The Koss BT740iQZ Active Noise Cancelling Wireless Headphone have received mixed reviews from users online. By analyzing what buyers have liked and disliked about these wireless ANC headphones, we can get a balanced perspective on their real-world performance.

The Positives

Firstly, many users praise the Koss BT740iQZ Active Noise Cancelling Wireless Headphone for their stellar battery life. The 30+ hours of runtime per charge far exceeds that of comparable wireless ANC headphones, making them great for long trips. Users confirm they can go days without recharging.

Secondly, owners compliment the capable active noise cancelling that significantly reduces ambient sound in noisy environments like airplane cabins or busy offices. The ANC allows for undisturbed music listening and call clarity.

Users also appreciate the intuitive onboard controls which allow easy management of volume, tracks, calls and ANC modes. The buttons provide convenient hands-free control.

In terms of sound quality, users describe the audio output as decent enough for casual listening, with punchy bass and clear mids. The overall balanced sound profile suits genres from EDM to jazz.

Buyers also like the foldable design that makes the headphones easy to pack along in bags. The inclusion of a carrying pouch adds to the portability.

The Negatives

Now coming to the downsides reported by some users, the biggest complaint is about the outdated micro-USB charging port instead of the more modern USB-C. Many question this baffling choice in 2023.

While not a deal breaker, some users do feel the plastic build looks a bit cheap and lacks the premium styling and refinement of more expensive brands. The plain design doesn’t scream high-end.

Comfort is another aspect where users are divided. Some find the earcups too snug and complain about discomfort over long listening sessions. Those with larger ear sizes especially report issues with fit.

Finally, a minority of users face connectivity problems like audio dropouts when paired with certain phones. However, this seems device dependent.
