Bests & Worsts Reviews from Amazon

I have had my earbuds for about 4 months now. I am a highly technical person, and I love music, but do not think I would classify myself as an audiophile. I now have 3 different sets of TWS earbuds, and out of the 3, these are my favorites. One thing I did that makes a difference, at least for me, is I replaced the included tips with memory foam ones that I have used on a number of different earbuds over the past few years. Pros: Good sound quality Good bass, especially with replacement tips Good battery life Rapid charging Wireless case charging Solid build feel Good customer service Cons Stiff buttons Intermittent connection loss Sound/Bass: These sound as good as any other headphones I have used over the past 5 years or so. I do not spend the money for high-end brands like Bose or Beats, so I can't really compare these to them. I was able to hear a full range of frequencies and there was good clarity. With replacement memory foam tips, the noise isolation is good enough to block out 75% or more of my 20-year old lawnmower's engine. Battery Life I have researched and used enough of these to realize that I am not going to go 9-20 hours without having to change the buds. That said, even at high volume levels, the battery life on the buds exceeds what I expected. I can get from 2.5-3 hours on full volume, usually, and longer if I am not playing music/audio books the entire time. They charge pretty quickly in the case too, which means minimal downtime if you need to charge them up. I particularly love the wireless charging for the case. At night, I can just drop it on a charging pad next to bed, and well before morning, the case and buds are at full charge. Between the buds and the case, I am able to go all day without having to recharge the case. Build The buds and the case have a solid feel to them and have held up well. The case, in particular, is solid and has survived my pants pocket and laptop bag admirably. Another brand that I purchased, the cover broke off the case within 2 months. Customer Service I have had to reach out to TOZO twice about my buds. The first time, was due to intermittent loss of connection, the second, when my right earbud died. I received responses in a reasonable amount of time (usually, overnight), and there was no hassle dealing with them. Stiff Buttons I find the buttons are a bit stiff on the buds, and when I press them, I sometimes feel like I am forcing the bud deeper/too deep into my ear canal. It is not a huge issue, but if you push at the wrong angle, it can be a little uncomfortable. Intermittent Connectivity This is probably the only, and biggest, issue I encountered. All TWS buds that I have encountered, and even bluetooth headphones such as the Leophile Eel and LG Tone (any version) can lose connectivity. What I found is that there are a couple of places where the buds regularly get disrupted for some reason. I realize it must be the concentration of wireless/bluetooth signal, but it is inconvenient. It has never reached a point where I felt I needed to go out and buy a different pair to resolve the issue. My other TWS earbuds are the Enacfire E19 and Enacfire E20. As much as I like the E19, these are just enough better for me to move them to the "backup" set. I just got the E20, and the shape/size of them is odd enough that I am not sure that I can enjoy them. Compared to either, the TOZO buds win.
