Hello Fred,<br /><br />Thank you for taking the time to review the Monster Z6. We&#39;re glad you&#39;re enjoying the sound quality, bass and lights.<br /><br />We appreciate your feedback regarding the lack of battery. The Z6 is designed as a plug-in PA system. To maintain its high-power output, it requires a constant power source.<br /><br />If portability is a must for your setups, please reach out to Sam&#39;s Club to verify the return policy and check if you are within the return Window. You can email us at support&#64;mymonsteraudio.com, where we can recommend one of our battery powered Monster speakers.<br /><br />Best regards,

Hello,<br /><br />Thank you for your feedback. We love that you are enjoying your X6, but we&#39;re sorry to hear you&#39;ve run into trouble trying to pair it with the Z6.<br /><br />The X6 and Z6 are compatible and can be linked together using the TWS feature. If you&#39;re having trouble trying to get them synced up, please reach out to our team directly at support&#64;mymonsteraudio.com. Our agents can walk you through the correct pairing steps.<br /><br />We also appreciate your feedback regarding a rechargeable battery. Because these are high-output speakers designed for maximum performance, they require a constant power source. Adding a battery to this type of system would result in a very short battery life, but we always share this kind of feedback with our development team for future designs.<br /><br />Best regards,
