Big Ocean, a three-member K-pop group composed entirely of artists with hearing disabilities, is redefining the limits of music and performance — one beat at a time.
Big Ocean seamlessly incorporates sign language into their performances, and their shows are built on extensive preparation using high-tech tools — vibrating smartwatches that pulse with musical beats and LED visual metronomes that flash timing cues during practice sessions.
This technological approach represents significant progress in South Korea’s entertainment industry, where career opportunities for people with disabilities have historically been limited.

The trio, PJ, Jiseok and Chanyeon, made their debut in April last year and recently wrapped a European tour marking their first anniversary. The band performed in four countries, including France and the UK, while promoting their second mini-album, Underwater, which dropped on April 20.
To achieve the precision crucial in K-pop’s demanding choreography and music, Big Ocean relies on technologies rarely seen in the genre. Members wear modified vibrating smartwatches that deliver rhythmic cues to their wrists and practice with visual metronomes — flashing light guides displayed on monitors — to help stay in sync.
Chanyeon uses a hybrid hearing device with Bluetooth that streams music directly from mobile devices. They also use a pitch-checking app and artificial intelligence voice conversion technology to support vocal training and enhance audio output after recordings.
“We each felt rhythm differently when dancing,” PJ said. “So when we’d play the same song and dance in front of the mirror, one of us would move faster while another would move slower. To solve this timing issue, we decided to memorize everything together and create our own cues with each other.”
This precision becomes critical during live performances, where unexpected disruptions can derail even experienced performers.
“When we performed in France, our fans were cheering so loudly we lost the beat,” said Jiseok. “But we looked at each other and quickly handled the situation — just like we practiced.”
Stage effects and certain musical styles create additional obstacles.
“When a lot of smoke comes up, sometimes we momentarily can’t see the stage movements in front of us,” PJ said. “Our concentration gets disrupted instantly in those moments.”
“When there’s no clear beat in a song, it’s really hard for us to stay synchronized,” Jiseok said. “When the bass is overwhelming, it’s difficult for us to catch it accurately.”
Despite these challenges, Big Ocean’s commitment to accessibility and inclusion has inspired their global fanbase — known as PADO — which has responded with similar commitment.
“While communicating with PADO, we’ve heard that they’re actually learning Korean sign language for us, or learning various sign languages to communicate with us,” Jiseok said. “When we see how much they’re preparing and putting in that effort, we feel so grateful.”
The group uses English for basic communication with international fans and incorporates Korean Sign Language, American Sign Language and International Sign to promote accessibility and inclusion.
FRUSTRATIONS: One in seven youths in China and Indonesia are unemployed, and many in the region are stuck in low-productivity jobs, the World Bank said Young people across Asia are struggling to find good jobs, with many stuck in low-productivity work that the World Bank said could strain social stability as frustrations fuel a global wave of youth-led protests. The bank highlighted a persistent gap between younger and more experienced workers across several Asian economies in a regional economic update released yesterday, noting that one in seven young people in China and Indonesia are unemployed. The share of people now vulnerable to falling into poverty is now larger than the middle class in most countries, it said. “The employment rate is generally high, but the young struggle to
ENERGY SHIFT: A report by Ember suggests it is possible for the world to wean off polluting sources of power, such as coal and gas, even as demand for electricity surges Worldwide solar and wind power generation has outpaced electricity demand this year, and for the first time on record, renewable energies combined generated more power than coal, a new analysis said. Global solar generation grew by a record 31 percent in the first half of the year, while wind generation grew 7.7 percent, according to the report by the energy think tank Ember, which was released after midnight yesterday. Solar and wind generation combined grew by more than 400 terawatt hours, which was more than the increase in overall global demand during the same period, it said. The findings suggest it is
IN THE AIR: With no compromise on the budget in sight, more air traffic controllers are calling in sick, which has led to an estimated 13,000 flight delays, the FAA said Concerns over flight delays and missed paychecks due to the US government shutdown escalated on Wednesday, as senators rejected yet another bid to end the standoff. Democrats voted for a sixth time to block a Republican stopgap funding measure to reopen government departments, keeping much of the federal workforce home or working without pay. With the shutdown in its eighth day, lines at airports were expected to grow amid increased absenteeism among security and safety staff at some of the country’s busiest hubs. Air traffic controllers — seen as “essential” public servants — are kept at work during government shutdowns, but higher numbers
Elvis Nghobo tried to get into four different professional schools in Cameroon, but could not make it. Frustrated, the 34-year-old turned to selling food at a market in Yaounde, the country’s seat of power. Nghobo blames his woes on what he calls a corrupt education system that favors children of the elite. As the central African country prepares for Sunday’s presidential election, he said he would not be heading out to vote. He called the results a foregone conclusion for 92-year-old Paul Biya, the world’s oldest president, who has ruled for Nghobo’s entire life. “He is already too old to govern, and it’s boring
