Our Verdict
Cowin E7 Wireless
TREBLAB Z2 Wireless
The TREBLAB Z2 Wireless are better headphones for mixed usage than the Cowin E7 Wireless. The TREBLAB feel more comfortable and durable, have easier-to-use controls, and support multi-device pairing. Their sound profile is also much better-balanced, with a much more accurate treble range. On the other hand, the Cowin last longer off a single charge and have a slightly better ANC feature, though neither headphones block very much background noise.
