## Description

Upgraded Monster Boomerang Neck Speaker Bluetooth Wireless

Review: Great sound, a little dorky but who cares! - Easy peasy. Set up was just bluetooth connection to my phone, took about 10 seconds. Long lasting battery, really simple operation. Good crisp balanced sound quality. Great alternative for ear buds, I'm a bike rider and this allows me to hear what's going on around me especially with all the stealthy electric cars that sneak up on you. Being that it's around your neck you do end up sharing you playlists with anybody near. Lightweight, compact, well made. quick charge.
Review: No More Ear Pain - Excellent product, I detest any thing in my ears, none fit they are always to big and to uncomfortable, I have tried ear buds and head phones, this neck Bluetooth is awesome, the weight takes some getting used too, but it’s well worth it. I haven’t tried wearing them in bed yet, but I will one day. Easy to use and charge. The cost is well worth the convenience, and sound is great. So if you are looking for a a perfect fit you are in the right place . Thank you

## Questions & Answers

**Q: Is there a way to disable welcome and goodbye sounds everytime the device connects/disconnect?**
A: It's pretty annoying and that sound is too loud makes it impossible to use in the office, maybe I have to return mine.

**Q: Is the mic any good for calling ?**
A: So I've found hacks for these speakers, put the microphone closer but not be able to blow air in the microphone hole, and also I put one side of the speaker up either by hand or shoulder when I really need to pay attention to what I'm trying to hear, very clear, clean sound music and talk, long battery, have a good one

**Q: Can you wear this while sleeping?**
A: I wear it around the front of my neck as I sleep mostly on my back. It is perfect. I can even roll onto my side with no problem.

**Q: When you turn it on or off etc, is there a voice yelling at you like it does in many other Chinese speakers? If so, can you turn it off?**
A: It does let you know you are connected or it says goodbye when turning off not yelling at all these are nice wearable speakers

### ⭐⭐⭐⭐ Great sound
*by D***S on September 8, 2024*

Let's start by clearing up a few misconceptions. These speakers do not somehow magically create a "bubble" around you where only you can hear the music. On the contrary, others can hear the speakers, and you can hear other sounds. (In fact, other sounds, if loud enough, can completely drown out the speakers' output; automobile traffic, when you're walking along a street, is a good example.) Thus you probably won't use this thing outdoors, in public, or in an office, or any sort of shared space. So what is it good for? It's good for absolutely terrific sound, beautifully presented to your ears. There is something about the positioning of the speakers, in the neckbone area, that constructs a superb stereo "stage", making the sound brilliantly clear and three-dimensional. I don't think there is any "bone conduction" going on here (though you certainly might feel some vibration of the speakers through your bones); the sound is coming into your ears. But it's coming in with sparkling clarity and ease. Without anything inserted into the ears (earbuds) or covering the ears (earphones), you "just hear" the sound, vividly and easily. I use this device with my iPad for watching movies and with my iPhone for listening to classical music, and it is just terrific. The button controls are okay; after a while you get used to them. The order of the buttons is a bit odd — pairing, on/off, volume down, volume up — why isn't on/off first? But you soon internalize it. Pairing is very easy; typically the most recently used sound source and the speakers "remember" one another, and to switch sources you just hold down the pairing button until the voice says "Discovering" and then pick out the speakers in the Bluetooth panel on your sound source. The voice that greets you on startup, shutdown, Bluetooth discovering, and Bluetooth connection, is way too loud, as other reviews have rightly pointed out. The charging port is atrocious, difficult to access, buried very deep in a restricted cavity. Many of my charging cords can't get in there at all. The device does not announce its charge level on startup, which is a major flaw.
