Beatbox, a dimly-lit karaoke bar in the West Village neighborhood of Manhattan, is outfitted with plush-velvet poofs and decorated with vintage vinyls and large photographs of concerts by artists like Lil Uzi Vert and Chappell Roan.

There are three private karaoke suites, one of which can fit 70 people. Performers stand on a stage with a wall made up of LED lights behind them, the lyrics of their selected song displayed on a 65-inch TV, belting into professional-grade microphones.

In October, Chelsea Lipscomb-LeSane, 31, a creative producer who lives in Fairfield County, Conn., attended an album release party at the venue, which opened to the public on Nov. 1. She knew right away that it was no dive bar karaoke experience.

“It feels like a mix between your coolest friend’s living room and a high-end recording studio,” she said.

Beatbox is one of many high-end karaoke spaces opening in New York and New Jersey restaurants, apartment buildings and even private homes. These spaces incorporate sophisticated sound systems and proprietary software — and often are fitted with lounge areas suited for a rock star.

The owners of Beatbox, Sara Goodison and Lannie Rosenfield Rydell, who met at Stanford University’s business school, spent six months renovating the space, which used to be a Black Tap burger restaurant (They said they found five milkshake machines during the build out.)

Singers can opt to freestyle songs or play one of two games built specifically for Beatbox that use artificial intelligence. One awards points for hitting the right notes — “It is like Guitar Hero,” said Ms. Goodison — while the other scores you based on how well you know the lyrics of the songs.

Performers can also use karaoke filters and auto-tune to make their singing higher or add vibrato. “It’s like an Instagram filter for your voice,” said Ms. Rosenfield Rydell.

Ms. Goodison wanted to get people off their phones and into social spaces. “We really looked at leveraging that technology, which is keeping people isolated and at home and alone,” she said. “If we are going to create a place that people are motivated to come to and spend time, it has to be this high tech experience.”

But Beatbox is not the only karaoke bar in town.

When Simon Kim opened Coqodaq, a fried chicken restaurant in New York City, he knew he wanted to have a karaoke room.

“I am Korean, and in Korea karaoke is a huge thing,” he said.

But understanding that social media had allowed everyone to make content from their couch, he knew he had to create a compelling space. So he tapped David Rockwell, the architect and designer behind the restaurant, to build the “sickest karaoke room,” said Mr. Kim.

Mr. Rockwell, who said this was his first time tackling a karaoke room, filled the 450-square-foot space with a large stage, embellished with 1,200 meters of Swarovski crystals. The side walls of the stage are made of a dark cork suited for sound proofing, and there are movable banquettes to fit different party sizes. The room was first plotted out as a 3-D model and took three months to build.

Mr. Kim said the cost was on the level of a luxury car.

Even residential buildings are getting in on the singing action.

At 1289 Lexington, an apartment building that opened two years ago on the Upper East Side, there is a $300,000 karaoke room that has heavy metal doors for sound proofing; 16 speakers; acoustically absorptive materials and a green screen for making music videos.

The idea was to create a space where teenagers could get off their phones, said Jill Bernard, the building’s director of sales.

“Play rooms are standard, and they are beautiful, but what happens when you are 10 and 12 and want an amenity that connects people and makes them smile,” she said. (Teens are still on their phones in the room. But at least they are making videos together.)

In RiverHouse 11, a high rise in Weehawken, N.J., residents have access to a karaoke facility that comes with four Fender Stratocaster guitars, a Yamaha piano keyboard and four Marshall amps.

Then there is the private home variety.

When they moved into a new house in Warwick, N.Y., in 2023, Darren McNeill, 38, who works in automotive sales and operations, and his wife, Rilke, 43, a physical therapist, turned their basement into a high-tech karaoke room and home theater.

“We wanted a place where we could go down and escape from things,” Mr. McNeill said.

They use an iPad to cast music videos onto a large-screen TV. It is connected to two speakers, optimally placed for the best acoustics. They sing along to the videos with a karaoke machine they bought on Amazon for a few hundred dollars; it came with a 12-inch woofer, two microphones and party lights.

But just like in the commercial spaces, their karaoke room is meant for community. Mr. McNeill said friends now invite themselves over to jam out.

“We are either legendary or notorious for it, depending on who you ask,” he said.
