TOZO NC9 ANC Wireless Earbuds

Admittedly, this is my first pair of BT ear buds, coming from a pair of wired Sennheiser ear buds that I still use. I wanted something that would free-up my movements while bicycling and wireless is the way to go! I always read Amazon reviews, and will comment on a few that I've read: 1. TOZO APP: Not sure if other reviews have documented this, but as of my purchase date, the TOZO app DOES support this NC9 model. I decided to download it to adjust the sound. See #3 below. 2. FIT: With the various silicone earcap sizes, I'm somewhat confounded by those who complain about the fit of these earbuds. Mine came stock with one of the smaller sizes (I think it was second smallest) and I ended up moving two sizes up, which is about in the middle of the size selection. I have pretty standard, "normal" sized adult ears. The earbuds stay put very well, and didn't budge when I cut the grass (walking) the other day. I think it's somewhat impractical to expect ANY earbud to stay in place through vigorous movement. 3. SOUND: On first listen, the sound was.....okay. It was decent, but a little on the shrill, glassy side. Good definition and detail, just treble-heavy. This is when I decided to download the app, and to my surprise (and delight) I found that the NC9 was included. I set the EQ to "jazz" (which is a standard EQ setting that I typically enjoy) and it adjusted the sound just fine. Bass extension for a wireless earbud costing $20 was perfectly acceptable. Volume wasn't bad and is adequate. 4. PAIRING: I had zero issues pairing my TOZO earbuds with a couple of phones. Hopefully this will remain the case. 5. CONTROLS: They appear to be pretty standard, though I'd agree that they can be touchy if you get your finger around your ear. I don't mind the voice telling me what mode I'm in. Some people are just......way sensitive to small stuff. I'm not one. 6. BATTERY LIFE: I can't really comment on this yet because I haven't run them dry and re-charged them. I'll update this review as I get more hands-on experience with the battery life. 7. CASE: It's an attractive, little case and the earbuds fit in it very well and very easy to get out. This was a consideration for me, as I was looking at other brands and TOZO models where reviewers expressed some disappointment with the difficulty they had getting the earbuds out of the case. As a lifelong nail-biter, the last thing I need is to struggle catching a teeny, tiny edge of my earbuds so I can release them from their case to use them. You want a good laugh? Watch me try to pick up a dime off a smooth granite or tile floor. 8. NOISE CANCELLATION: Again, being my first set of wireless earbuds, I have no frame of reference as far as a comparison goes, but these seem to be pretty decent at cutting out outside noise. Do they eliminate ALL outside noise? No. For $20 I don't expect them to. They should more than suffice for most human beings who don't carry expectations at the 30,000 foot level. You want a fully noise-cancelling headphone? Buy one. One that covers your entire ear(s). Otherwise, I wouldn't expect 100% noise cancellation. 9. PHONE USE: I didn't buy these to talk on the phone through, I bought them strictly for music listening while bicycling, mowing the lawn, or any other activity that would make wired earbuds inconvenient. For those complaining about how bad phone calls sound? I just laugh. Yes, you're technically supposed to be able to receive calls and speak on the phone. But for $20? Common sense should dictate that if one plans on using BT earbuds primarily for phone work, one is going to want to spend a fair bit more than $20. Get real. 9. VALUE: For $20? Please. Maybe I was lucky in that mine paired easily right out of the box, I was able to adjust the sound easily through the app that now includes this model.......maybe I'm old enough and wise enough not to let expectations run wild on something (ANYTHING) costing $20, but if these last me a year they'll be worth it. Would I buy again? You bet. For the money, the fit and sound are very acceptable.
