Bae Ki-seong, also spelled Bae Gi-seong, is a South Korean singer best known as a member of the duo CAN. In 2026 he spoke openly on television and in the press about a sudden hearing problem in his right ear that began with tinnitus. His account is a valuable reminder that ringing in one ear, together with a drop in hearing, is a reason to see a doctor quickly.
What Bae Ki-seong has said about tinnitus
Appearing on the TV Chosun program Lovers of Joseon in 2026, he said he had developed sudden hearing loss in his right ear and that it started with tinnitus on that same side. According to the Korean sports daily Sports Kyunghyang, he described the ringing as the first sign that something was wrong.
In July 2026 he gave an update, saying that he hears the tinnitus 24 hours a day and that he was receiving medical treatment. His privacy deserves respect, and it is best not to guess beyond what he has shared. What his story makes clear is how disruptive constant ringing can be, and how important it is to take sudden changes in hearing seriously.
Why sudden hearing loss is an emergency for anyone
Sudden sensorineural hearing loss is a rapid drop in hearing, usually in one ear, that develops over a few hours to a few days. Often no clear cause is found. It can strike singers, office workers and athletes alike, and it is not limited to people exposed to loud music. Ear, nose and throat specialists regard it as urgent because early evaluation gives the best chance to act while options are widest. Signs that often come with it include:
- New ringing in one ear. Tinnitus on one side can be the first thing people notice, sometimes before they realize their hearing has dropped.
- A blocked or full feeling. Many people think the ear is simply plugged with wax or water, which can delay care.
- Waking up with the change. The loss is often noticed first thing in the morning or over the course of a single day.
- Dizziness or spinning. The inner ear also controls balance, so vertigo can come along with the hearing change.
- Trouble on the phone. Struggling to hear calls on one side is a simple clue that one ear is not working as it should.
Everyday habits to protect your hearing
Not every case of sudden hearing loss can be prevented, but daily habits help protect the ears you have and make it easier to notice changes early. NIOSH recommends staying at or below 85 decibels over an eight-hour day, and each 3-decibel step above that halves the safe time. For performers, that means watching stage volume and in-ear levels; for everyone, it means taking care with headphones, concerts and loud tools:
| Habit | How | Why it helps |
|---|---|---|
| Check both ears | Now and then, listen to a call with each ear in turn | A simple way to notice if one side has changed |
| Keep in-ear levels moderate | Set stage monitors and headphones only as loud as needed | Lower daily exposure puts less strain on the inner ear |
| Protect your sleep | Use soft background sound if the ringing is louder at night | Rest makes constant ringing easier to live with |
| Daily ear support | A formula you have reviewed with your doctor | Everyday support for ears and mind |
If you have already had sudden hearing loss, keep every follow-up appointment and ask your audiologist whether a hearing aid or sound therapy could help with the ringing that remains.
What tinnitus is, in plain terms
Tinnitus is the sense of hearing ringing, buzzing, hissing or humming when there is no outside sound. Most cases are subjective, meaning only the person can hear it, and they are often tied to changes in hearing. Less often, tinnitus is objective and comes from blood flow or muscle movement near the ear, which a doctor may be able to hear. Common triggers include noise exposure, hearing loss, earwax, ear infections and certain medicines.
When tinnitus follows sudden hearing loss, it can be very loud at first. Over time, many people find it less intrusive as the brain adjusts, a process called habituation. Sound therapy, cognitive behavioral therapy and hearing aids are well-established ways to make the ringing easier to manage, and an audiologist can help build a plan around your needs.

Common questions
Does Bae Ki-seong have tinnitus?
He has said that his sudden hearing loss in the right ear began with tinnitus on that side, and in July 2026 he said he hears the tinnitus around the clock and was receiving treatment.
Can tinnitus be a warning sign of sudden hearing loss?
Yes, it can be. New ringing in one ear, especially with muffled hearing or a full feeling, should be checked by a doctor right away rather than left to see if it passes.
Does hearing always come back after sudden hearing loss?
Not always. Some people recover part or all of their hearing, while others do not. That is why fast evaluation matters, and why follow-up care and hearing support are important afterward.
