Known for their premium-build quality at reasonable prices, Brainwavz's new B-Series line of earphones come with "Balanced Armature" technology for a richer listening experience.Priced at Rs 7,499, B150 falls under over-the-ear design of headphones and comes in a small form factor.Here is what works for the device.The compact design allows for a comfortable fit. Small angled nozzles are ergonomically designed, ensuring maximum comfort over longer listening periods.After the Y-split, there is a cinch that slides up and down to keep the earphones in place more securely, especially with over-the-ear wear.At the core of the earphones is the "Single Balanced Armature" driver that provides better treble performance than dynamic drivers, has faster response and more detailed sound.To review the audio performance of B150, we played various genres of tracks. Overall, we did not find any weakness.On tracks with intense sub-bass content like "Can't Hold Us" by Macklemore & Ryan Lewis, B150 delivered thumping bass beats, vigorously complementing the pace of the lyrics and will surely captivate you.The earphone also remained distortion-free, even at unsafe volume levels. On classical and non-bass heavy tracks, B150 sounded rich and balanced. To drive maximum comfort and well-balanced sound, correct selection of eartips is necessary and to ensure this, B150 comes with several sets of eartips of different sizes and designs to let you find the best fit.Conclusion: If your music library includes hip hop, electronica and bass-heavy tracks, B150 is for you.
