For those who are looking to use this as a studio monitor, go ahead. We all can't afford $300+ speakers, so just get this and do what you gotta do like me and everyone else. However, keep in mind that it doesn't play below 70hz, so that low kick and strong subass will be lost, and it is noticeable. But it ain't bad. This is made for media consumption, and rightfully so, but you gotta start from somewhere. This opens a path for you to make your first step, and that is important to making progress.Now to the review:These are great and packs a punch, can get loud when it wants to. You can adjust the highs and lows with the knobs on the back of the left speaker to adjust to your room setting. I tuned mine to be flat to closely match my Audio Technica ATH-M40X headphones for monitoring, I know, these aren't made for that, but idc. It gives me a nice reference on levels and stereo sound, which are easier to catch than on headphones.It's a good buy for listening to music, but it ain't gonna impress the bass heavy crowd.

Funcionan perfectamente y la batería es inigualable

These are fantastic for powered + passive! The heat from the powered speaker is there, but very minimal. It's as loud as you would need for small areas/where 3.5" monitors would be appropriate. Would I use them to produce? For amateur work, absolutely. For professional work, I'd step up to dual-powered, as a minimum requirement.The best features are the convenient size, light weight, and the acoustic tuning. For only $100, having acoustic tuning is a pretty big deal. It could do with a bit better output to headphones (I use 600Ω headphones and I have to really crank them up), but it's manageable. The plastic feels a bit cheap, but they're very sturdy.Main issue is the lack of integrated RF protection. I have a GSM phone, which when placed to close to the powered speaker, presents very audible feedback. Again, easy enough to workaround; just move the phone away from the speakers. 10-12" away seems to be fine.For the price, the sound is great, no question. But it's still lacking range, making uncompressed audio files not so much different from a high-quality compressed file, so I can't give it a 5-star.I definitely recommend them for amateur music makers, or those who want good, neutral media speakers for their desktop.

They work great. I use them mainly for music productions and my beats sounds pretty nice. You can hear them in my Spotify: Duja MusicMy only complain is the Bass. The bass its ok but for $100 I’ll deal with it. :)
