesome sense of punch when needed. Does that ever get over-bearing with any genres? I'm coming from UM Miracles which I find great because they have quick, punchy bass with just the right amount of body when it's needed.
