## Description

Upgraded Monster Boomerang Neck Speaker Bluetooth Wireless

Review: Great sound and easy to use - Love my boomerang...I started riding my bike...Needed some music...Headphones, cords, phone falling on the ground!!!!...No cords, connect via Bluetooth to my phone in a few seconds...Simple, easy to use controls on the side...Fast charging...The sound quality is excellent...No music blasting right in your ear...I like that I can hear music but also the areas around me when riding my bike...I also use it with my smart TV, makes music and movies, so much better...
Review: Great sound! Nice and loud and gives a good experience. - I'm using this to connect to my tv in the evening when I want to listen to tv without using the regular speakers and need it to be a bit quieter so I can hear my elderly father who's in the living room area. My mom currently has a BOSE wearable sound bar that goes around the neck that is three times as expensive, so for this review I'll compare the two. The one thing that stood out is that this neck band connected to the tv easily and was way louder than the BOSE band. Read the directions as you have to hold the button for a certain amount of time and it prompts you and tells you the blue tooth is on. I think just went to the tv settings and had it search for speakers and just click to pair and we were good to go. My mom's speaker just wouldn't go up very loud [BOSE]. This one, the Monster, I discovered let me control the volume through the remote, and it definitely was louder. I got confused as I was wondering why the buttons on the side of the speaker weren't working when I discovered my smart tv remote would control the volume which is WAY easier anyway. My BOSE had the same function - but it would only play super low which was annoying. That was a serious pet peeve of mine with my mom's speaker which I bought her a year ago. The new Monster speaker was the opposite and was loud. I actually had to lower the volume a little. The BOSE version which is more expensive wouldn't go up high enough! The best part is the sound quality. It's amazingly clear on voices and the special affects are just like WOW! My mom asked me to order her one for her main bedroom and I suspect will find herself using this one more. I think this is a better band. The only item I found a little off putting is that it's not that soft on the neck. My mom said it was fine, but my skin is sensitive. Silicone sometimes bothers me so I'll probably just put a cloth on top of my neck and lay this on top. That's the one area I think Monster needs to work on. My mom likes it better because she prefers the thin part behind her neck when she's laying in her bed watching tv [she has one of those adjustable ones]. Other than that, it's worth the money. FYI - This is not a tinny sound. It's literally like surround sound. You hear the noises going back and forth and wow...I was just so impressed. If you're looking for a wearable band that is affordable, this won't disappoint. I'm honestly surprised as heck that they are selling it for this price. If they flooded the market, these guys would win. I'm so glad I decided to try this one. I'm currently connected to a Samsung Smart tv.

## 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

### ⭐⭐⭐⭐ Best outdoor/active speakers for the price.
*by A***. on June 22, 2025*

Got these on Friday the 20th and so far, no issues at all. The sound quality is perfect for what I need at home, but the main reason I bought them is for work. I work in a warehouse where the noise level can hit 80–90 dB depending on the area, and these speakers have been a great solution. I’ve dealt with hearing issues in the past and also tend to get a lot of earwax buildup from using earbuds all day. I heard about these from coworkers, and honestly, they’ve been perfect for my situation. For the price I paid ($59.99 + tax), they really feel like portable speakers from brands like Bose, JBL, or Wonderboom — except they rest comfortably around my neck. I’d say they’re closest in feel and quality to JBL, especially with their water-resistant design. Bluetooth setup was super easy — just paired once, and now it connects automatically every time I turn them on. As for comfort, the weight is no issue at all. I’m used to wearing shoulder pads and carrying weight around my neck, so these feel pretty natural. Overall, I definitely recommend picking these up, especially when they go on sale. From what I’ve seen, they tend to go on sale every other month and the discount usually lasts through the month. (Edit/Added note after about 2 months) As many others stated I’ve come across an issue that really doesn’t bother but may be bothersome to others which is the bluetooth speakers will disconnect randomly (more commonly if you paused/no sound coming out for more than 5 minutes. They’re not totally an issue for me as they immediately reconnect sorta like it’s letting you know it’s on or you left it on for what I think. There are other times where the sound will crackle as if I’m a distance to where it can’t reach but is literally 2 feet from my phone. Overall I still recommend this regardless of the issues mentioned above.
