These headphones were provided to me free of charge by the company but the following review and comments are all my own.Ordering, shipping and packaging: The ordering process was relatively straight forward, shipping was provided via Prime, so one day. The headphones arrived in a very clean, compact cardboard package. The package is visually on par with a lot of the high end brands; hi-res pictures and brand logos compliment the clean layout. You are provided with the earphones, three pairs of additional ear tips (S,M,L), a lapel clip for clipping the earphones to your shirt/jacket etc, some booklets and a headphone jack cover made of plastic.Built quality: The headphones themselves are all metal and are very solid with a nice heft to them, I don't have any fear of these being crushed or broken by any day to day usage. The phones have "L" and "R" labels directly on the earpieces so you won't confuse which is which. The cable is bright red, covered with a standard nylon wrap and it's got a good feel to it. Would have been nice to see it wrapped in a braided cover but that's just my personal preference. There is an audio control piece connected to the right earpiece with three buttons for play/pause and volume up and down. There's also a microphone for phone calls. The buttons themselves have a nice tactile feel to them when pressed but they are very close together and the same height, so for someone like me with big fingers, finding and using the controls was not the most user friendly, probably one of the only big negatives about the headphones.Sound quality: The specifications on the box say the frequency range is 100Hz-20KHz and I'm sure that's a typo as these things have very good bass response. I would venture to say there was an extra zero added to the low end frequency specification which would have these headphones going from 10Hz-20KHz and that would make more sense. Interestingly there isn't a port on the earpieces (that I could find) that allows for slightly deeper bass, most higher end headphones usually have these but it didn't make a difference with these as the bass wasn't an issue. I played a huge variety of music, movies, Dolby Atmos demos and video games with these headphones for the past 10 days, including hi-resolution audio files (24/96 FLAC and DSD64). The overall sound quality is excellent and I'd have to say that they punch well above their price class even at the current price of $16.95. I have a pair of $100 earphones (in-ear) from a very popular brand and several pair of standard earphones that were provided with my various Samsung smart phones and these Marsno earphones are now my go-to because they sound better that the other headphones I have in my collection. The thing that stuck out other than the bass was the imaging; they have very good stereo imaging with a smooth and clear sound that is rounded off by the good bass response. The $100 headphones are very treble heavy (too much when an external amp is added to the mix) and the bass is less that what these Marsno headphones provide, probably due in part to the larger size driver (10mm vs 8mm). The Dolby Atmos demos I played were impressive as I heard the sounds coming from all around me through the headphones. As mentioned above, I have a portable external headphone amp/DAC that adds some extra oomph while on the go. The amp adds a nice push to these headphones without overpowering them and the overall sound is enhanced that much more. Sound isolation is on par with most other non-noise cancelling in-ear headphones, meaning not much at all but these headphones can go loud enough that it's a non issue in all but the most noisiest of places.These headphones are highly recommended even at the retail price of $59.99 but at the going rate they are probably one of the steals of the year for headphones. You will not be disappointed with these at all and I'd advise you to get a pair now.

I previously bought the Marsno M1's; they had great sound but their design made them uncomfortable over time because their weight tended to dig the hard metal housings into my ears. When I saw that Marsno was making a set with an ergonomic design, I had to try it. These M2 headphones have the same great sound quality and good comfort too!The response is very good across the entire sound spectrum, but the bass is particularly noteworthy. I can hear frequencies down to nearly 20Hz, and these headphones can feel like they shake my head! That doesn't make them bad for classical music though: I listen to that a lot and it sounds great. The strong bass makes videos and movies sound better too. Due to great clarity, I sometimes even hear new things in music that cheaper headphones or speakers don't reproduce.These headphones do not have active noise cancellation, but they do a pretty good job of blocking out any external sounds when inserted, especially with aftermarket memory foam tips.Improvements over the M1:* Much better comfort due to ergonomic shape* Volume control as well as play/pause buttonAreas for improvement:* Volume controls feel cheaper than on the M1; the M1 has a single play/pause button that feels very sturdy but the M2 uses a single piece of plastic to cover all 3 buttons and its in-line control set has less metal in it. (The one I got differed from the pictures too; it might be an older or newer design.)* The M2 uses cloth to cover the speakers to keep junk out; the M1 uses sturdier (but more open) perforated metal disks* More eartips would have been nice: the M2 came with 6 sets (S/M/L long and short) so I was hoping that the M1 would as well, but it comes only with S/M/L. (Not a big deal: replacement tips are cheap and easy to find and you can upgrade to memory foam tips.)Notes:* Comes with nice fabric carrying bag and different sizes of eartips* If you are sensitive to weight or hard metal housings you might want to try the much-lighter Panasonic ErgoFit earbuds: those provide even better comfort for extended listening periods. Even the ergonomic M2 headphones can get a little heavy due to their metal construction.* The (well-constructed) cable does transmit some noise to your ears if bumped or tapped; this isn't a big deal but can catch you unawares* You might wish to play with an equalizer a bit depending on what you're listening to or watching; the strong bass can occasionally make low sounds (like explosions) too loudBOTTOM LINE:If you are looking for great sound at a great price, try these out. They sound as good as, or better than, much more expensive headphones. (For instance, I think they sound about as good as Apple's AirPods, which I listened to briefly but did not find comfortable.)
