Sennheiser CX True Wireless Earbuds Black

Sennheiser CX True Wireless Earbuds

The Sennheiser CX True Wireless are in-ear headphones that deliver the brand's signature sound through 7mm dynamic drivers. They provide up to 9 hours of playback on a single charge and a total of 27 hours when combined with the charging case. Intuitive touch controls manage music, calls and voice assistants, while an IPX4 rating protects against splashes. Four ear adapter sizes ensure a secure, ergonomic fit for passive noise cancellation.

Commuters and listeners wanting long battery life

Buyers who require active noise-cancelling circuitry to suppress low-frequency drone will not find that technology here. The passive isolation depends entirely on the physical seal created by the ear tips. Users who prefer over-ear or on-ear form factors should consider a different style of headphone.

27-hour total battery life with charging case

The case stores an additional 18 hours of energy, extending the earbuds' own 9-hour capacity to a full day of combined use. This single figure determines whether the product matches your daily listening duration between access to a power outlet. If your routine demands more continuous runtime without recharging the case, this model will fall short.
