They are always built after a long listening session in order to form a subjective opinion more objectively) therefore, by the time they appear, they are easy to read by me, sometimes giving rise to constructions from epithets for understanding sound and others. It became interesting how they sound and are there any differences in the measurements? And if you are interested in this – welcome! Unfortunately, the suction effect with such tightly matched nozzles (as in the Ugreen version) also remained here, but fortunately, the life hack of an inveterate IEM-schik was adopted a long time ago – to organize a semblance of an air valve, under the nozzles, interlining and the ears breathe and the nets do not clog at all! Naturally, I immediately began to listen to the whole thing and from the first notes I recognized the handwriting of my first, normal-sounding ws100 – here part of the vocal range is slightly emphasized, but nothing personally resonates in my ear. The specification contains something that I was interested in – "adaptive"… it’s obvious that the form factor of the model partially inherits that of the Ugreen HiTune ws100? … the “ediks” have a slightly more compact package. After opening the lid, I feel deja vu – the case is like a mummy, wrapped in “cellophane” and there is even a bag of silica gel (not everyone puts it) There are only a couple of ear tips and a charging cable on the back of the case, a USB Type-C charging port on the bottom, all the inscriptions (there are no more anywhere else) promise 500 mAh. there is only one red light on the case in the middle, and the lid feels like an egg shell – light and thin – does not inspire the feeling that the Pro version is in the hands … however, the lid is magnetized tightly, it’s hard to object, it slams shut with a confident click the LED in the depth of the holes, they are practically invisible from the depths and apparently, these holes are also needed for microphones , they are held only on the nozzle – it does not cause discomfort In addition to the codec, they promised some cool micro-driver "PU titanium analytical diaphragm distinguishes the difference between frequencies and the human voice in headphones" – as usual, they just sprayed some kind of "na-but" on the dome and presented it as an achievement… at least that’s how I see it in the picture (only I hope that the sound will be no worse than that of 100ok) Hello everyone. Most of the differences are hidden in the abyss of non-linearity, far from ideal converters (microphone capsule – here) and a slightly less dirty sound card path, but even on such a superficial example, the improvements in Adaptive, compared to SBC, are obvious, and which means that hearing is able to detect this when dragged. I decided after a smartphone with "adaptive" to try to connect to an old player with Bluetooth 4.2 and unfortunately, he did not see them either in sbc mode or in aptX mode … he just writes "connection failed" and does not even understand that there is a device nearby ready for pairing – it’s all very strange. The bass is deep, without a pronounced accent, not clipped (like Redmi Buds 3pro), but fast like good shelf speakers, without the booming of slow floorstanders or a cheap subwoofer. I connected to a smartphone, I expected to see aptX Adaptive – it happened (as SoC qcc3040), but I was a little excited that this codec is defined in the Bluetooth Scanner program as LDAC: … I understand that this is most likely an inaccuracy or a program glitch, but still, this cannot but inspire , because if 24/48 is really open here with the possibility of 990kbps (and if they are honest), then this is already something close in quality to Hi-Res and practically not inferior to fashionable LDAC …

Edifier TWS1 Pro headset – introducing aptX Adaptive

The frequency response of the TWS 1 Pro, as I already mentioned, is not unique, it almost exactly repeats the sound signature of the ws100, emphasizing the bass part a little more and moving the high-frequency component away, such a signature does not tire me But about distortions and differences in them for the aptX Adaptive codec and the good old SBC, I was interested to know in more detail, both of them are shown below – a white graph for adaptive, green for SBC … the second harmonic, this is a speaker distortion, the same for both test passes, but in subsequent, pure green already you can observe the differences in the distortions introduced by the codecs – I marked them with an orange arrow both on the THD graph above and on the Intermodulation graph below: Naturally, these are only a small fraction of the differences, only those that I could register after the electromechanical converter (dynamics). I abandoned this case, since my PC with 4.x whistles did not recognize the headset in any way – it is obvious that many owners of old ones will have compatibility problems devices without the 5th generation of the “blue-toothed”, this must be taken into account. If you fit the tips tighter, it becomes a little more bass, the highs recede into the background and do not tend to dominate, but they are there in full (for those who still hear normally) – adaptation to the pitch goes very quickly. Today, we will talk about the almost unremarkable Edifier TWS1 Pro … except for one thing – they are armed with the “aptX Adaptive” codec, the reincarnation / quintessence of the old aptX (LL HD)? I have a few more old-school players with Bluetooth capability – Explorer X1 and Acoustic Research M200 and none of them coped with recognition and connection: even when I switched to SBC mode on my smartphone and a little later completely disconnected from TWS1Pro –
the second one does not see it at all, and the third one is in an endless “active search”) I was not going to buy another TWS at all, but after a very good impression of Neobuds Pro and seeing the very model that I fell in love with at first sight, I ordered it for testing, I wonder what Edifier could do in such a modest budget. in my opinion, TWS1pro is an almost complete copy of the same HiTune ws-100, only with support for the new codec – it was he who became the trigger for the purchase, how much is this story breakthrough? But, as usual, under the ending about graphics I didn’t really plan to refute the application for a speaker, but naturally I didn’t miss the opportunity to look under the “veil” of the grid on the sound guides – there is a microdriver already familiar to me, with a subjectively titanium shade of the dome
