Features
- Tackle your pain and inflammation with the power of cold therapy, or turn up the heat to reduce tension and aches. Hyperice X Ambient temperature range is 35F - 115 Hyperice X provides long-lasting, sustained relief without any change in temperature.
- Hyperice X has an adaptive fit that moves with you freely. Enjoy fully automated, electric contrast therapy at home or on-the-go, with no prep, no ice, and no cords. The Hyperice X device may need to be plugged in before first use.
- For best results, place your Hyperice X directly on bare skin. You may wear thin, athletic wear if preferred. Place the Hyperice X over knee and align the kneecap ring with your kneecap. Adjust straps until snug and start your session through the Hyperice App.
- Too big or too small - If the device is too big, use included minimizers by attaching the minimizers to the existing straps and secure. If the device is too small, use the included extenders and attach the extenders in the open loops and secure properly.
- Using the device on the maximum heat or cold setting requires more power and may possibly shorten the battery life during your usage treatment. Please note that you can use your Hyperice X while it's plugged in to the charging power cord.

I bought this when it was on sale over Black Friday. I'm not sure I'd pay full price, but it is very convenient and I love using the alternating hot and cold therapy. It also works much better than the ice machines that pump iced water through a pad. I wish I had had this when I had knee replacement surgery as I would have had to deal with ice and filling the tank with water. The battery life is horrible, but it works just fine while plugged in. Don't expect to get more than a single use out of the device if replying on battery power.

I upgraded from the compression boots to this. I had ran a marathon 2 weeks ago and was experiencing some rad pain in my left knee. I was pushing through my runs when my pain came across when running. I got this device and let me say it has erased my pain within less then 5 hours of having it. The two biggest things I love are the temperature contrast therapy, and the battery life. Shorten your sessions to 15 mins and don’t do the highest or lowest temperature and you will get the most use out of the two. It’s a great device I absolutely recommend for high intensity athletes this is a GAME CHANGER. and so are the compression boots they have! also not so sure about the other knee knee brace they have that’s higher in price but this has been sufficient for me!

This is a great device that does what it advertises. The cold is quite cold and the warm is very warm, if not hot. It is great to have for routine treatment of inflammation or relief after workouts. If you have bad knees (ACL, meniscus tear, arthritis, etc) the ability to sit down and immediately have cold or warm therapy is fantastic. While there is certainly a place for ice and compression devices (I have several) this does the trick for short sessions without the hassle of ice cubes. Is a device that you need? No. But, it is a device that is convenient and works in seconds? Yes! The battery is long enough for several sessions and it is easy to plug in to use if you are out of battery life. There are two downsides: 1) there are 3 sensors in the front that cool or warm your knee so your entire knee (front and back will not be treated) 2) if you have short, thicker legs, the device will be tight. Extension straps are included. Some people have commented that their Hyperice X stopped working after a while. For this reason, I purchased the Amazon extended warranty. A small price for peace of mind. If for some reason I lost this device, I would definitely purchase another one. In fact, I’m thinking about getting a second for my other knee. 😀

The battery life on this is abysmal. It can barely do two routines without shutting down. The app is also lackluster at best. The battery emblem only has full, half, and empty icon so you really never know how much battery you truly have. The cold therapy is neat, but if you do a contrast routine, it will never cool back down to the proper cold level. It’s like it get so hot it can correct back to cold. The hot can be VERY hot, almost burn your skin if you’re not wearing shorts or pants. I just simply can’t recommend this, too many issues. I sent mine back for a return.

Great device for knee injuries! Heat and cold therapy , shortening recovery time. Quite an investment! Worthwhile device, deliver result as expected. Battery charging time need to be improved though! Taking too long to be ready for the next use!

I'm here because MKBHD recommended this device and he's right, the device is amazing. It works well for cold and hot therapy like magic. However, it's nearly ruined by a few major product design decisions that are really hurting it. - No USB C charging, includes another big brick you need to carry around. Please product designers, STOP DOING THIS NONSENSE. You don't need anything other than USB C in 2025. Stop the endless waste. - Most advanced therapy programs require the app, which is mostly terrible to use, requires a login, and wants all your data. Frankly, this should be illegal, I just want to use your product, I don't need to be tracked, and I don't need an account. You can do some basic features through the single button on the device, but good luck remembering the simon says pattern to get there. Smaller thing worth mentioning. It's top heavy, I've seen some marketing that claims you can walk around. I don't see how that would be possible without it continually sliding down. You're not tethered to power, which is great, but I don't think you'll be doing much walking with it on.
