Back in 2010, he was dismissed from his position as a lecturer at the university. This made him get another job at his friend’s digital marketing company as a blog writer. After a few years, when he was thinking the article writing is his mission, Google pushed the Panda update and affected the company and websites he was working at. (Un)fortunately and surprisingly, he got an offer to head a large knitting factory. In 2016, he got his Ph.D. and resumed teaching at the University … and writing tech-related articles following his passion.

When choosing true wireless Bluetooth earbuds, you should pay attention at only a few features. Of course, we prefer they look amazing. But also, they should comfortably fit in the ear. We would like them to support the latest version of Bluetooth. Also, we want an easier interaction experience. Thus, many things should be done hands-free. But even if it is not so, we shouldn’t do complicated moves and operations on it. At last, the earbuds we are going to buy should be packed with large batteries and provide a long endurance. When I try to combine all these features into one, there are only a few brands I can trust. But I would like to pass the overpriced models of Sony and other giants. Personally, I often prefer brands that make high-quality products and require a sensible price for it. Earlier this year, I got two brand new headphones from iTeknic. After using them for a week, I understand this company is really capable of designing outstanding products. This time I am going to review their newly launched Bluetooth earbuds, namely the iTeknic IK-BH004 Wireless Bluetooth Earbuds.

iTeknic IK-BH004 Wireless Bluetooth Earbuds Design

The appearance of the iTeknic IK-BH004 is not a special topic of conversation. I mean it comes with the high build quality and the materials used in it do not cause any doubts. But there is nothing special the earbuds can boast of. Honestly, no earbuds can boast of a unique design. This is the most painful part for the earbuds manufacturers.

Inside the charging case, we can find LED light that notifies about the charging status of the internal batteries. The 500mAh battery inside the box can charge the two earbuds twice. So you have to keep the case charged and put the earbuds into it every time after using them. Otherwise, one day you will find that there is no power.

As for the earbuds themselves, they have a bit longer tails. But due to the outstanding design, they wouldn’t prevent any of the operations. Also, they won’t fall off from your ears. It’s very comfortable to wear. A 5.8-millimeter driver fits inside each of these earbuds. Noise-canceling microphones eliminate background noise and enhance voice pick-up during phone conversations. Personally, I recommend you to wear them when exercising. Inside the box, you can also find two other pairs of earpads.

Moreover, the iTeknic IK-BH004 Wireless Bluetooth Earbuds are IPX5 waterproof. So exercising under the rain shouldn’t harm them.

As for the interaction with these earbuds, everything is simpler than you think. In fact, the iTeknic IK-BN004 Wireless Bluetooth Earbuds have won Reddot design award 2019. Due to the combined fine design with great functions, it can fight against any top brand.

iTeknic IK-BH004 Wireless Bluetooth Earbuds Connectivity

When pulled from the charging case, the earbuds will pair with each other and then began to search for a device. We tested the iTeknic IK-BH004 Wireless Bluetooth Earbuds with Windows-running computers and Android devices. And we had no problem when connecting. You can connect the device in both mono and stereo mode.

Like all the previous headphones coming our way from iTeknic, these earbuds support Bluetooth 5.0 as well. It’s the latest version of Bluetooth. Due to the enhanced communication features, it is used for multiple devices, such as wireless headphones, wireless keyboards, mice, game controllers, and even for communication between various smart home and Internet of Things (IoT) devices.

However, if you own a smartphone that supports Bluetooth 5.0 and your headphones support the older version, you won’t get any benefit from this friendship. Bluetooth is backward compatible. This means you can continue using your existing Bluetooth 4.2 and older devices with a Bluetooth 5.0 phone. Plus, when you buy new Bluetooth 5.0-enabled accessories, they will work better thanks to the higher version of Bluetooth on your phone.

But this is not the only cool feature of Bluetooth 5.0. Say, it allows you to play audio on two connected devices simultaneously. Usually, I do this when watching movies with my wife. You could even stream two different audio sources to two different audio devices at the same time. This means we can listen to two different pieces of music, but streaming from the same phone.

iTeknic IK-BH004 Wireless Bluetooth Earbuds Advantages

Even on the box of the iTeknic IK-BH004, we can see a special term True Wireless Stereo. TWS is a technology, which allows two audio devices to be paired via Bluetooth. In fact, we have talked about this above. But this is implemented not only due to Bluetooth 5.0 but also to TWS. As separate transmissions can be sent to the left and right earpieces, it permits the reception of a stereo signal.

Moreover, the iTeknic IK-BH004 Wireless Bluetooth Earbuds are equipped with Digital Signal Processing Technology. DSP improves sound quality by tweaking the original signal in several different ways. Particularly, it generates wider frequency output, filters out reverberation, and includes both automatic gain control and dynamic adjustment.

