For thirty bucks (price I paid as of a couple weeks ago), these are far and away the best sounding headphones I've ever bought. I've had headphones that cost three and four times as much from labels such as vModa, Koss, Sennheiser, etc., and none sounded any better than these. They have great bass punch without being at all muddy or rumbly, and the rest of the frequency response range sounds great as well. Admittedly the Sennheisers sounded a little crisper overall but didn't have nearly the fullness in the lower frequency range as these have, and they're not even bass-boosted. (For the record, the OneOdio Pro 50 model IS bass-boosted; this is the Pro 10 model and it is not. Trust me, you won't need the bass boost of the Pro 50s; the bass comes through very vibrantly and very cleanly on these Pro 10s.)

The only complaint I have is that the ear cups rotate freely on no fewer than three axes, and it can be maddening trying to get them properly re-oriented when you're putting them on. If I could offer just one suggestion to OneOdio, it would be to PLEASE add just a little resistance to rotation points of the ear cups so they don't flop all over the place.

Any complaints that might have brought this review down to 4 stars are offset by other thoughtful touches, such as:

1) A detachable cord that can be replaced should the cord become faulty (the #1 cause of headphone failure);

2) A 3.5mm input jack on one earpiece and a 1/4" jack on the other so you can use a cord with either size jack;

3) The inclusion of a cord with a 3.5mm plug on one end and a 1/4" plug on the other so that no matter which size output jack your audio device has, you're covered with that one cord;

4) Converting whichever earpiece input jack that's not in use into an output jack so that someone else can plug in (provided their cord plug is whichever size you're not using) and the two users can listen simultaneously.

These phones are so good my wife made me buy her a pair, so now we have two pair. That gave us a chance to test out this simultaneous listening feature with not two but three sets of headphones, and it worked through all three. So it seems like you can chain together as many of these as you have as long as the output signal is strong enough to feed however many are daisy-chained together.

All in all these are some really good-sounding headphones at any price and especially at their current list price, and they have very interesting and thoughtful features per above. An enthusiastic 5 stars as long as they continue to function properly.

I was looking for headphones with a removable cord and I am so glad I came across these.

The sound is lovely. It's really bass-heavy, though, so if you dont like that, you might want to look elsewhere. However, it's not to the point where it's painful or takes away from the sound quality. I keep picking up little bits in songs I never noticed before, which is really nice. And as a reply to the review who said these headphones are Mono; they are not. They are definitely stereo headphones.

The headphones themselves are a bit tight. I have a small head and they are really snug. Which, I personally like as it gives me less background noise but if you have a big head, you might want to look elsewhere. The padding used on the ears are comfortable, though. Not top of the line but definitely better than anything i've had before.

The only issue i've had is, the red cord tends to get fuzzy or only go to one ear if I accidentally touch it or something hits it. However, if I kind of jiggle it around it works fine. Considering it came with two cords, though, I dont see this is a really big downfall as I could just switch to the other cord if this one goes.

Overall, i'm super happy with these headphones.

EDIT: The replacements did arrive and are working fine. Edited the scoring to reflect as such, but I will leave the comment as it originally posted.

These headphones are amazing. Comfortable and sound quality is good.

The reason for the less-than-great rating, however, is the company's help. Both jack connectors are just a little too big; jacks on both sides will fall out occasionally without any force applied to them. I have tried with both the cables provided and some of my own and the problem persists. So I emailed OneOdio and they said that they would replace them, giving them 2-3 weeks shipping due to the holiday season and I assuming weather.

It has been over a month. I sent a follow-up email about how I haven't received the replacement, and it has been radio silence from them. What was once a email-within-24-hours has now become radio silence.

I am using a temporary fix for the headphones so that I would be able to use them. As mention before, the headphones themselves are great. But I wish that I didn't have to try and fix them myself.

Bought these as a Christmas present, but tried them out before wrapping them up to see if they worked and how they felt. These are big enough to cover my entire ear like a cup, instead of resting on the edges of my ear like another pair of headphones I own. And that's a good thing!

I also love the capability to hook up to a second set of headphones for linked listening; I tested that out too, and it works just fine with the aforementioned set of headphones with a standard headphone jack.

It isn't a problem for me, but some people might get frustrated with how much these things can swivel! They swivel from side to side, and from front to back, which can make putting them back in their original position somewhat of a hassle.

Overall, these are great quality headphones!

Beginning with the sound it is spectacular the levels of low and treble that allows you to use it is spectacular, its construction is of very good quality, it comes with two cables of very good aspect and quality. It is a product that gives a very good benefit for its coast.
