Bass & Sub Bass

Bass of the 1MORE SonoFlow responds with a massively fun sound that will even rumble and rattle the ears a bit.

Both mid bass and sub bass offer a balanced distribution that is both very punchy and able to extend to the deepest sub notes without showing any drastic rolling off.

Despite the very strong bass response, this 1MORE headphones did not overcook it, as they do not sound as bouncy nor loose as other bass-intense headphones on the market.

Therefore, allowing them to cover a wider gamut of music styles and not limiting to bass-only tracks.

Mids & Vocals

The SonoFlow offers a rich mid and male vocals flavor with a warm and cozy feel to them.

Lower mids and deep pitched vocals will provide a full, rounded sound that can offer an intimate and agreeable listening session while not becoming overly congested despite some perceivable mid bass bleed.

Upper mids respond with a crispier and less busy sound that still is smooth and harsh-free at all times.

Overall, the midrange of the 1MORE SonoFlow will offer a pleasant and non-disturbing tuning for a wide variety of genres and long listening sessions.



Highs & Treble

Highs on the SonoFlow inherit a coherent tuning as their lows and mids, providing a smooth and non-fatiguing experience on any genre.

On the other hand, these ranges will show a more evident darkish tint over them but not as much as to be rated as muddy nor dark highs.

The highs of this headphones will adapt very well to listeners that look for a gentle, mellow highs tuning over an analytical and fatiguing one.

Sound Isolation

The SonoFlow offers a stronger passive isolation than most over ear headphones almost seeming like having ANC already turned On.

This sets a perfect boosting playground for its QuietMax Active Noise Cancelling, allowing it to reach a massive noise reduction that vastly surpasses any normal headphone with ANC.

In addition to this, the headphones comes with a Pass-through mode that showed, also, a very good performance boosting surrounding noises and awareness without sounding awkward or disturbing.

The 1MORE SonoFlow truly excel in the comfort department due to their generous padding, quality earmuffs materials, light weight (despite a reinforced metal headband frame) and the right amount of clamping force.

Moreover, the earcups can be tilted and rotated to adapt to any user and can also be fully rotated and collapsed for transporting and storing.

On top of that, the headphone is equipped with 4 physical buttons that can cover all main functions in a more intuitive way than headphones with a single multifunction button.
