Introduction

Bone conduction headphones are different from traditional headphones. Instead of transmitting sound waves through the ear canal to the eardrum, it transmits vibrations directly to the inner ear through the temporal bone. While this offers unique advantages, it also has some disadvantages. In this article, we’ll first discuss common problems with bone conduction headphones, from sound quality to sound leakage. And use the Runner Diver2 Pro as an example to see how it overcomes these issues.

Frequently Asked Questions about Bone Conduction Headphones

Sound Quality

One of the most significant concerns with bone conduction headphones is sound quality. While they excel at delivering mid-range frequencies, they often struggle with low-frequency response. Unlike traditional headphones that can produce rich bass sounds, bone conduction headphones tend to deliver a more muted audio experience. This limitation can be particularly disappointing for audiophiles or those who enjoy bass-heavy music.

Stability issues

Stability can be a concern during physical activities. While they are designed to stay in place, many users find they can slip or shift, detracting from the listening experience. As someone who enjoys outdoor sports, I understand how frustrating it can be when gear doesn’t perform as expected.

Battery Life

Battery life is always a hot topic in the tech world, and bone conduction headphones are no exception. Many models offer limited playtime, which can be a deal-breaker for users who are on the go. Although advancements are being made in battery technology, achieving a longer-lasting battery in a compact design remains elusive.

Sound Leakage

Bone conduction headphones are known for their unique open design, which fits snugly around the outside of the ear, unlike traditional headphones that use sealed ear cups or ear buds. However, this is not the cause of sound leakage. Instead, it is due to the vibration of the headphone core, which causes the surrounding air to vibrate and create sound waves that leak. The leakage is especially noticeable in quiet environments.

Connectivity Issues

Lastly, connectivity can be a stumbling block. Many bone conduction headphones rely on Bluetooth technology, which, while convenient, can sometimes lead to connection instability. Pairing issues and audio dropouts can occur, especially in crowded environments with multiple devices. I know firsthand how disruptive it can be when I’m in the zone, only to be interrupted by technical glitches.

How does the Nank Runner Diver2 Pro solve these problems?

Use the scale function command to process parts of the same shape and different sizes. It provides a lot of convenience for single piece, small batch and multi-variety production and Shortened production cycle.

When using CNC for prototyping, CNC machining methods can be used to program and analyze 3D data. Qualified samples can be made directly using materials such as ABS, PMMA and nylon. CNC prototypes can quickly produce samples with ideal surface quality, especially for large products. After surface spraying, screen printing, and electroplating, prototypes made using CNC prototypes are more attractive than prototypes made with molds. CNC prototypes will become the mainstream of rapid prototyping.

CNC prototype plastic material:
ABS (imported, domestic, black, flame retardant), polyoxymethylene (POM), PMMA (acrylic), PA (nylon), PC, PP and bakelite. Metal materials: aluminum alloy, magnesium alloy, zinc alloy, copper, etc.

Advantages of CNC prototyping:
The advantages of CNC prototypes include high machining speed, low cost and high machining accuracy. A wide selection of materials ensures consistency in materials used for prototyping and mass production. Prototypes made with CNC are closer to real molds and have higher surface quality. After grinding, polishing, sandblasting, painting, screen printing, UV and electroplating, the prototypes and molds made using CNC are completely comparable or even better.

Une petite révolution s’opère aujourd’hui sous la Coupole de l’Académie française. Pour la première fois depuis son existence, l’institution intronise un auteur originaire d’Haïti.

Il siègera dans le fauteuil numéro 2. Celui de Montesquieu. Ce jeudi 28 mai, Windsor Klébert Laferrière, plus connu sous le nom de Dany Laferrière, fera ses premiers pas sous la Coupole de l’Académie française. Pour l’occasion il portera la traditionnelle tenue verte, spécialement confectionnée au Canada en son honneur. Un costume qui a nécessité près de 650 heures de travail selon Ici Radio Canada. Une application méritée. Après tout, ce n’est pas tous les jours qu’un Haïtien intègre le cercle très fermé des immortels. A vrai dire, c’est même la première fois.

Né à Haïti, réfugié à l’âge de 23 ans à Montréal pour fuir les atrocités perpétrées sur sa terre natale par les Tontons macoutes, Dany Laferrière a été élu à l’Académie française en décembre 2013. Une candidature poussée par Hélène Carrère d’Encausse et Jean d’Ormesson qui avoue avoir eu « un coup de foudre » pour l’écrivain. Mardi soir, l’auteur de L’énigme du retour (prix Medicis 1989) se trouvait dans les salons feutrés de l’hôtel de ville de Paris. Face à 400 invités, il a reçu son épée d’académicien des mains de Jean d’Ormesson. Une lame fabriquée à Haïti, sur laquelle est représentée la divinité vaudou Legba.

Forcément attaché à ses racines, Dany Laferrière se compare volontiers aux « peintres haïtiens, capables de peindre des paysages colorés quand tout est désolation autour d’eux ». Pourtant, concernant son rôle au sein de l’Académie, l’auteur explique à France Culture ne pas se présenter comme « le défenseur d’une langue, d’une région, d’une manière d’être. »Selon lui en effet, « la langue est à tout le monde ». Lui qui a un temps travaillé dans les usines de Montréal avant de publier son premier roman, Comment faire l’amour avec un nègre sans se fatiguer (1985), dit aujourd’hui vouloir participer pleinement aux travaux de ses nouveaux confrères, et ce, « jusqu’à la fin! ».
