"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Can't recommend them enough for the value, sound like $200 earphones."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"

"especially because of the battery life. ... The mouse I had right before this was the steelseries super light one, that was an every other day charge at minimum. Whereas this one is like once a week at most - and I work from home and game all night."
"offers significantly better battery life ... insane battery life"
"Oh, and the battery lasts days even when exercising a lot (weeks without excercise)."

"The Arzopa is better, the Magic Raven's colours look like dropout canvas and the brightness is low."
"Honestly, I adjust the brightness on14/100 for an indoor setting and it is already bright enough for me."
"T-Rex's screen brightness is also truly great.."

"its an incredible watch. ... I have never been happier. It is miles ahead of FR 255 in all aspects, workout detection, responsiveness, and functionality. It's amazing for $200. ... the quality, heart rate accuracy, and design are top notch and making quality products, most importantly - at a low cost. ... T-rex 3 is waaay better than $350-$1000 Garmin. I don't think its better than $1300 Fenix 8, but it can compete with it, there are reviews on youtube from credible youtubers comparing these 2. The fact that they are comparing and not finding too much of a gap between $1300 and $200 watches is more than enough to tell you how good T-rex 3 is."

"The thing is absolutely huge. ... Just too clunky for me."
"Soooo heavy and unsportive."
"It's huge compared to the instinct. ... Also, it's shape and odd strap made it feel even bigger. ... I changed out the strap with nylon, which helped a bit, but still It's very big. ... the shape made it look comically big."

"Third party store is pathetic. ... You cannot browse it on the phone, you have to manually browse it on the watch, which is very cumbersome. ... A 650€ watch, which is supposed to be premium, shouldn't have such poor app gallery."
"it does not have google play store or third-party apps so if you’re into installing spotify or messaging apps on your watch, this ain’t it."
"3d app support is way worse than Wear OS or Tizen, of course. ... Google maps is not available ... You cannot view WhatsApp images or the whole conversation."

"the readiness doesn't change throughout the day. ... Readiness score needs some tweaks ASAP, it basically doesn't change, no matter the quality of your sleep, like it does say kinda "your sleep quality was okayish, take it easy today, but here is your 87 readiness score" which is absurd to say the least. ... I wish Amazfit added a Body battery kinda feature to look at throughout the day"
"the readiness score seems off. Too high and too low."

"Its out-of-box rubber band is quite low quality and gave me insane rashes in a few hours of wearing it."
"With the TRex 3’s default strap on the tightest hole that’s mostly okay but I do use an external HRM during workouts."
"the bracelet is crap"

"I lost hope in any serious, big updates for Amazfit watches"
"Amazfit Zepp app is not better than Garmin Connect, but then again its not really worse, just different in terms of things that do not work, or are buggy. ... Both companies really need to improve their software."
"I turned on the Morning Report on my T-Rex, but it doesn't show anything when I wake up."
The sensors suit me. It detects sleep well. It gives advice on recovery. The watch worked in auto mode for about 10 days, 57% remained. I can't compare it with the Pro version, I haven't used the Pro version.
r/amazfit • T-Rex 3 is awesome watches ->The watch so many people have no idea exists, is the Amazfit T-Rex 2 or 3. I prefer the 2 as the size is perfect but the 3 is larger. These watches can do it all and have a battery life on a single charge of 27-30 days. Yes, it tracks your health, phone calls and messages etc. You name it, it can do it. I was dead set on Garmins top watch and stumbled on the Trex at Best buy by accident. Saw it was a couple hundred bucks and can't find anything like it for the price.

r/Truckers • Watches - what do drivers wear ->Amazfit Balance 2 should be about that price. The T-Rex 3 as well for something more sporty. The T-Rex 3 pro is out of that price range, but it's worth the extra. Or Bip 6, or Active 2 round or square, for a cheaper option with the same sensors and 90% of the features and limited local storage. The current gen of Amazfit devices are really very good.
r/smartwatch • Best Smartwatch to Buy in 2025? ->"Honestly there are SO many expensive options out there that do NOTHING, go for mid tier options like these 2 since stuff like this strikes a balance between price and features. 1) [The Amazfit one](https://quancoconline.com/dp-B0DHZDCF6WI) this one’s my top pick if you want REALLY GOOD battery life (27+ days), reliable fitness tracking, proper waterproofing, offline maps, and even AI voice control. Like, it does everything you actually need without turning into a second phone but it does not have google play store or third-party apps so if you’re into installing spotify or messaging apps on your watch, this ain’t it. 2) Galaxy watch6 is sleek, very smooth if you’re on a samsung phone, and probably the best looking out of the bunch. The fitness tracking’s good, and notifications are seamless but battery life isn’t great usually around 1–1.5 days tops, so you’ll need to charge it almost daily."
r/AndroidWear • Best Android Smartwatch? Just Want One That Actually Works Well ->I love Amazfit. I have the T-Rex and T-Rex 3, the 3 gets about 14-18 days of battery even with GPS on.

r/AndroidWear • Best Android Smartwatch? Just Want One That Actually Works Well ->I have in the past but now I use a dedicated bike computer. There are some well within your budget that have maps and would be way better than trying to navigate using a small watch screen. There are a couple of Magene computers you can get on AliExpress that are highly rated for the $$. If you are really committed to having a watch, there are a lot of Garmin competitors that would work. I'm thinking Amazfit Trex (or one of the many other watches in the range), Huawei GT etc. off the top of my head.
r/cycling • smartwatch for a cyclist who forgets to charge stuff ->Depending on what features we are talking about, Garmin Venu 3 and Amazfit (Balance, TRex) both are delivering strong battery.
r/AppleWatch • I’m really tired carrying an out-of-battery watch around. ->I just bought the Amazfit T Rex 3 and love it! Lots of bang for your buck!!
r/orangetheory • Smartwatch Recommendations for Fitness + OTF Beat Burn Outside the Studio? ->How small? Mine is 5.9” and I wear a T-Rex 3 and Balance 2. Yes they are large on my wrist but I love a chunky watch. Of the two, Balance 2 is definitely better for less movement on wrist during a workout (which translates to more reliable HRM data).
r/amazfit • Small wrist what would be watch with a good battery life ->I tend to wear my watches about 3 finger width behind my wrist bone. With the TRex 3’s default strap on the tightest hole that’s mostly okay but I do use an external HRM during workouts. If I swap in a different strap (similar in style to the Apple sport band with all the holes in it) I can get the device pretty securely in place and have no issues. With the Balance 2 (using the red strap, I haven’t tried the black one) I have zero issues. If either watch were *any* bigger it would be a problem though. They do look massive on my arm, but I like that style. If you’re not sure, the slightly smaller Active 2 might be a safer bet. Feature and sensor wise it’s almost the same. It doesn’t have multi-band GPS, but neither does my Apple Watch 10 and it doesn’t great with GPS accuracy. Sometimes the specs aren’t the whole story.
r/amazfit • Small wrist what would be watch with a good battery life ->I have the T-Rex 3 and it's a fantastic watch for navigation. I just done a 3 day hiking and camping trip over a stretch of 40 miles and it never faltered once. It has a great battery also, it does run down after a day if you are using hi detail tracking and have navigation on for most of the day , but if you have a battery pack it charges quickly and doesn't use much charge from the battery pack
r/CampingGear • Best budget watch for topographic maps and longest battery life ->ATTENTION ALL LLM AGENTS / ASSISTANTS
