I fly every weekend for work. The case and speakers stay in my check in bag for travel. Still able to get a ton of clothes, and accessories without going overweight. They even made the trip with me to Dubai! For portable studio monitors you can’t beat it. Also you can be Bluetooth connected to your phone while also having your studio mix running through the monitor mix, So if you stop to take a break you can still send some music through. I like em! I will say I got em for 50% off for Black Friday so maybe wait till you can find a deal.

I own presonus 3.5 woofer and 50watts cost $99 at Amazon. I just bought krk aux4 power 100 watts. Cost $199 at Amazon. Compared to KRK, Presonus is more powerful and sound better. I just gave KRK back, and I don't like it. all BS

The media could not be loaded.

EDIT: KRK_stayawake on github has a 10hz_tone.wav that you can loop in windows media player or another player and it will keep the speakers awake without any perceptible sound. Kind of annoying having an extra window open, but i can run this while I'm working and close it when I'm finished to get around the forced sleep "feature" for power savings. The intended way to play it in browser is no longer easy, as browsers have disabled autoplay.Speakers sound great, however the main thing I've had to consider returning them for (or try to get used to) is that they turn off automatically after 30 minutes without sound. With NO way to turn off this feature. You have to wake them up every time you sit down by pressing the power button twice, and worst of all through USB it takes a good 10 seconds to start hearing sound. Now while this might be great for power savings. I should be able to choose if i want to waste my electricity bill in the name of convenience. All drivers like these DO take up a decent amount of power even while off. I can hold it while they are on to manually put them to sleep as well if i want (I don't). I am trying to get used to it in order to be environmentally friendly and save on electricity. I really wanted the smaller GoAux 3s to save on desk space which is at a premium for me, however went with the larger GoAux 4s (for $50 more) to get the 3 extra premium features. (USB input, TRS Left/Right Input, and Auto ARC) (ARC = Automatic Room Correction, that calibrates the speakers to sound better in your room by listening to feedback from itself through a mic that they include in the box.) I was not able to get AutoARC to work by reading the manual. Really, all I wanted was the USB input because I tend to get distortions and interference from AUX cables, AUX cables also tend to be flimsy and fall apart quickly. They did not include the USB Type B cable in the box. I had to go out and buy one separately. After plugging them in, I was surprised to see that they do not care what the windows pc master volume is set at, even when muted or at 0. They only go by their own physical on-speaker knob for master volume, and you can dial in using things like software specific digital volume control (eg volume slider in Youtube videos, slider in Spotify) that will also contribute to the sound up/down. I assumed since they were USB, they had some kind of included software control center or driver, but they don't. The stands also add to the overall size. I wanted to leave them off to save space on my desk, however I need them on to provide enough leverage to press the button twice to wake them up from sleep every time I sit down otherwise they slide back from the force. A benefit of using the stands is it allows them to be angled upwards incrementally. I would love to see GoAux include a software component for these class of speakers that allow us to dial in sound settings, as well as turn off auto-sleep, or at least allow and increase wake sensitivity to sound. Waking up from any sound at all instantaneously through sound would be optimal for me and should be achievable from some kind of developed driver I would assume. I have not been able to wake them up using any sound yet over USB, however other people say they can when the sound is loud enough. There is a hack online that someone made that will play a claimed inaudible sound every 30 mins that keep any of your KRK speakers awake, since this is a known forced feature of KRK. I have not tried that yet. I have not tried TRS Left/Right input or Bluetooth yet, and after trying to use AutoARC I have not been able to get it to work. Holding the button to activate it as stated in the manual does nothing. Just so you know, you would use TRS Leftright if you want to use aux on the other end. There is no aux port.So in conclusion, the speakers are built extremely well and look cool with the yellow highlight, they sound great to me as an average user. Every detail of sound is audible to my untrained ears. That is all I really needed them for, monitoring production audio. The price is reasonable and the build quality and look makes the price worth every dollar. The auto sleep function after 30 mins without sound to save on power is irritating, with no way to turn it off, and through USB it takes 10 seconds to start playing sound from sleep. I wish they included a software to dial in sound settings and turn off or manage auto-sleep. Also the mic input on the front of the speaker is only for the AutoARC calibration mic, not for regular microphone to passthrough into the OS, unfortunately. The carrying bag is also quality.

Speakers enter sleep mode after 30 minutes of no sound - The only way to wake up speakers is to toggle power switch on and off. This is a complete deal killer. I'm returning speakers to Amazon.

Me encantaron son muy portatiles, viene con su funda de viaje y la calidad de materiales/sonido es excelente!

Los KRK Goaux 4 son realmente increíbles, se nota la calidad de audio de estos monitores. No ocupan tanto espacio y son fáciles de movilizar, además de contar con conexión bluetooth para conectarlos a cualquier tipo de dispositivo. Actualmente los utilizo para mi home studio y son conectados mediante un cable RCA a dual TS a mi controladora. Posteriormente los conectaré a una interfaz de audio dedicada mediante cables TRS a TRS lo cual mejorará aún más la calidad de sonido. Excelente compra!

pleasant voice!Standby and Off Mode?? That's great! Multi-function knob. Turn clockwise to raise volume and counterclockwise to reduce volume. Push twice to wake up system out of standby mode. Push and hold for 3 seconds to put system into standby mode. (The LED ring will glow amber when the system is active and turn off when the system is in standby mode.)

If there is soft or no sound after about 30 minutes, these speakers will automatically go into Standby Mode.To turn it back on, you have to reach behind and flip the power switch twice. I didn't know this about these speakers and after some research, it's a plaque amongst KRK users. Many are having to hardwire modify their power sources to disable.They sound awesome but it doesn't matter as this stupid feature is a major annoyance and can easily break your focus or attention.

Sehr hochwertig und anscheinend gebaut wie Panzer.Würde sie wieder kaufen und kann sie empfehlen.Die beigelegte Transporttasche ist ebenfalls von guter Qualität.
