I bought a second one because I liked the sound quality; it’s much more enjoyable now that I’ve connected it via stereo. Thank you..

This is for the normal, non-core, model. I've had a hard time trying to find out the differences between the normal and core models. Internet says the drivers are different sizes, but I can not confirm. Build quality is good. All the plastics feel solid and the soft rubberized texture feels pleasant to the touch. The elastic strap is shorter than I expected. Not long enough to carry it like a cross body bag. Good enough to use as a carrying strap or to hold a phone against the back. The sound quality is better that expected. The bass reflex "ports" on top provide a noticeable and punchy bass. Not a fan of the app. I would prefer the lighting settings to be a physical button like on previous versions. Not a fan of the ai/radio button. I wish I could reprogram this to Google assistant or a Spotify playlist. I

It is a speaker that meets all expectations.

The clarity of the sound is amazing, however the bass is severely lacking in my opinion. It vibrates like the bass wants to be there but when music plays its all mids and highs. But again very clear and crisp. I guess perfect for outdoors where bass loses its boomieness and rumble. But overall a good speaker as far as smaller Bluetooth speakers goes.

I like this speaker. I use it in my vehicle. Its a good size and sounds really good. It could be a little louder. Keeps a charge forever it seems like.
