## Questions & Answers

**Q: What version is this? I have noticed there are two different versions being sold.**
A: 2 Gold in the middle is standard size and 2 gold tips is smaller version.  I had the smaller version and I sent it back because I did not like the way my music sounded on it.

**Q: Could this stay in place while running?**
A: Not likely - it’s a loose fit - maybe light running but I doubt it - I only walk with it and I do love it it for that purpose.

**Q: Does this connect to desktops? I can’t seem to connect via Bluetooth or cable**
A: I am connected to my iPhone via Bluetooth . I don’t think that a desktop computer has Bluetooth. And l know the petite doesn’t have cable connectivity.

**Q: Is this water proof?  Could it be worn on a pool to do water arorbics?**
A: No

### ⭐⭐⭐⭐⭐ Easy to pair, decent sound quality, not bad for bit more immersion
*by R***2 on 20 July 2022*

First thing I will say about these is that they are essentially speakers on your neck so people around you will hear what you are listening to. That being said, I usually like to use these at home for gaming and music. I do not have to use my speakers and I can walk away from my computer and still be able to hear the music or video playing through these. I have liked most monster products so I decided to try these out as I wanted to use my speakers less to try and save some power. First I will talk about the material. I was very in love with how it feels. It is a silicone feel at the back of the neck but it does fit for my neck comfortably. It is more front heavy as that is where the hardware mostly is. The speakers are protected pretty well to reduce interference while also being solid so you do not have to worry about it being easily punctured. Dust and hard can build up on it but it is easy to brush off. The headphone cannot really be adjusted too much even with the back piece being flexible but it fits for the most part. The controls are on the right side (if you are wearing it). In order to control the sound you need to press + or - while changing tracks you would need to press and circle button twice or three times to depending on the direction you want to change the track. Pairing is pretty simple to just press and hold the play button until it flashes and then you just find the device on you device and connect. The buttons feel solid and have a nice click to them. For the most part, the instructions are pretty clear in helping and simple to follow. It also charged by type c and there is a small flap at the underside of the headset in order to plug in the cable. It can be a bit challenging to open the plug as the material stays put pretty well. The overall sound quality is pretty nice. Be aware that since you do not have this in your ear people will be able to hear your music. On to the microphone on this headset. For the most part, it was actually really clear and I could talk on the phone while walking or answer my calls in the car without having any issues. This thing does not irritate the skin but again this is front heavy. The tips are not magnetize so they do not stick together (I thought they did but they just come together do the weight). This product overall is a good buy if you are okay with playing your music and such out loud. I think it really helps in immersion into VR or gaming. Be warned this is only water resistant and should NOT be taken into swimming and such. The battery life lasted me up to 5 hours before I need to recharge the device. It does vary based on connection and how loud you are playing the music. Only thing I will say about this is that it is front heavy so it puts a bit of pressure on the back of your neck and the metal in the front is prone to scratching. Other than that great sound, clear microphone, good immersion.
