o alto-falantes são bom, mas podem melhorar, tive problema de conectividade, mas tambem meu computador é mais antigo, é possivel que seja por isso.

I did some research a while ago and I really got interested in the Sonos Roam 2, so I'll list what led me to that thought

Sound Quality: The reviews I saw on youtube/li led me to believe that it had good audio quality.

Portability and Design: What stands out here is the fact that it's attractive and IP67 certified, so I can use it in the pool and on the beach hahaha.

Connectivity: The fact that it has Bluetooth and Wi-Fi brings a flexibility that I've been looking for and find very interesting

Integration with Voice Assistants: If you have an Alexa at home, it can interact directly with it, making your house a home of the future.

Battery: I didn't think it was that good, but it was of OK quality, as mine has lasted about 4.5 hours.

JBL Boombox 3

It is impossible to talk about good audio devices without mentioning the JBL speakers. The Boombox 3 is probably one of the best devices from JBL and for a good reason, the sound volume that it can reach is fantastic and won't get the sound distorted, and if you buy a speaker the last thing anyone wan't is the sound get distorted.

One of the good fictions of this devices and many others from JBL, is that he can pair with other devices from JBL since it's a wireless device, so it is the perfect choice for small parties with your friends groups, everybody will enjoy the great songs with the best quality you can have.

I think in terms of speakers the Sony brands still stands out, I agree with most of the people that the brands isn't so good as it already was one day but it keep making really good sounds devices that keeps really sound fidelity.

The SRS-XB100 could not be the best one but is one of the best if not the best of the smallest ones and he do a good job with less than 50 USD. And people like me isn't so much fan of earphones or headphone, so I think its the best cost-benefit in the market and do a great job.

How it has planed as a portable device it has great connectivity with all the mobile devices, like smartphones, tablets and laptops, and the most important thing it has a good battery for its size so you don't need to worry with it getting uncharged all the time.

On hi-fi level, and if you have decent amps: all the bookshelf speakers by B&W. 100-2000$ range, with the lower price being found on ebay or facebook marketplace used. If you want to spend more KEF is a good next tier. Going higher than KEF, I would recommend having an audio engineer build some for your rooms measurements.
