It's like being front of the artist, next to them in the studio or on stage. I personally tune every Monster headphone and speaker to bring you closer to the music ''you have to hear it to believe it”. Portable Bluetooth Speaker with Handle Design Measured 10.59*9.13*1.64in, and weighing 2.2 pounds, Monster Sparkle Mini is not only a portable Bluetooth speaker but also a lightweight karaoke machine that you can carry around for indoor/outdoor use.

Review: Portable Bluetooth speaker - I absolutely love this speaker! It's so awesome with its portable size and two handles The sound is crystal clear, although you might need to turn up the volume for anything connected via Bluetooth. I really appreciate the option to insert a microSD card filled with music. Plus, unlike most other speakers, this one even has FM radio. The only downside for me is that there isn't much bass - I'm a bass-head, so I need my bass. Nevertheless, it still sounds fantastic, and I enjoy listening to podcasts on it. It's quite large and perfect for backyard use, although it may not be as big or loud as speakers specifically designed for outdoor use. Overall, it's a fantastic value! Review: Amazing!!!! - The good: This is actually one of the best rechargeable Bluetooth speakers Ive ever heard. Even though it has a small speaker, it has phenomenal sound quality and is loud!! But still clear as a bell. I can't say enough great things about the sound quality. The battery life is amazing so far. Ive charged it once and have played it for several hours a day for 3 days so far. The battery meter hasn't moved. "The mic input" I plugged in a multi mic interface using my guitar and a mic. I played and sang through it to get an idea of what sound quality id get out of it. Wow! This speaker will rival any battery powered speaker of its class. And possibly rival any 120v standard plug in guitar amp of comparable size. Im very impressed with the MFS 1. "The not so good" My only complaint is, when using a thumb drive (usb) you cant directly go to an individual file or chapter. It plays from track 1 of the first chapter, and then plays every song after. Now, if you've specifically set up a thumb drive with that in mind. No problem! But if you've got thousands of songs from every genre, it could be a party foul to go from Busta Rhymes to Barry Manilo! πŸ˜‚πŸ€£ But on a serious note. If compact size with outstanding performance is what you're looking for. You will not be disappointed. (Note to Monster) Please put reverb on these speakers in the future. That would set this speaker way ahead of most on the market. ## Features - 【 Multiple Connectivity Options 】 -- Loud Bluetooth speaker offers multiple audio source output options and supports such as AUX input, TF card slot, and FM radio.
