Which is better for commuting and noisy trains?

The Tune Flex 2. Adaptive noise cancelling cuts engine and crowd noise, and Smart Ambient lets you hear announcements. The Tune 235BT has no ANC, so you rely on the earbud seal alone.

Which has better battery life?

The Tune Flex 2 lasts up to 48 hours total with its charging case, though each bud runs a shorter session before a recharge. The Tune 235BT gives up to 25 hours on a single charge with no case needed.

Which is better for calls?

The Tune Flex 2. It uses multiple microphones with call noise reduction, while the Tune 235BT has a single microphone that picks up more background sound.

Hard to say from the data. The Tune Flex 2 has far more owner ratings, which gives a clearer picture of reliability, while the Tune 235BT has only 34 ratings. The neckband design avoids losing a bud, but its cable is the part most likely to wear.

Is the Tune Flex 2 worth stepping up to?

Yes for most people. You gain noise cancelling, spatial audio, personalization, a charging case and better water and dust protection. Step down to the Tune 235BT only if you want physical buttons and a cable you cannot lose.

Which is better for running and workouts?

The Tune Flex 2 has the higher IP54 dust and splash rating and no cable to snag. The Tune 235BT is only IPX4 and its neckband cable can bounce, so it suits light activity better than hard training.
