YOWU Elf Wireless Earphones Review

As an electronics brand, Yowu’s biggest strength has always been fitting audio technology into sleek, playful, aesthetically-pleasing designs aimed at Gen Z consumers. Yowu’s mastery of design is elegantly displayed in its Elf Wireless Earphone (also known as the Sphynx Earphone Series) products.

Compared to Yowu’s signature cat ear headphones, the Elf Wireless Earphones’ design is more graceful and exquisite. Next to the cute aesthetic of cat ears, elf ears have a more mature and ethereal appearance, giving this product a different appeal from most of Yowu’s products. For these reasons, this product will likely be more marketable to fantasy fans who are older than Yowu’s core demographic. Personally, I love these earphones’ design, fit, and light color customization features. 

When it comes to visual appearance, Yowu products have always been a 10/10, but do its technical features hold up to scrutiny? The “elven nest” charging cast is sleek, streamlined, and easy to open. It also provides a hefty amount of battery life. However, my favorite features are the earphones’ dual noise reduction and cutting-edge Bluetooth 5.0 connectivity. The dual noise reduction really boosts the earphones’ sound quality during gaming sessions, wireless phone calls, and music listening parties. The Bluetooth features and LDS antenna also boost these wireless products’ efficiency and stability. If you’re feeling adventurous enough for some real-life questing, the earphones are also water-resistant, so you can live out your woodland elf fantasies by taking them outdoors.

Overall, these earphones are a worthy addition to anyone’s collection. If you want to add a little fantasy to your life, they look fantastic and work great.

Best Gadgets For Traveling

Whether you are going away for the weekend, a month, or even a year, having the right travel gadgets can make your trip more enjoyable. There is no need to break the bank, however. You can get your hands on some must-have gadgets for relatively little money.


A smartphone is probably one of the most useful gadgets you can pack for your travels. It replaces a camera, music player, flashlight, map, and many others. Depending on the model, you might be able to get away with packing just this one item for your trip.

You can get a good budget smartphone for under $200 or spend over $1,000 for some of the newer, high-end devices. Just make sure to get one with enough storage for all your apps and, photos, and videos.


These devices are great for storing books, magazines, movies, and games to enjoy on your trip. You should look into getting one of the larger tablets, however. If your phone has a 6-inch screen, it doesn’t make much sense to go out and buy a tablet with a 7-inch one. You can pick up a 10-inch screen tablet for about $250 today.

Snapchat Spectacles

This is a very unique gadget but it can add some spice to your next trip. These sunglasses from Snapchat allow you to take 10-second clips of your travels and seamlessly post them to Snapchat vi the app on your phone. If you are heavy into social media these are a must-have. And they really do protect your eyes from the sun.

Adding these gadgets to your luggage will ensure a fun and memorable trip, says Dev Randhawa.

Differentiating Physical Vapor Deposition from Chemical Vapor Deposition

Article written by The Digital Terror

PVD and CVD are both reliable techniques utilized in various industries today.

Physical Vapor Deposition (PVD) and Chemical Vapor Deposition (CVD) are two types of deposition techniques that are used to create very thin film layers of a material of choice onto a substrate. Mainly used in the semiconductor production industry, where thin layers are prevalent, both techniques have been making their way into any other industries as well like optics, solar panels, and others. This article will showcase the main differences between the two are the processes that they employ.

As their names imply, PVD utilizes physical forces to deposit while CVD uses chemical reactions. Regardless of the process, both of these techniques produce a thin film in the end.

Physical Vapor Deposition

During the PVD coating process, a source material is gasified through the process of evaporation, the application of electric power, lasers, and other techniques. This evaporated material will then condense onto the substrate, therefore creating the thin film. No chemical reactions occur throughout the process.

Chemical Vapor Deposition

CVD on other hand, uses a source material that is not as pure due to it being mixed with a volatile precursor material. This mixture is then injected within a chamber containing the substrate, where the deposition process occurs, similar to PVD thermal evaporation. Once the mixture adheres to the substrate, the precursor will then decompose, leaving behind a layer of the source material in the substrate. After this, the product is then removed from the chamber through gas flow. This process can also accelerated through the use of plasma, heat, and other processes.

Diamond-Like Carbon Coatings: A Formal Breakdown

A new form of coating technology, diamond like carbon has risen to the ranks to become one of the most highly resistant and resilient type of coating available on the market today.

Diamond like Carbon Properties

The excellent properties of diamond like carbon are what make them stand out from other methods of coating. Boasting an incredibly high wear resistance as well as an extremely low friction coefficient, diamond like carbon applications have been incorporated in a variety of industries such as automotive and oil and gas.

DLC coatings have been known to perform tremendously well under extreme environments that expose the material to high amounts of pressure, abrasive conditions, and volatile interaction. This makes the application of DLC ideal for pipe joints or interior tubing.

DLC coatings have also found a home in the world of medicine. The rising implementation of medical device coatings in invasive procedures has created new leverage on improving a patient’s recovery and sustainability. An example of a medical device coating would be a catheter being inserted into the patient. By applying a coating over the catheter, it will drastically decrease the chance for an infection or even a blood clot from occurring and maximize the safety of the patient.

Methods of Deposition

DLC can be deposited by a variety of methods – chemical vapor deposition, electroplating, flame spray, physical vapor deposition, etc. It should be duly noted that each method has its pros and cons, but these challenges are constantly being met by researchers that are developing new techniques to minimize any risks and issues.

Practical Coating Usage

Coloring steel watches has been a growing industry for some time now. Now, steel is incredibly difficult to recolor. Not only will natural methods come off with wear, but the quality will just lack in the end.

For optimal coating, there are two processes that are utilized: physical vapor deposition and diamond like carbon. Both processes do the job but DLC utilizes the properties of carbon to create a smooth and extremely tough end result. It’s been known that PVD wears off after years of usage – these are just based on opinions.

As mentioned before, DLC coating’s properties make them useful for watches – the abuse that they take unknowingly throughout the day is far more rugged than you might realize. Abrasion and water resistance are two of the more common properties that watches need to survive on a day-to-day basis. DLC coatings are essentially a versatile protective shell that is built to last.
