The IP67 rating, shock resistance, great battery life, and compact size of Session 540 Party Speakers mean you never need to worry about whether they can handle your lifestyle. Snow, rain, beaches, lakes, these speakers can handle it all.

Pretty much. As long as you're not taking them into the deep end of the pool, these speakers can handle water no problem.

Their IP67 rating means Session 540 Party Speakers are dustproof. So go ahead and take them camping, climbing, mountain biking, or wherever.

You can use the directional pad to cycle through preset EQ modes (Signature, Outdoor, Indoor). Press the Right or Left button on the directional pad 3 times (3x) to cycle through the different modes.

With party mode you can link your Session 540 speaker with up to 99 other Session series speakers.

With your Session 540 powered on, you can start party mode by pressing and holding the party mode button for 1 second. Release after you hear an audio tone. You have started a party, and this is now your “HOST” speaker. The HOST speaker will start a broadcast that other Session speakers can find. Like a radio station, the HOST will only broadcast music. All other functions, like Volume and Bass boost will be controlled separately on each individual speaker.

To add a “GUEST” speaker to the party, don’t worry about disconnecting any devices. Simply press and hold the Party mode button for 3 seconds. Release once you have heard two audio tones.

You are now linked in party mode. Repeat "GUEST" steps for as many other Session speakers as needed.

With True Wireless Stereo, your Session speakers can create true left and right stereo sound to play full, and more immersive music.

With your Session speakers on, and connected to each other using party mode, triple tap the party mode button. You will have to perform this function for both the HOST and GUEST speakers individually.

Your speakers are now in true wireless stereo mode.

Once both speakers are in true wireless stereo mode, the HOST will act as the LEFT speaker, and the GUEST will act as the RIGHT speaker.

Fully charged, Session 540 Portable Speakers have about 17 hours of battery life.

Session 540 Portable Speakers' rapid charge function can give you up to 2 hours of battery in just 10 minutes of charging.
