The earbuds and the Bluetooth work perfectly. No issue on that. The sound quality is okay as it's not a mid-tier IEM so no surprises there.
My only (and frustrating) issue with this IEM is that the accompanying eartips are really bad. They often stuck in my ears because they don't stay with the earbuds. Could potentially be a safety hazard. I have never had earbuds that eartips could stuck in my ears despite changing all the sizes available. Poor QC all around.
I got these on promo sale, along with the complimentary wireless adapter that I haven't used yet, and overall the earbuds got a build and sound quality that I can't complain about.
I primarily use these for listening music when i'm commuting or catching up on podcasts whenever I'm doing chores around the house. Using the bigger tip that they come with, it fits nicely into my ear, and i don't really have a fear of these slipping out.
I've tried taking calls on these, but it's practically impossible, as the person on the line couldn't understand what i was saying. They said I sounded faint, and whatever else I was doing at the moment was too loud for them to understand me.
The bluetooth connectivity is a bit wanting, since it will cut out if there's a single wall between the earbuds and the phone. But if you don't need anything fancy, this is the pair to go with (given that you can also get them on sale?).
The fit is comfortable enough to use them for more than an hour or two. And they are incredibly light.
Great piece of engineering. Cannot match any studio monitor headset but for the price and ease of use those are just excellent.
Alpha&Delta Fit are realy fit - they're very comfy in my ears. Eartips could be better, but for start it's ok.
Small charging station and good battery life (over 4h on one charge).
Great BT connection stabillity. You need 10m and several walls to cut off the signal.
Sound? It's decent - warm, bassy, with slight emphasis on vocals. I would be happier if A&D Fit were less dark, but most people can live with it. Lack of better BT codecs.
For promo price, very nice TWS earphones. For full price? You can take them if you don't expect great sound quality.
