Better than wasting money on other expensive headphones.

The wire is excellent. Sound is excellent. Body is excellent. But when you are wearing this headphone and something smashes into it you will hear loud sounds which is disturbing. But not a big issue. I wish it had a mic.

I was hesitant at first since these headphones were so reasonably priced oh heck cheap compared to others I was looking at that were all $100-$300. I'm so glad I bought these,  they work great, sound clear and are comfortable to wear. No brainer, I would buy these again.

I put these on a relatively inexpensive set of earbuds and two things happened: the earbuds became MUCH more comfortable; and, the isolation went WAY up.  I was reluctant to spend this much on a set of tips, but was glad that I did. If you are thinking about springing for a high $$ pair of noise cancelling headphones, try these first.  Recommended.

I am a sound quality snob.  I freely admit this.  I don't expect blow-me-away fidelity from my phone, but I am too easily distracted by the hollow, tinny sound you get from most mobile headsets.  So, I was generally flipping back and forth from a decent set of $40 Sony earbuds for listening to music, and a series of lousy-sounding $40 headsets for taking calls.  After burning through a few of those, I picked these up on the recommendation of the store clerk.  Retail they sell for around $25-30, and certainly sound as good (if not slightly better) than my Sony earbuds and fit snugly and comfortable enough to wear all day.  I intend to pick up a spare set here at this price ($15 at the time of writing this review), because short of a true noise-cancelling headset, this is easily best quality headset I've found the sub $50 price point.

I bought expensive headphones so I can hear good in PUBG. This earphones works well compared to those expensive headphones I bought. I could have saved a lot of money if I only bought this first. Excellent earphones.

Much better than a lot of these iPhone headphones that cost twice as much.  Doesn't sound as good as the Bose MIE2, but cost far less and also blocks out more back ground noise than the Bose.  Could have used a bit larger ear plugs.  But overall decent sounding headphones.

For years, I have spent so much money buying expensive headphones and after trying these, I am asking myself why? In my opinion they outrank the most expense ones out there. I have finally learned my lesson! Expensive is not always best!

Very happy with these headphones.  I reviewed many headphones prior to this purchase.  I even tried on 8 different ones at a local store.
  I chose the DT 770 80 Ohm model and I use a headphone amp.  My primary concern was that my headphones must be closed-back and that they passively mute as much as possible. They are better than the other 7.  The headband is comfortable and not a skull-crusher.  Now, how about the audio quality?  Very impressive.  The bass is ever so slightly "boomy".  The mid-range and high-frequencies are fantastic.  Cymbal crashes are incredible.  I listen to these by streaming Tidal through a DAC and into my headphone amp.  I will also state that I have tried a pair of $4000 Focal phones and while those are incredible - I could not hear a $3800 difference.  Of course, the Focals were better, but, not with my hearing.  I can easily state that the Beyerdynamic DT 770 is WELL worth it.  I like them better than the Audio Tecnica ATH-m50x, better than any Sennheiser, better than any Sony.  For under $200, BUY them.  NOTE: if you buy the 250 ohm model you will need an amp to drive them.

Unlike most of the reviews here, I didn't get these for free or discounted as a 'review copy' or anything. I bought these with my own money and for the most part, I'm really happy with them.

They're comfy on my ears and head. I'm very sensitive and prone to headaches if headphones press to heavily on the top of my head, but these are light enough to not bother me. I don't care for the tall 'cage' looking part of the adjustable headband, but it's worth it for the comfort of the fit.

I haven't had any issues with the lights not working properly, they light up and look cool as expected.

The mic quality, for the price, is pretty amazing. Crisp and clear, not very tinny at all. So many cheap headphones sound like you're talking inside a metal can, but these don't. With a touch of tweaking and cleaning up in an audio program like Audacity, the sound is very very good.

The cord is bulky and thick, and the inline volume adjuster things is freaking huge, so that's something I don't like. But really, for the money these cost, I'm really really pleased. I'd recommend them.

Good sound for reasonably inexpensive headphones.  They are more rugged and seem to hold up well compared to other headphones like Beats that are poorly made and often break.

