Awei ES10 : less than $4 (http://www.gearbest.com/earphones/pp_144726.html) Bassy and warm earbuds, with a good amount of details and a fairly large soundstage.
The one that come with a smarphone, most people don't use it so if a family member buy a new phone ask then to give you the ear buds.
I have not listened to it yet, but just ordered two pairs: TY Hi-Z HP-32 Apparently the maker is a friend of Lee from Venture Electronic. I read a comparison the other day between the original Monk and the TY Hi-Z HP-32 and that person prefered the TY Hi-Z HP-32 by far. The name does seem to be a negative thing. "Monk" is so much easier to remember. I have tried some cheap ones but ended up trading, selling or giving them away. Except for Monk and Monk+. Now I have started to prefer Monk+ to the original Monk and I'm curious about how the TY Hi-Z HP-32 can compete against the Monk+...
Golov posted a link to the comparison in the earbuds thread. Thanks to Golov I spent more money yesterday! (well, only $15.80 in total for 2 pairs...)
I've only seen it from Penon audio. It's $1 more expensive if you order from their home page than if you order from their page on Ali express. I still ordered from their home page since you can pay with Paypal there. I had to pay $15.80 instead of $13.80 for 2 pairs including shipping. I think I can survive paying $2 extra...
I prefer the TY HI-Z 32 to the Monk+ slightly better bass and more transparency. At under four dollars the Plextone X41m are hard to beat for good bass and detailed treble
I have just received my SHE3800 and OOTB I am very impressed. I shall use them for a few days and then post a comparison with Monk+ and Hi-Z 32 on here.
