Both of them have impressive bass, with a slight edge in quality (not quantity) going to the t1e. The mids on the edse are more forward and musical. The mids really take a huge step forward in comparison to the t1e. Some will like it and some won't. I really like the ss of the edse for acoustic, live recordings, alternative, rock and Symphony Orchestra. T1e is more balanced. Treble quality goes to the edse, with a touch more quantity to the edse. The t1e is a more balanced signature that is easier to have long listening sessions with. The edse is also great for long listening sessions but I can see some people not liking the forward midrange. I personally love it.
Build quality goes to the edse with one exception. The edse has an awesome high quality cable, good strain reliefs, an L shaped plug, and heavy duty metal housings. It's beautifully built. The only advantage the t1e has over it is the cable cinch.
New posts are coming in that members are getting t1e without bass. Idk what to make of this. If it was me I would definitely send them back for an exchange, because my t1e have plenty of bass and sound amazing.
T1e has a better tuning for playing every genre of music. It makes everything it plays sound like it was tuned for it. Edse is good at every genre, but some genres just sound a bit better because of the forward mids.
T1e
Both are a winner IMHO. You can't go wrong with either one.
T1e is $35ish dollars or so.
Edse is $15ish dollars or so.
Both are fantastic.
