I think this is the lowest price I've ever seen on very highly regarded earbuds. There are some questions on the longevity of these (reports of them failing after a period of time) and some may find them more comfortable than others, but the sound quality is fantastic.

These come with a 5 year warranty, and it's pretty much no questions asked, just request an RMA and tell them what's wrong, they send you a prepaid shipping label, a week after you ship them back, you have a new set. For ease of return, save the box and all packaging.

You may want to do a little experimentation with third party eartips, maybe a triple flanged version if there is a set that fits them.

These have surprisingly great sound, but (like all Monoprice stuff) the build is as cheap as possible. Super cheap plastic clips to put around your ears (optionally). And no good ridge on the earpiece to get a good attachment to, e.g. custom ear inserts (I made custom inserts for mine a few years back ... still not sure how to get them to positively attach to the headphones, though).

Not good for working out.

Not good for swimming.

Not good for looking cool.

Great for audio.

Sound noticeably not as good as Isine10s, but that aren't far off either. They are also easier to EQ with software. The Cipher cable of the Audeze are most of the magic sauce. I dare say I might prefer the M300 to the Isine10s if going without a Cipher cable.. They are similar in overall fit to Audeze.

If the office is relatively quiet, then unfortunately keep moving on.. They are open and they sound open. Not as loud as open-back planars like the HE-560, but loud enough to be a distraction for others.

You most likely will not need custom solutions, but for the price the sound is good enough to warrant that if needed.

The tips can be inter-exchanged between both, but not the clips. The Monoprice are just a millimeter too wide and so they won't attach to the Audeze as well as the Audeze feeling like they are going to break if you put them on the Monoprice. The dimensions of the clips are almost exact as well so if you just want to know if they will perform similarly with fit... yeah, sure.

I replaced the cable on the M300 and use the curve to further secure them over the ear so I actually use the right and left reversed and upside-down to match the angle of the canal the way it was intended.

Unsure if people thought I was talking trash about them because of their continued comparison of the iSine10s and not the LXs, but either way - these are the best value in sound you are going to get other than spending 4 times less for the Sony MH755s for $10-15 if you can get them.

Buy them and then go here: https://www.youtube.com/watch?v=91BUM3WhCfo

EDIT: forgot to mention something relatively important and its accurate to Zs review - the case is nice and looks expensive at a glance and it also, absolutely does not fit the M300. For all intents and purposes, its useless. So you will need another solution to travel with them. I use the M300 at home so I have never bothered finding something that works well for storage unfortunately.

Assuming these are isine 10 knockoffs, if they're on par with them then this is a great price!

They're bulkier than a typical earbud but fit snugly and are supported over the ear. Whether you find that comfortable while working out will be a matter of preference

A very solid no-frill pair, I've been using them about 8 months now mainly for workouts, originally I was worried about the lack of water resistance but I haven't run into any problems yet, this was definitely a great investment.

These compare to the LX not the 10 series.
