Product Manuals

Q: Are the headphones durable? How long did they last you?

A: I bought a set in January, they lasted just about 3 months. Thought I'd been too rough with them so bought another pair. They too lasted three months. These things are crap. Do yourself a favor, don't buy them.

Q: How good is the noise cancellation and base?

A: I had a root canal and used these and it deff help not hear the drilling

Q: What is the wire length?

A: About 5 ft

Q: Do these headphones have a microphone?

A: Yes! The Headphones have an "In-line Microphone," which "lets you enjoy hands-free calls." The "Sound" quality is excellent! I'm very pleased with this purchase!

Q: I just got these earbuds and on the package, it says voice command? What does that mean? Also, what does the button do? The package also says that you can pause and skip songs. How do you do that?

A: With your phone awake, you can hold down the button and activate the phone assistant (Bixby, Google, or whatever). You know the "Hey Google" option? You can just hold the button on the earbuds to activate it, and then start asking the question. I only use YouTube music so I don't know about the other music apps, but I assume other music apps have similar button functions. Pushing the button once, pauses the song. Pushing the button twice (fast) skips to the next song. Pushing the button three time (fast) goes to the previous song. . My suggestion is to, basically, play with the button, e.i: go to different apps and try pressing the button, holding the button, and pressing the button two or three times. Make the most use of the earbuds. They're simple, but very useful. Especially if you listen to music in bed, like me. Instead of reaching over and unlocking my phone to skip to the next song, I just push the button on my earbuds to skip or go back.

Q: Are these compatible with the PlayStation 4's controller headset jack?

A: I can confirm these work with ps4 controller headset jack. I bought a pair and everything works great, both sound quality and mic. I tried with both the original ps4 controller and the updated version and they both work fine. I have an original ps4 but I doubt it would matter if you have a ps4 slim or pro. The headphones are compatible with the 3.5mm jack on the controller and that’s all that should matter.

Q: Do these headphones have the piece that can move up and down to keep the wires from getting tangled? It can move up and down from about half way up the cord until it reaches the earpieces?

A: Hi Kris, yes, it can only reach up to the unit's microphone/multi-function button. Additionally, this unit comes with a wire manager to avoid its wires from being tangled.

  • Rated 5 out of 5 stars

    Great product.

    I am very happy with the headphones. The sound quality is very good for listening to music, talking on the phone or watching movies on the laptop. They fit perfectly because it includes different sizes of adapters. A small piece of silicone is attached to adapt the length of the cable as well. There is no volume control but for its price it is a good product. I recommend it if you are a classic like me and you still like wired headphones.

    Good wired Earbuds even w/ Apple adapter!

    Better than I thought, wanted some corded earbuds because I kept losing all my Bluetooth earbuds. The quality even connected to an Apple dongle 3.5 to Lightning sound amazing!
