Sennheiser launched the Momentum True Wireless 2 earphones earlier this year, which, while excellent when it comes to sound quality and features, are definitely on the expensive side at Rs. 24,990. A big reason for the high price is active noise cancellation; while this feature does contribute to the superb overall experience, it also puts the earphones out of reach for many buyers. Sennheiser's latest pair of true wireless earphones, the CX 400BT, is positioned to address that very problem.
