These T20 earbuds are the second Tozo earbuds I've purchased, and my fourth pair overall. As a value-conscious consumer, I've only purchased earbuds in the sub-$40 price range so far. Tozo T6s, Wyze Buds, Anker Soundcore P3i, and these Tozo T20s.I've attached a few pictures of the outside of the box, the components when unboxing, and a picture of one of the pages of the user manual that comes with the earbuds describing the specs and the "touch area" for the controls (sorry about the crappy lighting).The good:*The price/value - This is very important to me.*USB-C Charging - I really like my Tozo T6s, but the mini-USB on the bottom of the case was a pain. The T20s improve on that with a USB-C port on the back of the case.*The battery / charge display on the case - Another point I really like is the display on the case. When flipping the lid up or down, the display on the case provides clear visual feedback on the state of battery for the case itself, as well as the each of the earbuds when they are charging the the case. The Tozo T6s have multiple LEDs on the case to indicate charge (good), but the Wyze and P3i's only have single LEDs to indicate if it's charging or not, but no clear way to know if it's 20%, 45%, 80%? I never knew how much I appreciated the T6 display until I tried the other earbuds and now the T20 display is EVEN BETTER.*IPX6 rating - Granted, I haven't used these in the shower or underwater or out for my runs yet, but I do like that they're waterproof and sweatproof. I sweat a lot when I run so if, one: I can get these to stay in my ear, and two: they don't succumb to my sweat, I'll be happy.*Mono listening - It's important to me that I can use the left, or right, or both earbuds. Often I only have one earbud in so I don't want earbuds that require you to keep both out of the case just to use them (Yes, some force you to do this. Why? I don't know)The bad:*Pause upon removal - All my other buds will autopause my media if I remove an earbud. These T20s don't. I hope that can be updated in the App or something, because I really like my podcasts to autopause when I have to pull my earbuds out because my wife or kids need my attention.(Update 2023/09/24) - This seems to be intermittent. It didn't work on my computer, but it worked on my phone, which leads me to believe that the earbuds are designed for this, but the in/out-of-ear detection may just be a bit flawed.*These earbuds are NOT for audiophiles. For my usage - YouTube, podcasts, some gaming, and music, these are fine. If you're capable of discerning that the 22Hz bass note is really supposed to be 24Hz in this song, then you probably need more fidelity than these sub $40 earbuds can provide.*Form factor - I'm still partial to the Tozo T6s form. It's really just a personal preference. I've figured out that I prefer the earbuds without the kickstand that comes out of the ear.*Touch area (see picture) - it's small, near the top of the buds, and doesn't really provide any tactile feedback that "here's where to need to press". Again, personal preference. I prefer the T6s or the P3i's (if you like the kickstand form factor) because the P3i's tactile area is basically anywhere on the whole kickstand part.The OK / fine / "this just 'is' " features / operation:*Bluetooth pairing & first use - I was able to pair these buds up to my computer without issue. Some of the other buds say "Connecting" or "Pairing" or make some unique startup sound upon first use or when they don't have a connection, but I didn't hear anything out of the T20s.*Controls - I'm not sure if I can change the button presses in the Tozo App, some earbuds have that feature but I haven't downloaded the App yet. The volume, pause, and next/previous track controls do work as described in the included manual, though I noticed that on my computer that the Volume+ and Volume- were in increments of 5, i.e. once I paired them to my computer and set my volume to "48" in Windows, the Vol+ went to 53 then 58 then 63...same thing on the way back down. I did not have a chance to test the voice assistant or phone call controls yet.*App - haven't tried it yet, but out of the box the earbuds work. Small tweaks / customizations I would make in the app would be changes to the actions for what button presses do, options to pause media when the earbuds are removed.(Update 2023-09-24) - Not quite sure why the app is 80+MB, but it does have some sample music tracks, allows you to tweak the EQ on these T20s, and allows you to reconfigure the button presses. It prompts you to signup for a Tozo account, but it allows you to skip it as well. It is good that Tozo does NOT require an account to using the app, though it's clear from the UI design that a Tozo account is heavily encouraged.*Dings - As I write this review, I have other media paused in the background. About every 10-15mins or so, the left earbuds is sending a chime. Yes, just the left one. I don't know if this is to indicate "Hey, I'm still on, using battery, connected to your computer" or a "Disconnect/Reconnect" event or what this chime means.Things that I haven't really had a chance to test, but will report back if/when I do:*Phone Audio Quality - I have a loud coworker that I take conference calls next to. When using the T6s, I get complaints from colleagues that they can hear him. I'm going to try these T20s to see if the microphone is better in background noise reduction.*Noise cancelling - I wouldn't hang my hat on this feature. I'm sure it's there, but if you've ever had a chance to use legitimate noise cancelling headphones, these won't hold a candle to those. Generally though, if you size your ear tips correctly (Tozo provides a few different sizes with the buds), then they do a good job isolating noise.*Battery Life - Not sure how long these will last, but if they're anything like the T6s, I'm pretty happy with how long the battery goes, and how quick it charges.Would I recommend?Yes! If you're looking for some functional earbuds that won't break the bank, I'd give these Tozo buds a chance to see if they're a fit for you.
