Hi, What are the options for the lights on the speaker , can you set it to one colour and not to pulse

Asked by: Ajchery
Hi, and thank you for your interest! You have three randomized patterns and one that follows the music. You cannot get other effects, and one colour only is not available.

Is this waterproof like the boombox? 

Asked by: Braimai123
Hi and thank you for your interest! No, this model is not waterproof, and has no IP rating. What you can do, if you want to use it where there is risk of rain, is to wrap a plastic garbage sack around it. Normal plastic will not influence the sound very much, and will protect well against the moisture.

How come it has a 10000 mah battery and the boombox has 20000 mah battery and is cheaper?????

Asked by: Ollie martin
Hi Ollie, The Boombox is cheaper than the JBL Partybox because of the features and components used in the Party Box 300. The storage capacity of a battery also has no influence on the price of a product.

What is watts on the 200 plus 300 

Asked by: Zedniya
Hi. You can find this spec in the owner's manual. We state: Total output power 120 W RMS. This is true for both the 200 and the 300, but of course the 300 can run on its internal battery as well.

What db is the jbl partybox 300

Asked by: Tiarnan123
Hi, How loud a speaker plays in pure dB is not very relevant, nor does this get tested. This requires a lab environment and results from these types of tests can never be reproduced in a "home" environment. The power output is 120W RMS and should be loud enough to fill a large room. If you order the Partybox 300 directly from our website, you can test it out for yourself. We have 30 days return right on all products sold directly by us, and if you're not satisfied, you can return the Partybox 300 to us for a full refund.

Hello, i have question about if it possible to connect via bluetooth to ps4 pro? Thanks.

Asked by: Gregii04
Hi and thank you for your interest! No, Sony has chosen a Bluetooth connection that does not support stereo audio streaming over Bluetooth, also known as A2DP. This means that only Sony headphones, and a few others, can communicate with a PS3 or PS4. This is of course also true for Partybox it cannot connect to PS4. However, one of the differences between PS3 and PS4 is that PS4 controllers have an analog headphone output, so you can access the signal in analog format. You can use this output for a cabled connection to the AUX input of Partybox. It is not too elegant, but it can be done. I hope this helps.
