Great if it meets your specific needs.
I was gifted the Panasonic Sound Slayer Gaming Speaker in exchange for an honest review on Panasonic’s website.
My primary reason for wanting to try these speakers is due to being quite a frequent raider in Final Fantasy XIV while also having quite bad tinnitus, which results in me avoiding headphones wherever possible. In my very specific use case it does the job quite well. That said, for most people, it can be a little hard to recommend. Not to say it's a bad product, which is not the case at all. I'm still very happy with them. They're just a very... niche product.
The sound quality is quite nice, but could be better. The mic quality is good, but could be better. The fact that it's wired is not ideal, but not a deal breaker. As someone who is going from speakers with a separate mic to using just the SoundSlayer, I can say I have enjoyed my time using it and can see the pros. However, it would be fairly difficult to recommend to most when the job can be done just as well with a good quality mic and headphones, which will provide better sound quality and better mic quality without having what you're listening to be audible for everyone around you as well.
That said, if you are someone who is like me who wants to tailor their individual sound setup to meet very specific needs, and these speakers meet those specific needs, then you will likely enjoy this product very much. For fans of Final Fantasy, the fun little additions are quite cute, and having a personal surround sound experience is quite interesting, and I do enjoy it quite a bit.
All in all, I can definitely recommend it to those who are specifically after the unique features that these speakers provide, but would not recommend it to anyone who can make do without, especially for the price.
