I have over 300 reviews from Korean and international students, but here are just a few.

I immediately decided to enroll on the course with Jason after the free trial lesson.
Has great knowledge of vocal techniques, tailors the exercises specifically for you, provides reference material and on top of that communicates great in English. Really laid back person as well so the classroom atmosphere is not stressful at all. You won’t be disappointed!

I went to Jason’s studio in Seoul yesterday and it was such a great experience! Very kind and creates a relaxed atmosphere where you can feel comfortable.
Even when you feel unsure about your singing,
there was no pressure at all.
Within just 30 minutes of the trial lesson, I already learned how to handle my voice better and noticed real improvement.
The studio is also very foreigner-friendly, and English is no problem, which made me feel even more comfortable. I’ll definitely keep going there, and I can highly recommend this studio to anyone interested in singing!

Great teacher! After just one lesson, I could already hear a noticeable improvement in my voice. He offers clear, detailed techniques that are easy to understand and apply. Very professional and encouraging throughout the session. He speaks English also which made communication smooth. Highly recommend to anyone looking to improve their singing or speaking voice!
-Ellie, USA-

Very passionate teacher! You can really feel that he loves to teach and that he does everything to make learning fun and unique. I’m receiving his lessons in English and it has really been no problem at all, he is really flexible with explaining how to train your voice. His studio is also very easy to find, you just go to hapjeong station, and then its like 3 minute walk only. The toilet is also always very clean and there is water to drink if you are thirsty. If you are still hesitating if singing is for you, book a trial with him and you will find out that singing is for everyone, you will discover a new passion together with him.
-Danny, Netherlands-

I’m a Korean language teacher, and I recently visited this studio after a Dutch friend recommended it to me.
I had been struggling with voice projection and hoped to get some help.
The space was cozy and welcoming, but what really impressed me was how quickly the teacher understood my problem and offered clear, practical guidance that I could immediately apply. Within less than 20 minutes, I could already feel a difference in my voice. It was clear to me that this teacher is both passionate and highly skilled.
Although I initially came for help with vocal technique, the class was so inspiring that it made me want to start singing too!
It was a free trial lesson, but I left feeling like I gained so much more.
If you want to sing Korean songs better-especially if you’re into K-pop, I highly recommend trying a free class here. I’m definitely going to recommend it to my students who love
-Jay, Korea-

I went for the 30 minute trial session, and as someone with no singing experience I was a bit nervous. The session went really well and it was tailored to my vocal issues. I definitely felt more confident and knowledgeable by the end, and I highly recommend booking a session with them!
-Lea, France-

Went in for a trial and immediately signed up for a pack of 8 lessons afterwards. The instructor was very passionate and understanding.
I could feel the difference immediately after trying the techniques he showed me. looking forward to taking lessons twice a week from now on!
-Anh, VietNam-

I had a great experience at VLA Vocal Labs! I really appreciated that my vocal coach, Jason, is fluent in English. That immediately took away one level of nervousness and made me feel much more comfortable. Jason was very welcoming, gave me useful insights right away, and started working on my training from the very first lesson.The studio itself is clean and has a very warm and inviting atmosphere
-Erika, Canada-

I had a wonderful experience at VLA! I did a trial lesson with Jason and was amazed by how much information and advice he managed to pack into just 30 minutes. It was my first ever singing lesson, and he immediately identified the main issue with my voice, structuring the exercises to address it and help me go beyond. By the end of the class, I was able to belt out a note in a way I never knew I could; it honestly felt like, for the first time ever, my real voice was coming out. Jason kept the lesson compact and productive but also really fun and comfortable. I was nervous, but he kept encouraging me the whole time, which I really appreciated 🙂 He even recorded the entire lesson and shared it with me right away, which is so helpful! I’m still amazed by how much I learned in such a short time, and I’d highly recommend VLA to anyone interested in trying out singing lessons!
-Veronika, Finland-

After trying many singing teacher, I finally found someone very professional and who has good sense.
Good point is, the teacher is listening to your request, and solve the problem very efficiently.
If you are looking for a great singing lesson in English or Korean, don’t hesitate, that’s the place to be!
-Gauthier, France-

I had a vocal coaching session with Jason, and it was genuinely one of the best experiences I’ve had in a long time.
Although it was just a trial, he was professional, encouraging, and really knows how to bring out your unique sound.
What I appreciated most was how he balanced technique with confidence-building.
Using simple ways to break it down for a novice like me.
I walked away not only singing better, but feeling better about my voice. Highly recommend him to anyone who wants to grow vocally and enjoy the process.
