Isolate audio while traveling? As long as you check the box next to the 15 % off coupon, this Amazon Prime Day deal will knock the four-speaker pack to$ 400. That’s the best price I’ve seen all time, and it might go away when Prime Day is over on July 11.

Even though I review these items for CNET, a quick search for Mobile speakers online results in dozens upon dozens of choices that quickly turn out to be quite overwhelming. There are more well-known Bluetooth speaker choices as well as healthy purchases, such as the Soundcore Boom 2 by Anker and the JBL Charge 6 by JBL, both of which I have personally used. However, each Bluetooth speech has a distinct function, so I should consider what I want to get out of it when purchasing a new one.

A dynamic speaker is what I’m looking for. one that is lightweight but high-quality sounds. One that I can use either at home, at work, or shove up at a garden party. Where do Rocksteady’s Stadium 2.0 speakers&nbsp come in? For any summertime activity I have going on, I can link an infinite number of high-quality speakers to the Stadium, including a mobile sub-woofer. They have up to 30 days of battery life and are cordless, convenient.

A Bluetooth speaker that can change from a simple vacation friend to a full-fledged group set-up.

Most other Bluetooth speakers can’t do it, so Rocksteady’s Stadium 2.0 kits aim to range from a single side speech to a neighborhood surround sound system without using any cables, and also deliver high-quality sound.

You can choose a single speaker ($ 150 ), which comes with a dual-driver setup ( a powered tweeter and mid-bass driver ), as well as dual bass drums, to deliver crisp highs, warm mids, and some of that low-end thump. In my home or business, which is a relatively small space and where I don’t need too much, I use a single loudspeaker.

A dedicated subwoofer ($ 180 ) can be added to your speaker to improve your listening experience. You notice the difference if you listen to hip-hop or EDM, or if you watch a film with a lot of gunfire and bombs, and you notice the difference. The speaker and subwoofer pack ($ 400 ), which includes two speakers and a sub, is definitely recommended if you want to go this route.

However, the Rocksteady Stadium 2.0 thrives in the four-speaker and bass group. Yes, it costs$ 600, but if you have the money, you can join as few or as many speakers as you need for any occasion. I use this layout the most for everyone, from yard barbecues and events at Airbnbs to listening events and movie night.

It’s as simple as a touch of a button to set up all of your listeners.

Getting Stadium 2.0 up and running is fairly straightforward. Any speech that has a unique” Rocksteady_XXX” ID can be turned on and then connected to your phone by clicking the Bluetooth logo.

The first speaker may serve as the number. After that, just click the Stadium switch on the host and therefore put each additional satellite speaker, or mobile sub, to the mesh. The best part of it is that when your speakers are connected, they will all immediately connect when you turn them on again, without you having to re-pair them. It takes about 15 hours to combine them all.

With a swift switch, you can create a two-channel pc rig for your computer or a number of dual-duty speakers for surround sound in your backyard. Each speaker can then be assigned a left, right, or sound duty designation.

Each package charges over USB-C, but grabbing any phone brick will keep them all in sync for the specified 30-hour run time. Each channel is in sync up to about 150 feet. Additionally, the four-speaker system has a carrying case, making it simple to transport your speakers.

In essence, there is no application, no cables, and no pain; all you need is to spot, pair, and press play.
