Interesting how polarized the comments on these are. I bought them about a year ago and unfortunately I have to call a Neil Young on these (" ... it was a piece of crap!"). Really light and comfortable, great fit but sound is poor. Treble is harsh and tinny and overall they sound like they have a piece of chewing gum stuck in the nozzles. Respectfully disagree with those saying they punch above their weight. IMO, even in the sub-$25 range there are others that sound considerably better than this ( e.g. KZ). If you want something just for podcasts or audiobooks or hands-free phone calls (the mic is good) these would be fine -- but not for music. Pity, because the fit and comfort really are excellent.

Just how advanced are these? Do they have VTEC?

I wonder how many people will ever get these references XD

God, these sound awful One of the worst IEMs I’ve heard. Way too much bass, finicky fit, and everything sounds like it’s coming from the other side of a brick wall

TheOmegaCarrotHello OmegaCarrot, if you are getting the bass response, you must be getting the proper seal. It is possible that the particular pair you received may not be functioning well. Can you let me know the type of IEM's you prefer to understand your sound signature preference, to see whether the unit may be malfunctioning? Please send an email to so our CS team may guide you through (RMA if needed). -Peter

What size should I use on these for the T series of Comply's foam tips? Can't seem to find anything on the internet about it.... The s2000's aren't listed on comply's website either

MattyChongIf I had to guess, I'd say the nozzles are 4mm in diameter, but you should contact Advanced Sound, so you know for sure.

MattyChongT-500 would be a good fit for S2000.

Just received these. Usually a new IEM or headphone takes awhile to get used to, but these immediately made a very good impression.
First of all, the shape is great. Pretty close to perfect. Very, very thin for an over-ear and very light. They don't quite "disappear" (nothing does) but they aren't that far off. Can definitely use these in bed and lay down on your ear.
As a guy with small ears, I really appreciate the moldable ear guides.
The sound is pretty spectacular, especially for the price. Saying that these can compete with $200 IEMs might, if anything, be an understatement. These things hit way, way above their price point, and if it's any indication I don't experience too much of a shock jumping from balanced HD-800s with $2500 worth of gear to these driven through a One Plus One. They're fairly energetic, but also somewhat (somewhat being the operative word) neutral. Fairly analytical but free of sibilance. Mids are slightly recessed and bass is moderately boosted and could be a bit tighter, but that's to be expected. Well above average, but not great soundstage and seperation.
One interesting attribute I've found is that isolation is very poor. For some people this may be a good thing, but for most it will not be. They're also a bit fatiguing. But for $20, these are pretty easy compromises to make.

hurleybirdI agree with your appraisal. I found that these work best with comply foam tips as the fit is a bit finicky and the treble is a bit forward. I don't usually put Comply foams on because I find that they soften the bass, warm the sound, and remove treble detail. However, these need some of those effects. I think it was a shame that they include Comply in their other IEMs but didn't here. Missed opportunity. All-in-all, excellent sounding IEMs with a very detailed approach and punching well over their price bracket for sound quality.
hurleybirdI'd say I agree with the majority of your assessment. These are the best $20 IEMs I've heard by far, but given that I've yet to hear $200 IEMs I can't agree or disagree with the comparison. For me these are non-fatiguing, luckily.

Despite having a hard time getting a proper fit, these aren’t half bad!

Happily picking up 2 more of these, 1 as a spare and 1 for a gift.
One thing I will say is, as a person who really hates straight plugs, this 4-pole 6cm angled extension has saved this product's main flaw for me:
If anyone has any questions that I didn't answer in my previous message 4 weeks ago, let me know.

The exact same response curve as 95% of budget chinese IEM's...

I too had to do exactly the same thing as you did because I had the same problem. The tips sat so shallowly in my ears that I couldn't get a decent seal with any of the included tips and nothing from my collection either. Ended up doing the same as you. Sacrificed a small tip to create a spacing ring. Wish I'd have read your comment before I spent a bunch of time on figuring out a solution myself.
Listening to this and Monks side by side makes me feel like I paid an extra $10 to get a set of Monks that actually fits in my ears. It sounds better, but that might just be because it fits better. Weirdly, they compare best to my $20 over-ear Sennheiser 201s (which I've always thought was a steal; Amazon confirms this, as they are currently listed for $36.) Similarly detailed (which is to say not very, by my standards,) similarly a little boomy for my tastes, similarly extremely comfortable. Fortunately, I bought them as cheap travel earbuds, not budget sonic heaven, so "decent but unremarkable" is just fine with me.

I got these on a previous drop, really impressed with the sound quality on them. I highly recommend these.

These earphones are absolutely awesome sounding. I've paid 5x the price for earphones that don't even equal these but..... the Jack is a couple mm shorter. I compared it with my stock ak's that came with my s8 and because of this they don't stay seated. Be aware
