Best Openear buds hands down!
I have tried so many of these open earbuds, but they either have a very weak sound or don't fit right. This is an exception, and they sound better than in-ear earbuds. They are very comfortable and stable and work excellent for running and workouts - highly recommended!

Sounds great but stopped charging
I bought this on Feb 2024 and I was happy with the sound quality and comfort. After few months one of the charging pins got stuck maybe because of the sweat after I put it inside the case. I had to buy new case and used it till Aug then one of the headset stopped charging.

Sound is very good despite background noises but
But the mic is very weak it barely picks up my voice. If you want to hear music or podcasts then this is for you. But for work? I do not recommend it!

I have purchased 2 pairs of these headphones. I thought I had lost the first set, and decided to purchase them again base d on the overall performance. I had purchased the black color (same style as the second pair) originally, but decided to go with the blue pair the second purchase. My notion was, if I happen to find the black pair ( I did happen to find them) I could differenciate the sets by color. I usually wear one at work because I am required to hear people and noises around me. They function very well with only one being utilized at a time, but I would say you do have to trade all functionality for finger to headphone operation. Flaws: The left side turns the volume down, the right has volume up function. The left side adujusts songs back to previous song, the right jumps to the next song. Other functions correlate with the same premise. I would like to adjust the functionality by assigning them to my preference and style of listening. I downloaded the app in hopes I could do something like this. I am not. In fact, the headphones tout you may adjust the equalizer within the app. The truth is, I downloaded the app, but was unsuccessful with using the equalizer at all. Every attempt I made to assign the equalizer was repeatedly received with the message stating "device not compatible." Note: the options from other users for equalizer settings was available, but when attempting to assign, I received the message as stated above Another problem with the app is preset specific equalizers for music, speech, instrumental, etc... were not options. The only way to get equalizers was to utilize the settings other app users presented, or to develop your own. I don't have the time, ear, or knowledge of equalizer/soundwaives to do all of that. I know basics like Hip Hope uses a lot of bass, Heavy Metal, more treble, my basic knowledge is not good enough for my personal devlopment. Future App Development, AKA App developer: I just want to pick Jazz, or Audio book, or Classical/Instrumental equalizers and the like by selecting a preset. Positives: Headphones sound exellent with the regular equalizer settings. Waterproof (I accidentally wore them in the shower) but must advise not to put wet earphones in the case-charger. I like the ability to adjust the earphones in and out, up and down. The earphones are comfortable. The black and blue colored ones are gender neutral. The case holds a 40 hour charge, and the earphones will sustain 12 hours of continual use. I usually listen with them for around 8 hours while I work. The connection within the charging case is wonderful. The Bluetooth connection is easy and is listed as Tozo. Once they are connected, within Bluetooth a message expains device is paired to phone, and music. While using only one headphone, I am able to answer my phone, and disconnect. I can also hear when notifications like texts arrive. I don't often check my phone, hear, or feel vibration when I receive a text and it may take a whole day before I discover I received one. The phone helps me check the phone more often, when I may be needed. I really like how easy pressing the earphones is. I often have to touch them to pause my amazon music stream while I interact with other people at work. One touch, pauses the thing and another unpauses. When I wear them while mowing my lawn or tilling, I can hear the music while the motor noise is diminished substanially. I love that. Overall: I wish I could program the functions into each headphone. Standard Equalizer needs to offer professional manufuactured options (not only other users equalizer preferences and development. You really have to listen to a lot with the music you enjoy to find one that works. Too much work in my opinion. Was unable to connect the headphones to even another users equalizer offerings. I really like these.

Davvero comodi, la musica e l'audio delle chiamate si sentono benissimo e si collegano allo smartphone rapidamente ed in automatico; oltretutto supportano due connessioni contemporanee (solo una in ascolto per volta però). Consiglio anche perchè ti permettono di parlare con le persone vicine anche se ascolti musica, senza necessità di toglierli.
