Honestly, I'm a little pissed off. Not because these are bad, but because the 40x doesn't get enough credit for being one of the top best studio headphones to date. The majority of the people choose its bigger sister, the M50x, which don't get me wrong, the M50x is also a great studio headphone, heck, just the M series are great sets of studio headphones, but reason saying these dominate the rest really is that these cans will be the closest to neutral quality when monitoring your music. The thing with the M50x is that they added an extra cable and "more color" to their sound by dosing up the treble and bass a little bit. And I'm not just saying this one dominates the rest of its sisters because of its best neutrality, it dominates ALL STUDIO HEADPHONES. Don't believe me? No thanks to SoundSensePro, their YouTube videos can prove it to you.Now of course there might be a few exceptions with some other top-end audiophile headphones that are great for monitoring, but most of them are expensive and they require amps to get the same studio quality, where you could just get these, no amps required for good neutrality, all around $100. These have a nice build quality, nice comfort to the ears, although it could be better in my opinion because it takes some adjustment ever once a while and feels a little tight, otherwise I can listen to these for hours, and surprisingly these have great noise isolation, but I mostly will be talking about the main purpose of why these cans are great, which is the sound you get from them.I have been to several sound boards and monitor music with a variety of different studio headphones (Sony MDR7506, Sennheiser HD 280 Sennheiser HD 650, etc.), and ever since I picked up these headphones I know this is going to be my main source from here on out.Here's the thing with studio headphones: the goal is to make them as neutral as possible (not flat. There is a difference between flat and neutral sound) so you know that you're picking up the same exact audio from its main source. Now because bass is very common nowadays, most studio companies think that in order to get a flatter sound, the more bass you need to take away from it so it doesn't "eat-up" the mids and the highs. This doesn't mean you can't hear the lows, it's still rather noticeable, but the issue is you're not getting an idea of how much bass is being applied to the audio, and you need that. These headphones not only monitor bass (and it's just the right amount of bass to monitor as well. You don't want too much bass or too little), but you get to monitor with a great soundstage performance on the M40x. Now another good headphone I encountered in a recording studio is the old Audio Technica ATH-M40 f/s, which took an hour for me to compare the difference between those and the M40x because they were that close. The only difference I could pick out of them is the M40x is more enhanced with its soundstage and stronger noise isolation, still making these a whole lot better.These are worth every buck if you are looking for best neutral sound. Only thing I would say to be aware of is its portability and durability. It only comes with a handbag if you want to bring it around, the headphones are bigger than they appear, and even though it has great build quality, most of it is made of plastic, so if you are a DJ and want to bring them wherever you go, just don't be surprised if they break. These are more for staying at your home or sitting in a recording studio for listening than going place-to-place constantly. Will keep you guys updated when I start experiencing trouble-issues.

These are my all time favorite headphones and I've recommended them to several people.I love them so much, in fact, that when I show up to work without them, I am lost. I now have a pair at home, at work and a spare for when I've misplaced one of those. These are so affordable, that on the off chance I do put them out of my reach for more than a few seconds and I lose one, I don't blink an eye when replacing them.Helpful tips-Change out the ear pieces that come with it originally. I've had friends purchase these and complain that they hurt their ears, but opting for a smaller piece was perfect for me. My ears do hurt on occasion, but I wear these headphones for 8+ hours a day and i'm not surprised by that.Phone calls-These are fantastic for my needs on the phone. I never have anyone complain about the quality whenever I'm utilizing them around the house or in my office at work. However, if there is a a lot of noise, like in a restaurant or outside in the wind, there may be some issues.Noise cancelling-There are times when I'm working but dont want any music in the background but also need to focus. I'm distracted by any faint sound I may hear in the distance and am easily side tracked. I will frequently wear these in my ears just as ear plugs alone.

For the price these are a great deal the sound is clear good miss and highs and great bass. These are not audiophile level but they're really good.

The best smart earphones I ever purchased. When I starting talking it mutes and when I stop talking it plays again. Hands free. Great sound, clear, loud, and crisp.

Sound quality super , Noise cancellation andBass quality best

Super LOUD. can hear everything without it even being on my head. Great sound quality and comfy fit. I wish I had 7 of these lol this is the true definition of price doesn’t always match quality. You get better than most for half the price!

I can use this all day nonstop and not have to charge it

I've ordered these twice, since I lost my original pair that lasted me a year with no issues. Absolutely the easiest, cheapest, and best wireless buds I've used. Sound quality is great, they give you like 6 different sizes of attachments to fit your ear snugly, and they NEVER come out unless you tear them out during activities. I use them when I ride my motorcycle as they fit perfectly under my helmet and never come loose. They are also SUPER loud so make sure to turn your volume down lol, as it blocks the noise of my bike and you can hear the music clearly on the interstate. I highly recommend these!
