Bests & Worsts Reviews from Amazon

UPDATE 10/27/19 Bottom line: 5 stars for customer service and 1 star for sound quality. When I initially received the buds I wrote a 1 star review which is at the end of this thread. Within 1 day I was contacted by email from their customer service department, asking if I would remove or change my review if they sent me a replacement set, completely free of charge, as I may have received a defective unit. That in itself deserves 5 stars, as it shows the company does want to make their customers happy. However, it also came across as very quid pro quo, as the email mentioned several times, highlighted even, that they wanted me to delete my previous 1 star review for getting a free replacement set. That doesn’t really bother me, as companies like this live or die on amazon reviews and fight for 5 star reviews. It also wasn’t dependent on me changing or deleting my review, they just asked if I would. They were going to send me a free replacement set no matter what because they want every customer to be satisfied. That deserves 5 stars. But here’s the actual problem: the replacement set sounds identical to the first set. The highs are too sharp and the bass clips and distorts even at low volumes. This isn’t a build quality issue, it’s a sound engineering issue. The hardware quality is very solid, they use good drivers and the latest available software/firmware. It’s not a fit issue either. It’s whoever the sound engineer that tuned these and set default or baseline equalization settings that is at fault. The bass frequencies (right around 50-80 hz) are boosted way too high, such that when you listen to anything that hits at that peak (most pop and hip hop), the driver can’t respond fast enough and clips, which results in distortion. The treble range has the same issue, resulting in over powering and sometimes painful sharp and shrill peaks. This problem will persist until the baseline eq is adjusted at the manufacturer, or an option to adjust the eq directly on the set is implemented through firmware upgrades. Until an update to the baseline eq is performed, I cannot recommend this particular set at all, based on sound quality alone. Which is too bad considering the awesome customer service and otherwise outstanding build and feature quality. I wonder now if earlier models of these earbuds suffered from the same sound quality issues or is it just this model. If I was reviewing the company, it would be 5 stars, but I’m not, in reviewing a product, and this product is literally unusable due to the sound. For those of you wondering if I’m just stating personal opinion about my preferred sound settings, this isn’t the same thing as how we like our eq set. No matter what you set your eq at, boosting or lowering certain frequencies, no set should ever distort by default, especially without a way to change it. UPDATE 10/24/19 I was contacted by the customer service department of TOZO regarding the review I left here and they offered to send me a new pair for free because they felt that maybe I received a defective pair. That’s some excellent customer service and deserves at least another star in the review. I also realized that I didn’t give much other information about the product in my first review, as the severely muffled and clipping bass was an absolute deal breaker for me. So here’s a bit more detail about these buds: Pairing was super easy and very fast, literally just take them out of the case and they both find your device and each other. Done. ***** These are in-ear fit that rely on the correct size tip and placement in the ear canal to stay in. There are plenty of tips for you to find the right size so they can stay in place. The tips themselves are silicone and do a good job of sealing the canal to block outside noise and moisture. **** One of the best features of these buds, and my reason for choosing them over the countless other options here on amazon and anywhere else, is the touch controls vs a button that depresses and clicks. For anyone who has used a pair with a physical button you have to push in, you know how uncomfortable and sometimes painful that can be. The touch sensitive controls for these buds is exceptional, having just the right area on the surface that faces away from your ears to activate commands while still leaving the corners not sensitive so you can still adjust them using the sides without accidentally hitting the touch sensitive spots. The controls are simple, quick, and responsive. ***** Battery life and call quality I did not review as I did not have them long enough due to the defective sound quality. I will update this review again when I receive the replacement pair from TOZO. ORIGINAL REVIEW: Sound quality is total garbage, I mean really bad. The bass clips at even low volumes. I’ve never been so disappointed.
