Testing Result
Alright, now let’s dive into some real-time testing results to see how the TOZO T21 Wireless Earbuds perform in various scenarios. I’ve been putting these earbuds through their paces over the past few months, and I’m excited to share my findings with you.
Microphone Testing: T21 has dual-mic noise cancellation. DNS noise cancellation technology clears the call by eliminating the outside noises. I have recorded my voice using the Tozo T21 mic below.
Left Side Microphone (Powerful): After a long investigation, we have found the left side earbud is more powerful than the right side.
Test in the reading room: Yes, It’s perfect for the reading room. I have used it full day and T21 makes me satisfied. Tonal fits ensure the comfort. But the soundproof room is perfect because you can hear a lot of noise around.
AC Room: If the volume is 50% in the AC room, the sound cannot be heard.
Podcast: I have listened to some podcasts and am satisfied, I can give 9 out of 10. the vocal is too much clear.
Bedtime: It’s suitable for bedtime. In testing time I have slept with a sound sleep.
Cycling Time: I tested the buds in cycling time for almost seven days and got no problems. It’s very comfortable. But I do not recommend T21 in cycling time. Because It’s not a snug fit, It’s a tonal fit. If you ride fast and make a hard break it may fall from your ear. Another reason is it protects against outside noises, so if you cycle the road you do not hear the vehicle’s sound, It may occur in any accident. But T21 is perfect which road is not full of vehicles.
Vehicle Horn: Yes, vehicle horns are heard but softly. But if the vehicle is very close, it can be heard quite well.
Shopping mall: Yes, you can use it in the shopping mall. Please try to keep the volume level under 50%. Because at 50% volume, surrounding sounds are not heard.
Gaming: I have played COC and PUBG using T21 earbuds. I feel better than general earbuds.
Raining: Perfect. T21 IPX8 rating, so it’s perfect in the rain. I have tested in the rain and feel good. No, problem with the rain.
Meditation time: No, It’s not perfect for meditation time. For meditation, it is needed to completely block the outside noises, like TOZO HT2.
DB: I have tested MIN. AVG. and MAX. DB by Sound meter apps.
Test Result
| MIN | AVG | MAX |
| 56.8dB | 61.7dB | 75.3dB |
Notice: This measurement is not 100% accurate. It would be best if you thought to decrease or increase the measurement.
You can also personally check by Android apps. Install the sound meter app, play a song, and review the app.
For that reason, we tested three different apps and our sound level was 50%. During the testing time, we played the Ignite (K-391 song) (Alan Walker). See the images below.
Tozo App: Yes, T21 supports Tozo App. I have checked all the features of the apps. See the screenshot below for available features in the apps.
Sound Delay Test: I have also tested a sound delay test. I do not get any abnormal. It’s perfect. You can see the recording video below.
Ringtone: Incoming calls sound another classical ringtone while using T21. The ringtone given on the mobile does not ring.
Classical song testing:
Open Place: I have tested in the open field and lakeside. In this type of place, I have heard a small amount of outside noises.
Comfort with glass: It’s perfect with glass. Not make a single issue. I suggest using it without thinking a bit.
Sweating issues: Tozo T21 IPX8 rating. Sweating does not damage the earbuds. I have tested many times with sweating. Just clean the sweat after using T21, otherwise it may look like old buds.
Wear Comfort: T21 is completely comfortable buds. I have used the buds full day at strength, and I do not get any discomfort. But I suggest please do not use the buds long time because of thinking about your health. I promise you do not feel any bothered wearing the buds full day.
High Volume: T21 makes high volume. Generally, the same amount of volume that an AirPods generates, the T21 generates more volume than that.
Ultra-LightWeight: Yes, T21 is super lightweight. Don’t understand what’s in the ear. Let’s prove it. You do not need to hard work to prove it. Just see the table below.
| Package | With Charging case | Only charging case | Left | Right |
| 101.77 Gram | 46.43 Gram | 38.52 Gram | 3.96 Gram | 3.92 Gram |
Exercise: T21 has an IPX8 rating, I do not get any damage from sweating. But also I have used the buds comfortably.
T-Shirt: Don’t change your t-shirt while wearing earbuds. The earphones are removed from the ears when the t-shirt is opened.
Jogging: Yes. I have also tested while jogging. No problem, use the earbuds without any doubt in the jogging.
Touch Panel Soft than Others: Generally touch panel heart my ear but the T21 touch panel surprises me; It’s too soft. Don’t feel me bothered.
ANC: Manufacturers do not declare about ANC, But we have got the ANC feelings during testing time.
