Advanced M4 in-Ear Earphones Headphones with Mic/Controller, Tangle-Free Cable, Natural and Balanced Sound

I bought these on April 8th, 2018. Since then, the right ear bud separated into 2 pieces. I don't know if they're a press-fit assembly, but the only way to reassemble it was to use super glue. Today (11/09/18), I was taking them out of my ears and the left ear bud separated into 2 pieces. It also, broke the connection, so I will have to try and fish out the wires and solder them to the terminals and then glue the 2 halves together. For the $40 price tag, I am not impressed.12/01/18 Edit. I contacted Advanced and filed a warranty claim. They provided a pre-paid shipping label and I returned my ear buds for inspection. A week or so later, I received an email telling me that they had determined that the glue holding the can into the socket had failed and that they had decided to replace the earbuds. The new earbuds arrived today in the standard retail package. Thank you ADVANCED.Review went from 2 stars to 4 stars because I appreciate that they stand behind their products and have good customer service.

they sound very balanced, yet warm. If you change from comply to rubber tip, you gain a bit of the highs and more bass, and these are quite accurate since if the recording of a song used a sibilant microphone for the artist, it may sound harsh since they are quite accurate, like Kendrick Lamar's album "good kid maad city", and every song has sizzling highs because of what i suspect is the microphone they used for recording him rap.Bottomline: They should be worth more than they are, but you simply cannot beat this at a bargain price of $40

I needed a pair of utility IEMs and these hit the price point I had in mind. They sounded fairly awful out of the box but I burned them for 3 days and they improved noticeably. I did have to change to a bigger Comply tip for a better seal. I was hoping the new tips might attenuate the high end a little bit, but not so far. I am hoping this improves over time, because even though I like extended highs, I find these to be just a bit harsh. I might also experiment with other tips to see if that helps. These come with a nice selection and a very nice little carrying case. The only real serious negative is the cord, which is nicely made and looks strong, has a high microphonic noise level. But for $40, these are a good buy.

I am no audiophile. I just was in the market for headphones that would allow me to listen to my audio books and music on the train without having to turn the volume all the way up. These fit the bill. They are truly life-changing. I was surprised at how affordable these are. I feel like you definitely get your money's worth out of these.Update 7/3/18- The left ear phone had disconnected/broken off,so I was only able to listen with one earphone. I messaged Advanced and they gave me instructions and sent out a new pair of head phones. I am definitely pleased with the excellent customer service since the headphones themselves are great.

- tanglefree m4 cable hasslefree for user.- heavier than usual cable reduces microphonics.- not a bassy type of earphone. Focused on low mids. Good with treble and vocal (no overly sharp sounding)- doesn't totally block out the environment noise especially on flight. But the comply foam tips did help in that area. You can still enjoy the music better than many other earphones in the market.- would be great to have another spare set of comply foam tip as spare.- overall, this set is value for money.

Came in a well-packaged box. Includes a variety of ear bud tips, as well as a professional-looking case. Sound quality is on par with that of a device in the $80+ range. Sleek and kink/tangle free design. Nicely designed overall.

Love it! Well built, great sound for the pride. Will buy another as a spare

so far very good. much lighter than i expected so it's like air on my ears. great sound and clear calls. I'm enjoying it. JG
