Design and features:This Bluetooth wireless portable bone conduction model provides acceptable sound. Its open-air design doesn't muffle outside sounds so you'll be able to hear that door bell ring, train announcement, or car horn when you are wearing the headphones.
Additional features include:
Has integrated volume control, microphone, and call connect/disconnect control. Has 4 EQ settings, standard, vocal, bass boost, treble boost. Free Shokz app download for iOS and Android mobile devices adds additional features and software updates.
Sound quality:We found the OpenRun Pro 2 delivers sound quality that falls in the acceptable range - it reproduces music and voice reasonably well despite the obvious shortcomings in its sound. This model has four tone settings; the Standard tone setting was used. The bass (as in bass drums, bass guitars, stand-up bass, etc.) has decent impact but is a bit boomy and deep bass is lacking. The midrange (voices, guitars, horns, etc.) is somewhat congested (think sonic traffic jam) and a bit muffled, grainy, thin and somewhat nasal and a touch sibilant. The treble (cymbals, the upper range of violins, etc.) lacked extension depending on fit where proximity to the ear canal can effect perception of treble and was a bit subdued, smeared and sizzly (sounds that should have a delicate shimmer have a sound reminiscent of bacon frying). The sound also has a decent sense of liveliness but does a so-so job of recovering room ambience from recordings. It has an open sound, but that's because it's not covering your ears, not because the audio sounds open. Warmish character. The overall sound can be summarized as somewhat congested and a bit muffled and grainy. The other tone setting had a noticeable effect on the sound. Note: Classic mode has the "electric shock-like" vibration effect where it makes contact with the sides of the face.
Comfort and Fit:Users with small to medium sized heads will probably find that they produce a slight sense of pressure in front of the ears.
Small
Users with small sized heads will probably find that the neckband is generally not noticeable unless it interferes with clothing, hair, headwear, especially if the users lift their heads such as when looking up.
Large
Users with larger heads may find they produce a significant sense of pressure in front of the ears and may actually pull back on the front of the ears uncomfortably, especially if the users lift their heads such as when looking up but slightly less so versus the OpenRun Pro 2 Mini.
Fits securely even with vigorous head movement.
Users with larger heads may find that the neckband makes contact with the back if their heads or necks, especially when they lift their heads such as when looking up.
Classic EQ
Unlike similar models no "shock-like" vibration is felt except in the "Classic" EQ preset mode a vibration can be felt that might feel like an electric shock (but it's not).
