We’re delighted to announce that the Zello Original White Noise Machine has been chosen to take pride of place at the MGM Resorts International’s 5-star Cosmopolitan Hotel on the iconic Las Vegas Strip.

Renowned for its vibrant nightlife, world-class entertainment, and round-the-clock energy, the Las Vegas Strip is a destination that never sleeps, but its guests still need to. That’s where Zello comes in.

Designed to create a calm and consistent sound environment, the Zello Original helps to mask the city’s constant buzz, allowing guests to unwind and drift into deep, restorative sleep. By gently smoothing over disruptive sounds like street activity, nearby music, or hallway noise, the device ensures that every stay at The Cosmopolitan is as relaxing as it is luxurious.

The introduction of Zello at The Cosmopolitan reflects a growing trend among leading hotels to invest in sleep-focused guest experiences. Quality rest is now recognised as one of the key contributors to guest satisfaction, influencing reviews, return bookings, and overall wellbeing.

“At Zello, our mission has always been to help people sleep better, wherever they are,” said Dionne, Head of Partnerships at Zello. “Partnering with such an iconic property as The Cosmopolitan is a fantastic milestone for us. It shows how seriously the hospitality industry is taking sleep quality and guest comfort.”

By offering Zello Original devices in 50 guest rooms, The Cosmopolitan is setting a new standard for luxury sleep amenities, combining cutting-edge design with the timeless appeal of a peaceful night’s rest.

For guests, it’s the perfect balance: the excitement of Las Vegas just outside, and the soothing sound of Zello within.
