Excellent sound quality, balanced with great bass, mids and highs but terrible in ear fit.

As I bought it on a sale, the cost benefit ($35) for me was excellent. The sound quality surprised me, Great bass, mids and highs, very balanced. But the in ear fits is terrible, you need to adjust it back on the ear all the time, even trying all the buds sizes. I wouldnt pay the original price of $99, I believe theres other best options.

Update:
After breaking them in for a few months, these now sit comfortably and still sound excellent. If you get a pair, I'd recommend finding a head-sized object and leaving these headphones on them for at least a few days to stretch them out. If you can make it past the head-vice stage, these are really excellent headphones.

These sound excellent, with especially excellent bass. Well-defined, tight, and balanced. However, they grip your head like a vice and get extremely uncomfortable very quickly. This effect is intensified tenfold when wearing glasses or chewing. I don't have an especially big head (at least I think I don't), and these still give me a headache within a few minutes.

If you want to know what they feel like, apply slight pressure to your jawbone at the exact spot where it meets with your earlobe, and hold for a minute.

The fit, finish and packaging of these earbuds are exceptional. The sound is perfectly ballanced and the build quality is top notch; I'm thoroughly impressed!

So why the 3 star review? Because no matter what foam/rubber adaptor size I tried, I couldn't find a comfortable fit. The metal speaker section that pushes into the canal is large, rigid and ends up pressing on the soft tissue within my ear. Wearing for more that 15 minutes gives me an earache.

It's unfortunate because, in most other respects, these are the perfect set of buds. If you have larger, straighter ear canals, these would be an excellent choice.

Quality wise these headphones are good. They give out a decent sound and for a good amount of time on a single charge. However, they are too big in the ears and frequently come out of them. The batteries are placed in the earbuds which seems to be the problem. If the batteries were somewhere else along the wire and the size of the earbuds was small, it would have scored 5 stars

The sound quality is very balanced, highs are very clear, yet not overly piercing. The bass is very defined, and has a good amount of force, but I would not recommend it for people who love powerful bass. The mids are not drowned out, they are clear and enjoyable. They are very "fun" headphones in that they have great sound for any genre of music, and gaming as well. In FPS titles, I found that the highs help greatly with locating footsteps and such, while the bass is good for larger sounds like explosions. They are not 7.1, but I didn't find that to be an issue, since most gaming headsets have bad sound quality and surround sound implementation. They are open back, so the separation is better than traditional closed back headphones because there is more space for sound to travel. I love the velour material on the ear cups, definitely better than faux leather. It is made from plastic, so it feels light and not rigid. I suspect this is due to the manufacturer cutting corners to ensure superior sound quality. The main problem with these is the sound leakage (it is a side effect of all open ear headphones, not a manufacturing issue). If you are going to wear these crowded places, do yourself a favor and pick up the SR950's. They are very similar, but they are closed back, so they have a smaller soundstage.

Pros:
-Clear, balanced sound profile (no EQ tweaking needed unless for minor problems with certain setups).
-Very comfortable, can be worn for hours without hurting or getting too hot.
-High quality-to-price ratio.
-Good for any genre of music.
-Large soundstage
-Long, thick cable that is less likely to break.

Cons:
-Plastic construction (feels a bit on the cheap side).
-Leaks so much that you can use them as desktop speakers if you turn them up loud enough (not joking).

Sound is excellent, but I will not trade it with comfort.
Can't fit my head, maybe my head is too big but Sennheiser fits really good.
The right unit is defective, but I think it is probably rare for others.

First of all, these headphones offer excellent sound quality and very good noise cancelling capabilities -- equal to that of Bose, in my opinion.

My issue with these headphones was comfort.  After wearing these headphones for 3 consecutive hours, I was continually having to adjust them b/c they were so tight.  Also, the earcups are relatively small and, if you have larger-than-average ears, you're not going to like these.  They're not nearly as comfortable (or as lightweight) as the Bose QC2s, in my opinion.

I sent these back and ordered some Etymotic Research earphones.  Hopefully they'll be more comfortable.  I'm just trying to avoid spending $300 on Bose headphones.

I am enjoying the clear sound quality & clear easy usage of these headphones. The only problem I have is the fit isn't perfect.

No matter how I put them on they can't seem to fit right but that's a personal issue. Bass is decently present and volume is on the low side even with an equalizer present but quality is more what they aimed for over how loud. Feels like they will stay in my ears but if I can get them to fit comfortably in my ear I would enjoy them better.

I have had these for about six months, once they are seated correctly the sound quality is phenomenal. Outside noise is isolated as good as it can be for an in-ear model, bass is clear and distinct, mids are there, highs aren't too bright

Be careful with how far in you put them. In order to get the best sound they need to go in FAR. The problem is if you have larger ear canals, and they go in too far, the rubber tip can become stuck in your ear canal. In my case the seal was too tight and when I removed the earbud by pulling on it (not the wire) the rubber tip was still lodged in my ear canal.  I had to go to the hospital and have it removed by a specialist!

