Amazing
Though I have one complaint, I'm still giving the headphones 5 stars due to their excellence in fidelity. I am astonished. The bass response is felt in your feet, from the upright to the short - scale to the fretless Jazz Bass and the Rickenbacker and its wide dynamic range. On the other end of the spectrum, the highs come through bright and clear as you feel your eardrums get warm from the friction of the vibes. Phil Collins' cymbals from 1970's era Genesis are crystal. Ok, time for the bummer. One of the cables that come with them (one has a built-in microphone, the other does not, and this is the one about which I am writing) is way too short. Yes, the longer the higher the resistance, etc., but c'mon. I require more than a meter/m.5 to do my DAW work properly, especially when I use them while playing guitars - why wouldn't I use them with that? These probably have the very best fidelity I've heard, and I say probably because maybe I have listened to more responsive headphones though I don't remember makes/models if that is so. Final verdict. Get these.

Best headphones I have ever owned!
I'll start by saying I am not an audiophile. I bought these headphones based on the great reviews, of which this is another one. All of the good things the reviewers said are true. The sound is incredible. I hear things in songs that I never heard / noticed before as if I am truly hearing it for the first time. I find myself wanting to get to the next song to experience what new things I will hear. I notice the mix of the song and the placement of the instruments in the soundscape. It is quite amazing. The over ear headphones fit my ears perfectly and are very comfortable wearing for long periods of time. I love the detachable cord so it can be easily replaced if damaged. The headphones are solid and well built and feel like they will last. These headphones are well worth the cost and I will be using them exclusively for serious music listening from now on.

Love these headphones, great sound stage!
I was just trying to find a comfortable set of wired headphones with a decent microphone for my work laptop when I saw these on sale and decided to give them a go...and I am so happy that I did! These have taken the place of my Bose QuietComfort 35II when listening to music, which I thoroughly enjoy, but they lack the expansive sound stage and deep bass that the ov21's are able to convey. I really like the sound of these and they are very comfortable. I found that I can also listen for hours without my ears getting fatigued, and they were a great buy to boot!

Very Nice
Phones look classy and you get a great sound out of them too. Can be used for mixing or casual listening. If you want a cost-efficient hard case for them, they fit snugly into the LLTGEM "Headphone Headset Case Compatible with JBL, Beats, Sony, Soundcore Anker etc. et al."

Solid In-ears!
Iv'e had Thinksound in-ears for a while now. The TS-02's, Rain 3's, the On1's, On2's, and the OV 21's. So yes, I am a fan of Thinksound. Aaron sent me the TS 02's while I was deployed to Afghanistan in 2013 when I started looking for a replacement set when my other set shorted out on the right side. Aaron, thanks again. When Thinksound came back, I put the In 20's on pre-order right away. They look and sound like the Rains, but slightly retuned. Just a little cleaner and just a touch more bass. And they are small and light. Once they are in, I almost forget they are in except I'm isolated form the outside world. The do a good job with passive sound isolating. Very good for my music library, worth it! Aaron, if you read this, tried to review the OV 21's on here and Amazon block me, only verifed purchases.

Wanted to like them
I returned this item (in20 WIRED IN-EARS) as I believe it was broken or had a defect, because the midbass frequencies were way, way, way too prominent. It nearly gave me a headache. It's a shame as there was some really nice clarity in the upper mids and treble that I wasn't expecting. I really wanted to like these, but the midbass was way out of whack. I bought the ov 21 Headphones when I purchased the in20's, and am listening to them as I type this. I have had them for over a year now. I like them. They are comfortable, and do a pretty good job blocking out surrounding noises. No issues with build quality. The wooden backs on the earcups are nice. Good clean bass that doesn't muddy up the midrange. Lots of treble energy, but never painfully so. I'd consider it a V shaped sound, but the mids are never lost. I like the detail they present. I never feel claustrophobic with the soundstage. I wouldn't use them for mastering or studio work, but enjoy them for listening to music.

Simplify your search- read this!!
I returned two other sets of headphones before finding these. If you want a traditional pair of earbuds but with really good noise reduction (no noise cancellation setting) but I use them in the gym where they blast crappy music and on medium volume iPhone/spotify I literally can only hear my music. The sound quality is excellent as well, if your an audiophile weirdo idk but for the average person very very good, goes more than loud enough with a strong but balanced bass. I will buy these as long as they make them no question.

Decent, But Not Worth The Price
Decent enough sound, but not for the price. I ended up returning them and bought two pairs of Vibes 202 Wired Earbuds as they sounded MUCH better for half the price.
