T6 True Wireless Earbuds Bluetooth 5.3 Headphones Touch Cont...

Skip down ~2 paragraphs to get to the review. The first two paragraphs are information about how I conduct my torture tests to determine quality. To ensure fairness and that it isn’t the equipment I’m connected to I’m comparing these to the first pair I received to the second as well as a couple of other earbuds and my Sennheiser headphones. I do not expect these to sound as fabulous as my $130 headphones and neither should you.I’ll start this review by providing information. This is an updated review after having written my original review. I was contacted after my initial review by the company stating that I may have received a defective model and was offered a replacement model at no cost. I have received them and have gone through several rounds of headphone torture tests. While I do not have the equipment to conduct serious tortures nor access to such equipment, namely graphing features and an oscilloscope in order to find out exactly what wave shapes are being produced, I’d like to think that my tests are at least semi valid.I’m conducting my torture with straight rips from CD as well as streaming services. I also use audiocheck.net tests to determine everything that I can’t with just straight listening to music. I use both live and studio versions where available. Here are the songs that I have tortured with. I’ll include notes as well. Keep in mind that I am cross dominant (left handed, left eye, right ear, right foot) so sounds tend to be a little different for me and sounds that I hear that are supposed to be directly in the middle of my head tend to sound stronger on the right channel.REVIEW!!!!!!Outside of quality, which actually did improve with this set,The bass on these earphones is great. The ability to switch at low frequencies and to be able to determine the moment of the switch is well done. Here’s where I get an issue with the bass. On higher quality headphones, you should never hear a whine (unless they’ve been poorly built, just beat to death, or used for quite some time completely unlike what I do here). These headphones produce a buzz when you use the audiocheck “Quality test” which is designed to beat your drivers enough that they shake quite a lot. I don’t fault the makers of these for the buzzing because they are bluetooth earbuds, but I still shouldn’t hear the whining of the drivers begging me to stop the bass test.The mids still aren’t top notch even with the replacement set, but they are certainly better than the previous pair.The highs are fairly well defined, but can muddle at the very top of the range that humans can hear (I have excellent hearing and it’s been determined that I can hear up to 18,000 hz down to 22 hz). When sounds reach that level, that’s pretty rough on headphones and these do pretty well. Do not discount these headphones because of the fact that they muddle at the very top of the human hearing range or right at the bottom, that’s tough to deal with.Overall the replacement pair is far better than the defective model that I originally received. Excellent quality for the price point. They still do not compare to some of the higher quality headsets that I own, but for earbuds they are top notch.—————————————————————————————————————————————This section is all about what I use to test headphones.Before I start the list here is my grading scale for bassFail = Poor quality, extreme difficulty switching between frequencies.Fail = Poor quality or difficulty switching between frequencies with the other being good or greatPass = Great quality at single tone, difficulty with switching between frequencies. IF single tone, great quality.Pass = Great quality, great switching between higher and lower pitch bass soundsBass quality determinationPaper Trails – Darkside (Pass)Magma – Yello (Pass )Pure 30 hz Sine Wave – Binaural Beats Isochronic Tones Lab (should shake loose any earwax buildup. Pass)It’s a Long Way to the Top – AC/DC (Pass They are fully capable of handling the droning bagpipe with the bass guitar. Absolutely passes with this).Falling – Olive (Pass The song is awful, but the bass at the beginning does not disappear like it would on low quality headsets)In this section I’m going on how much trouble I have picking out separate instruments. I should be able to pick out the majority of instruments. If I have trouble then it is a fail. If not, pass.Instrument clarity across all levels (this is unfortunately full of “Your call is very important” hold music)Giant steps – John Coltrane (Pass)Milestones – Miles Davis (Pass)Stella By Starlight – Miles Davis (Pass)Rotation – Herb Alpert (Pass)Flight of the Cosmic Hippo – Bela Fleck and the Flecktones (Pass)King of Swing (live and studio version) – Big Bad Voodoo Daddy (Pass)If there’s muddled sounds and it sounds like things blend together too much then it’s a fail. I’m not trying to pick out first and second chair on an instrument but I should be able to pick out separate instruments.Mid range test (Clarity is extremely important here).King of Swing (live and studio version) – Big Bad Voodoo Daddy (This is a pass, but it’s not an orchestra. 7 piece band though)The Imitation Game – London Symphony Orchestra (Mostly passes. Some trouble picking out strings.)Violin Concerto No. 5 in A Major….. – London Philharmonic Orchestra (LPO) (Pass)Flute Concerto No. 2 in D Major – LPO (Pass)I used a single album for determining whether or not things sound like they are too close together and boxed in. I used Pink Floyd’s Pompeii concert. This single bit has determined both through the remix and the original (which you can stream or if you’re electronically inclined can probably hook up a bluetooth module to a TV with a built in VHS player) that the ability to not sound boxed in is a Pass . Excellent job on managing to do this at this price point, this isn’t something that is exactly easy to do especially over bluetooth or again at this price.
