No one speaker can produce all sounds well. Luckily these can split those duties amongst 5 speakers per ear. 3 BA's for the highs, 2 DD for the lows.

Detachable 2 pin connector allows you to make them bluethooth

Really wish they came with foam tips, but you can find replacement tips of the appropriate diameter elsewhere

I decided to try these on sale. Definitely impressed with the sound after putting on some 4.5mm foam tips from amazon. $7
Was hoping that they would block out more interior car engine noise while driving. The acoustic noise blocking doesn't seem to change much, I was hoping for more of an iem on stage kind of experience. It blocks enough that sometimes its hard to hear someone talking softly from a few feet away. I would say a 15db cut is generous. In quiet studio environments these are very nice. For the price, these are amazing performers. For a portable synth jam in the forest, this is an amazing product. You can hear every detail. They perform even better when you sort out the correct fit with the after market tips. Well designed and worth the money.

I never realized the clarity of IEMs compared to traditional earphones, I can hear notes that I never realized existed in the songs I like!

Regular earphones (you know the traditional wired/wireless in war phones like Beats, Air Pods, Skull Candy etc etc) have a single speaker that has to do all the work (lows, mids, highs) these have 5 speakers inside!

I paired the Quintents with the Soundblaster Super X Fi mini amplifier and the Quintents ($49) beat what I thought were my high quality earphones by Sennheiser ($199 for earphones, what was I thinking) in terms of clarity across all bands. How can $49 earphones perform better than a brand name like Sennheiser? It all comes back to having multiple speakers I believe, each having their own job.

The quintet IEMs are definitely an upgrade from my standard off the shelf headphones and earbuds. Would buy again should anything happen to these.

I got to use them five times before I misplaced them. After I put memory foam tips on them. I really got to hear the musical detail of the bass.

I use these for monitors while playing drums during rehearsal and live shows. They work great for that purpose.

I purchased these in ear wired headphone for running purposes only but after a short burn in, I discovered that these inexpensive headphones were too excellent in sound quality for use a running headphones but would be used as my reference headphones. The highs are crisp and clear. The mids have meat on the the bones but very clear and articulate. The bass is quick and hits very low. Overall and excellent buy, job well done MONOPRICE.

Christmas present for my boyfriend. He loves them and uses them all the time for work conferences and music while he works out. He likes that he can take them out of his ears but still leave them in place because of the over-ear design. He takes advantage of the microphone functionality frequently.

It was good even as my first pair of in ears

Great they are very comfortable to wear. I use them on stage as in ear monitors. They work great for me.
