Embr Wave 1 vs 2 (2022): How About Wearing A Thermostat On Your Wrist?

When it’s too hot or too cold, the first thing we do is run to the thermostat and adjust the settings. But what if you can feel warmer or cooler by just wearing something on the wrist? This is what Embr Labs promises with the Wave, an intelligent wristband designed to trick your brain into thinking you’re warmer or cooler than you are.

The company released the first-generation Embr Wave back in 2017. Owing to its success and therapeutic benefits, Embr Labs launched the Embr Wave 2 in April 2021. The second-gen wearable improves the features of the Wave 1 and comes with a sleeker design.

The Embr Wave 2 offers a design refinement from the bulky original Wave.

The Embr Wave 1 and Wave 2 are personal and portable thermostats you can wear on your wrist like a luxury watch. Unlike most thermostats, these intelligent wristbands look sleek. It helps that both come with stainless steel Milanese loop bands for a dress watch aesthetic.

However, one of the main gripes about the Embr Wave 1 is its size. At 52mm long and 29mm wide, it’s especially large for those with smaller wrists. For comparison, the Apple Watch 7’s biggest model measures 45mm.

The original Wave also comes with a light bar for adjusting the temperature levels of the band, glowing red for warming and blue for cooling. While it looks futuristic, it doesn’t offer tactile feedback. It’s also easy to accidentally press either side of the bar.

On the other hand, the Embr Wave 2 was launched with a redesigned form, incorporating consumer feedback. Instead of a rectangular module, you’re getting a round case 44mm in diameter. This brings it closer to most smartwatch dimensions.

The Embr Wave 2 also replaces the original Wave’s light bar with two physical buttons and small indicator lights. Placed on the side, you can adjust temperature levels more discreetly, especially if they’re not using the mobile app.

Embr’s original Wave comes in Silver and Rose Gold variants. Meanwhile, the Embr Wave 2 is available in Black and Rose Gold. Keep in mind that these are not waterproof wearables. While they are water-resistant, you can’t submerge these devices.

Technology and Features

The Embr Wave 1 and Wave 2 deliver precisely engineered cooling or warming thermal waves to your wrist to provide immediate relief.

How can a wearable make you feel cool or warm? The secret lies in where you place the Embr Wave. See, these wristbands don’t change your body temperature. Instead, it tricks your mind to think you’re experiencing a more comfortable temperature. Underneath Wave 1 and Wave 2 is a cooling/warming plate. Here, cooling or warming thermal waves are delivered to your inner wrist.

Because this part of the body has temperature-sensitive skin, the temperature sensations emitted by the Wave stimulate thermoregulation in your brain. Have you noticed how simply holding a cup of coffee can make you feel warm? Have you dipped your toes in cold water to help you cool down? The Embr Wave 1 and Wave 2 work similarly.

But how do you operate these wearables? As mentioned in the Design section, the Wave 1 and Wave 2 have onboard controls. However, you can do more by connecting the bands to their respective mobile apps. Through their apps, you can adjust the level of cooling or warming you need, along with the intensity or the duration of a session.

Users can also select from different modes. These preset profiles relieve specific concerns like hot flashes or sleeplessness. Meanwhile, some help you relax or cool down. If you’re not feeling any of them, you can customize your session. Embr’s mobile apps also track your usage and help you discover patterns.

Pricing, Battery Life, and Accessories

The Embr Wave 2 costs more than the Embr Wave 1. It also has longer battery life. However, both devices are almost equal when it comes to compatible accessories.

Since the launch of the Embr Wave 2, the original model has been hard to come by. You may still find online stores offering it, but stocks are limited. The Embr Wave 1 originally retailed for around $299, but discounted rates should be available.

In contrast, the Embr Wave 2’s original price is $349. Compared to other wearables, it’s on the expensive side. Fortunately, interest-free installments via Shop Pay are available.

Embr Labs isn’t specific when it comes to battery life the way smartwatches are. For instance, you don’t get how many hours of use the Wave 1 offers. Instead, Embr shares that the band can be used intermittently for two to three days for up to 50 sessions. If you frequently cool or warm yourself, you will probably get 10 or fewer sessions.

On the other hand, the Wave 2’s battery life depends on the modes you use. For cooling Hot Flashes, you get 3 to 5 hours of operating time. If you’re simply trying to cool down, you get up to 15 hours of use. You can also use the Wave 2 overnight with the Stay Asleep Cooling or Warming modes. Again, these numbers will vary depending on personal settings.

As for accessories, Embr Labs offers several. Among the more popular items include the travel case for the Embr Wave 2. If you’re not a fan of metal straps, the company offers nylon comfort and vegan leather bands, too. Similar options are available for the original Wave.


The Embr Wave 2 is a better wristband than the original Wave, offering design improvements that refine its technology.

Embr Labs is one of several companies pushing the envelope for what wearables can do. Like InteraXon’s Muse, Embr’s wristbands target a niche of the wellness industry.

The Embr Wave 1 introduced the ability to cool or warm yourself using a wristband. With the Ember Wave 2, the design and functionality of the device have been further refined. This gives the second-gen wristband a decisive advantage over the original.

But do you need it? Well, we’ve all been there. You’re feeling warm, and he’s feeling cool. Or, an office’s ambient temperature just doesn’t work for you. A discreet device like the Embr Wave, especially the latest iteration, offers a discreet way of getting comfort and relief without messing around with the thermostat.

Women struggling with hot flashes also stand to benefit from the Wave. This lends credence to wearables not just being a fad but a tool for holistic living.


📌 What’s the main difference between the Embr Wave 1 and Wave 2?

The Embr Wave 2 has a circular case as opposed to the rectangular module of the Embr Wave 1. Embr’s Wave 2 also adds more modes and improves upon the original’s battery life.

📌 Is the Embr Wave worth it?

If you’re someone suffering from hot flashes, the Embr Wave is worth buying. It’s an effective tool for getting comfort and relief and it works discreetly.

📌 Does the Embr Wave 2 come with a USB port or wall plug?

No. The Embr Wave 2 does not come with a power brick. You will need to find a USB port to connect the magnetic charger.

📌 How long is the warranty of the Embr Wave?

The Embr Wave comes with a limited one-year warranty.