I have a few expensive pairs of headphones but I came back to these because they are the most comfortable. The other brands are heavier and the ear pieces make my ears hot. The sound quality is excellent. If you do not need heavy bass from your headphones these are well worth a try.

I'm no audiophile nor do I have any earbuds in the $100+ range, but I do have several in the less than $100.  I bought these to replace a pair of Panasonics in the same price range as a disposable set and was surprised at the significant upgrade these were to the Panasonics they were replacing. The six pairs of silicone ear tips made finding a custom fit perfect for my ears and while yes, the cord is heavier than what I'm used to, and can telegraph noise if it rubs across hard surfaces I don't use them typically while doing anything more strenuous than walking (even at a brisk pace, simply wrapping the long cord with a small rubber band and putting the player and bundled cord in a breast pocket, problem solved).

I tried out the 3 different caps and while the cap listed for "Pop music" didn't deliver any noticeable differences, the one for "Jazz" and "Classic" were significantly better than my previous panasonics both for music and digital media content.  I frequently use binaural beats during my daily meditations or when doing demanding article writing, research, etc and found that my alpha, gamma and theta tracks were all delivered to better effect, and the ear tips were comfortable enough that even after 8 hours of use my ears weren't protesting.  Pitting them against a set of Skullcandy and Sennheisers that were 8-11x more expensive and I couldn't tell the difference in sound quality, but again, the caveat being I'm a more casual user of this sort of thing.

Great headphones, couldn't ask for better for the money spent.

I am in search of inexpensive headphones that sound reasonable.  These got good reviews so I gave them a try.  I was not in the least bit disappointed.  They sound better than my $200 ones.  Very light on the ears and do not hurt while watching a movie.

For the price, there isn't much out there that can compete with these. My previous headphones were twice as much, yet only a bit better. Noise cancellation on these is surprisingly good. They can be uncomfortable after a couple hours, but it isn't painful. Just take a break, and you're good to go again.

After trying two other lower priced Bluetooth sport headphones, and wasting money in the process, I found I was looking for with these.

I've owned about a dozen sets of headphones including Sonys, Logitech Ultimate Ears, Sennheisers, and Klipsch Image S4's and X10s.  These are head and shoulders better and they'd better be for an MSRP of $350.  I paid $185 for mine as the price seems to float and I feel they're worth it.

Sound is clear, deep, and well isolated with the oval tips.  High and lows are clear and respond well to equalizer settings in Apple devices, everything from classic rock to modern death metal sounds just as good as over the ear models.  Spoken word in audiobooks and podcasts don't have the harshness I'm used to with cheap headphones.  I've used my dad's Bose earbuds and I still prefer these which feel like half the mass but double the sound.  Watching Netflix on my iPad through these is much better than the iPad's speakers, especially in action movies or heavy soundtracks.

The oval tips are good at blocking outside sound but are fairly smooth so running them up through a jacket causes them to slip from one ear - they more or less sit in your ear canal rather than hold in it.  The default tips are the only ones that work for me, the package has several other sets that are useless to me.  The biggest single issue I have with these headphones - and it's the same with my X10s - is that dry weather and static cause some kind of interference in the wires.  I can "hear" the wires rubbing against a sweater or jacket as I walk, if I tilt my head and they slide across fabric I can feel that static transferred through the wire.  I don't get this on my cheap Sonys I take jogging or the less expensive S4s.  The headphones are also so light they can feel cheap, I do prefer the straight headphone jack rather than the 90 degree curved jack on the X10s and I'm less concerned about the wire bending too much.

People tell me I sound fine throught the mic but it will pick up outside ambient noise easily - that makes using these for calls while you're typing on a mechanical keyboard or something else noisy uncomfortable.  I didn't have that issue as much with a previous cheaper inline mic but I had to shout into it to be heard so that's the tradeoff.

If you're someone like me who places a premium on good audio and is willing to shell out money for good headphones, these are the best ones I've played with that will let you make calls.  Perfect for travelers, subway users, and office dwellers like me looking for a little peace.
