Just want to talk about my experience a little bit, because it's been terrible to be honest.
I sold all my good universal IEMs after ordering the Encore. First mistake! They took longer to arrive than I was told it would. That was in May. One of the main reasons for choosing Encore over, say, K10, was the quick turnaround time but... Read on.
More importantly, I got my Encore back recently and I think, finally, everything is okay. That's 4 months after sending in impressions (work next day delivery!). In that time I was only able to use them for about 20 hours and they were always either being repaired or pending repair. They don't seem to care about this at all--even an acknowledgement and apology would have been nice.
The first time the sockets were too recessed (inaccessible) and then one unit failed within a couple of weeks.
The second time, the little white wax guards in the sound tubes were displaced and seemed to block the sound tubes. Had to pay to send them back.
The third time I found some other stray little filter like part in a sound tube and had a small fit issue with one unit. And a sound tube/bore wasn't fully open like the others.
Altogether that's 4 months, and I'm in the UK, where they're headquartered. Each repair took 2 or 3 weeks and I also had to wait to schedule appointments. That's a third of the warranty period gone before I'm even using them!
By any standard, this is terrible. For the price point, it's very bad. Compared to what I read about Westone treating someone with multiple problems on a comparable model (sent him a universal W50 to keep), it's even worse.
The people at ACS are nice to deal with, especially before you buy. However, their post-repair communication is basically non-existent. I always got mine back with a note that said warranty repair but no other details.
The sound in general is really good at times but very badly suited to some genres. Low frequencies sound distorted at times and highs in some genres lack airiness. Soundstage is average. In short, female voice and classical can be very bad. But they're fantastic with harsher music, like metal.
Build quality is very poor in my experience, obviously.
Fit is good and isolation is good too. I'm not sure if silicone is actually better at isolation than acrylic, but it seems more comfortable.
The Revivo is a great idea but it has an annoying beeping low battery warning that has woken me up in the middle of the night a couple of times. The only way to turn it off is by opening it, but that exposes the desiccant.
The cable has pros and cons. It's wonderfully low profile, but it's very bad with its memory retention and tangles easily if not carefully stored.
I hardly need to say that overall, it's probably the worst personal audio related experience I've had, and given the price point, it's very disappointing.
