COBY CV 870 Specifications, Tests and Review

The COBY CV 870 are wireless headphones that allow unrestricted movement and thus increase comfort while listening to music. Because of this feature wireless headphones are especially popular with casual users. On the other hand, the limiting factor of wireless headphones is a certain delay in sound transmission between the source and the headphones (almost indistinguishable for the average user), and they also need to be charged regularly. Unlike wired headphones, where the headphones are charged by the connected cable itself, wireless ones must be charged separately.

These headphones are designed to fit around the ears. Thanks to the design, they can isolate better from external noise than, for example, over-ear headphones. This allows for better listening quality without interference. However, this design tends to make headphones heavier and less practical for frequent carrying

The sound quality can be affected by many factors.
