Which has better noise canceling?

The Skullcandy Hesh ANC. The 1More SonoFlow Pro has no active noise canceling, so it only blocks sound passively through the earcups.

Which lasts longer on a charge?

The 1More SonoFlow Pro by a wide margin. It runs roughly 70 hours without ANC and about 40 with it on, against up to 22 hours for the Hesh ANC.

Is the Hesh ANC worth stepping up to?

If you fly or commute and need quiet, yes. The ANC and Tile tracker are the main reasons to pick it over the SonoFlow Pro.

Which is more comfortable for long wear?

The SonoFlow Pro is lighter and clamps less. The Hesh ANC has memory foam pads, which some owners prefer, but it is heavier.

Do either work for calls?

Both have built-in mics. The Hesh ANC uses a four-mic array with noise-canceling mics, which generally handles calls better in noisy places.

Can I use either wired?

Both include a 3.5 mm cable for wired listening when the battery runs out.

1More SonoFlow Pro vs Skullcandy Hesh ANC

The 1More SonoFlow Pro is the better pick for long listening sessions and travel, thanks to its larger battery and lighter build. The Skullcandy Hesh ANC wins on noise canceling and features: four-mic ANC, memory foam pads and a built-in Tile tracker. Reviewers praise the SonoFlow line for comfort and battery life; Hesh ANC owners like the ANC and sound but note the short battery life and slow recharge.

Choose the 1More SonoFlow Pro if you want the longest battery life and a light, comfortable over-ear for all-day use.
Choose the Skullcandy Hesh ANC if strong active noise canceling and a Tile tracker matter more to you than battery life.
