User Reviews
Pretty good
Stock tuning is very bad. But due to separate DACs it responds to EQ. Tweak the EQ, bring down bass and increase treble. Voila! You will get one of the best sound experiences in this price segment. Battery life and call quality is good.

I bought these earbuds on **July 11, 2025, at 9:30 AM**. This is the first review of these earbuds after their launch in Flipkart. My main preference is music. The sound is well-balanced. Singer's vocals, bass, treble, and music separation are all clean and amazing. I am fully satisfied 😌. Noise cancellation, transparency, and call quality are also good. However, one disadvantage is that they are overpriced. In conclusion, if your main preferences are music, watching movies, and good call quality, then definitely go for it. 🔥