This is the best pair of earphones I have ever used, hands-down. The sound quality is incredible, the bass is just unreal, best bass I've ever experienced. Highly recommended for sound quality.

I dropped one star because the fit of the earbuds was uncomfortable. It comes with 3 pairs of those rubber things so you can pick the best fit for your ear canal, but switching them out didn't seem to help me much as the actual devices the rubber things attached to are, in my opinion, a very strange shape that makes it painful to wear them for more than an hour or two.

However, that said, the slight discomfort is worth it for the incredible eargasm from the sound itself, and it's also possible that my ears are just a weird shape for it.

[EARBUD ORIENTATION & FIT] Rating (Out of five stars): 
These earbuds weren't the best fit for me. My ear holes are pretty small and while these have three different sizes there wasn't one that fit me perfectly. Getting the earbud in your ear well is ideal for optimal sound quality. If I held them I could tell these have better sound quality than I was able to experience. The earbud pads are just too big for me. I had an extra pair of conch earbud pads (B014FTSXQ4) that fit these so I swapped these out with those and they fit perfectly now. I like that these are labeled left and right. The orientation is easy to differentiate.

[SOUND QUALITY] Rating (Out of five stars): 
The sound quality is better than expected. The audio is rich and focused. The vocals are clear with no distortion or echoing. The sound quality has perfect clarity and grip.

[BASS] Rating (Out of five stars): 
The bass quality differs from song to song. A bass rich song will have seismic bass while the others songs have the bass blending in with the rest of the audio. The bass rich songs display the bass in these earbuds the best, if you like bass you can feel, then you will like these. The bass doesn't cause the earbuds to crack, which is a plus.

[NOISE CANCELLING] Rating (Out of five stars): 
The noise cancelling is on par with other earbuds. The louder you play music the better these are at noise cancelling. When I wear these while I'm working I can't hear myself typing on my keyboard. When I wear these while I workout I can here some sounds around me, but nothing significant. I can hear my kids playing when they get too loud. Overall, the noise cancelling is fine for me.

[CONTROLS] Rating (Out of five stars): 
I really prefer inline controls. I'm not going to lie, I won't even use these controls. I will just use my phone to change the volume, skip songs, etc. The power button does kind of annoy me. I guess I'm impatient but it takes forever to turn these on and even longer to hold it down long enough to get it to pair. That being said once it's paired I've not had to re-pair them. If these had inline control and a more responsive power button I'd be happy. The controls are functional, just not my style.

[SUMMARY] Overall Rating (Out of five stars): 23 out 25 Stars *4.6* Star Average : 
In summary, once I replaced the earbud pads with my own, these fit great. The sound and bass quality meet all of my expectations. The noise cancelling is exactly as it should be for earbuds. Pairing is easy. The Bluetooth has good range. They stay paired in between uses. They have long battery life. (I use 5 times a week for a total of about 4-5 hours a week. I charge once a week.) My only pet peeve with these is that I prefer inline control.

Great sound quality, but the design is just obnoxious.  Doubly so if you wear glasses or want to wear sunglasses.  The over the ear style is just uncomfortable and no amount of bending or twisting will actually get them to stay in a shape that holds on to your outer ear.  Also, no amount of pushing, pulling, twisting or interchanging the tips will provide a snug fit in your ear canal.

But, if your ears are just the right shape, or you somehow manage to get a good seal in your ear canal, you get some pretty good sound quality.

I have developed issues with ear irritation with these-  which is unfortunate  because I find the sound quality to be fabulous.  Enough bass for me, and fantastically clear sound.  Highly recommended if you can deal with the fit.

sound quality is good but fitment is a huge issue. The actual plastic piece that goes in your ear is way too big so even with the smallest eartips it still didn't fit in my ear. Kinda disappointed because I cant use these at all now.

I tried all size combinations and could not get a fit that felt like it was right. They are comfortable but it takes some adjusting to get right amount of sound.  If you do not place them just right, volume is lower.  When you do get it right, they sound great. I plan on returning.

Not an headphone audiophile, but the sound quality of the buds are above average in my experience, especially for the price (got them on a lightning sale).  Definitely a fan of the look and style of these, and the packaging and amount of different sized tips were also a nice touch.

My main complaint is with the fit.  I have gotten really used to the earbud design that specifically fits a left or right ear, and no matter which tip I tried I couldn't get a comfortable fit where these stayed in. High marks for quality and presentation by the manufacturer and I would have loved to use them as my daily buds, but they'll stay tucked away for emergencies as I wear out the $8-$9 Panasonics.