Finally, we should talk about the biggest highlight of iTeknic earphones. It has long-lasting battery life. On a single charge, the earbuds can provide up to 6 hours of operation. And if taking into account the fact that the case can charge them twice, these earbuds can last for 18 hours. Though in some cases, it can last for 25 hours due to the low power-consumption chips, I didn’t have such an experience.

Final Words

It’s unfair to say the iTeknic IK-BH004 Wireless Bluetooth Earbuds offer something that top brands don’t. In this sense, we have reviewed a pair of high-end earbuds that can compete with any brand. Due to the low-power consumption chip, Bluetooth 5.0, optimized touch operations, TWS technology, DSP technology, and a few other features, these earbuds provide a long-lasting and really immersive performance. I was using it when doing fitness. But there are myriads of scenarios you can use them for.


At last, these earbuds cost $54.99. Just search for similar products on the web and compare with the iTeknic earbuds. Most of the results will show overpriced headphones from big manufacturers. But they won’t bring anything that these earphones don’t.

Review of the Iteknic Oral Irrigator——From Walter Shillington

Walter Shillington

Walter Shillington writes about products he is familiar with. His articles focus on healthcare, electronics, watches and household items.

According to a National Health and Nutrition Examination Survey, only 30% of Americans floss daily. That does not surprise me; the few times I’ve crammed one of those thin pieces of fishing line between my teeth, I’d been rewarded with nothing but pain and blood. Since I believe any form of self-inflicted torture to be silly, my attempts to floss were soon abandoned.

But proper dental care is essential. Performed correctly, flossing removes the food particles that stick to teeth, preventing the creation of the bacteria that promotes inflammation and gum disease. Left unchecked, colonies of bacteria (plaque) will harden into tartar, wearing away the gums and bone. This eventually results in tooth loss.

Lately, the health of my teeth has become an issue. A new and fancy sonic toothbrush helped but failed to solve the problem entirely. I decided to try a water flosser. Surely, pulsating water would not hurt near as much as a thin piece of Teflon line?

After checking out several devices, I chose iTeknic’s Oral Irrigator. It appeared to be solidly constructed and was priced at less than half of what I’d paid for my Sonicare toothbrush.


The iTeknic Oral Irrigator is constructed from ABS plastic and weighs 26.6 ounces. It is 5.4 inches wide, 4 inches thick, and slightly less than eight inches tall. This flosser is equipped with a four-foot AC power cord.

Rubber suction cups hold the main unit firmly in place. A front mounted rotary switch turns the flosser on and adjusts water pressure. At the left side, a flexible one-meter hose is connected. It leads to a handheld irrigation tool.

The irrigation tool is fitted with a button which allows quick insertion of the various tips. Water flow can be controlled using a sliding on/off switch.

A 600-milliliter water tank sits directly above the main unit. The tank’s cover consists of a clamshell type storage box containing a variety of spare tips.

Seven water jet tips are included with this system.

Flossing Methods

Those that floss generally use either a thin string or a device much like iTeknic’s Oral Irrigator.

String floss is cheap and can be used practically everywhere. In this process dental floss is inserted between each tooth, gently scraping up and down its surfaces. This removes plaque and food particles from the teeth and out from under the gums. If performed correctly, string flossing is very effective.

Water flossers are not particularly expensive but, because they require electricity and water, are less convenient than string floss. These devices generate pulsating streams of water which massage the gums and push food debris away from teeth. Water flossers tend to be less abusive to the gums than traditional string floss. Also, pulsating water streams can reach areas—especially for those with braces—that dental floss cannot.

Test Procedure

I filled the tank with lukewarm water, plugged in the Oral Irrigator, and inserted a classic jet tip into the irrigation tool. Then I shoved the jet into my mouth and turned the device on.

At this point, I rotated the variable switch to the number two position. The pump rumbled quietly for a moment and then stopped. After I turned on the irrigation tool, a weak stream of water bathed my teeth.

As I continued to rotate the variable switch clockwise, both the water pressure and frequency of pulses rose. At position six, the water stream was comfortable and strong enough to wash away most of the debris stuck between my teeth.

At position eight, the pressure against my gums was no longer quite so comfortable. The pulsating stream of water, however, did a great job of clearing my teeth of debris.

By the time I’d reached position ten on the dial, the pump was on continuously, and both pulse rate and pressure were very high. I found this setting uncomfortable and decide to return to the eight position. For me, this represented the best compromise between efficiency and comfort.

Points to Consider

I initially thought the four-foot power cord to be a bit short. During my tests, however, the length proved to be adequate.

Build quality is excellent, and I expect that both the machine and its accessories will provide yeoman service for several years.

The classic jet tips and tongue cleaner were very effective. I did not use the three specialized tips.

The rotary dial ensures every user can select the most suitable pulse rate/pressure.

To ensure cleanliness, I recommend running a little vinegar through this system once every month.
