While TalkThru lets you stop for a quick chat without having to remove your headphones.

In testing, they cut back low-frequency rumble as you hear on an airplane with ease, but they didn’t fare as well against a recording of a busy restaurant with clanging dishes and boisterous conversation. In the second test, the high-mids and highs easily bypassed the ANC circuitry. Ultimately, the performance here is about what you would expect for the price, and we’re at least happy to report that the ANC doesn’t seem to impact the audio performance.

The Tune Flex is equipped with 4 microphones, so you’ll always be heard with perfect clarity. Just enjoy hassle-free, hands-free calls in stereo. Also, never hesitate to take or make a call again.

If you’re in hurry, then with Speed charge, you will get 2 hours of playtime with just 10 minutes of charge. These make the earbuds of premium quality. However, on regular basis, you will get lesser than 6 hours of battery. Overall, the earbuds have a complete package of battery life and you will never be upset with the battery if you want to buy this one.
