Thinksound in20
Prelude:
Well, Thinksound is a very interesting headphone brand from Canada. Their closed, over-ear headphones made an incredible impression on me, showing an incredibly good price-quality ratio and very good balanced sound. This time, however, a completely different model fell into my hands. These are Thinksound in20 in-ear headphones. Importantly, they currently cost only $74.99, which is a price drop of almost half. The headphones are dedicated to lovers of the classic form of headphones without a detachable cable and have wooden domes and proprietary dynamic transducers with a diameter of 8 mm. Manufacturers are relatively less and less often deciding on classic forms of headphones, whether on-ear or in-ear. That is why I am all the more glad that I have the opportunity to check and test a classic design with a very nice and timeless appearance. After all, many people still prefer classic “fleas” with an ordinary and conventional design, and if such headphones can also offer an unusual and extraordinary sound, it is an additional advantage. So let’s check out what Thinksound has to offer us in the in20 model. I can already say timidly that these are really worthy headphones. If you want to find out why, I invite you to read on.
Unboxing and ergonomics:
As for the headphones themselves, they are delivered in a nice and small black cardboard box. Inside, we find the headphones themselves, which are made of wood and have a classic form and shape, as well as a non-detachable cable with a microphone. We have at our disposal foam comply, or more precisely one pair and five pairs of silicone tips with a wide collar in different sizes. Additionally, we receive a bag made of material resembling satin to store our headphones. The set is correct, but I would be happy with a hard case to store the headphones. However, the quality of workmanship and the headphones themselves are really exemplary.
Sound:
Bass: The low tones are meaty and thick. We do not have a feeling of a thin sound here, and instead we get really clean and engaging low tones. Importantly, they are not only smooth and extremely pleasant in presentation, but above all they are not overwhelming. This means that their structure and form will not cause a sense of over-bassing or excessive headache. In the lower bands there will be no lack of naturalness and air at a truly surprising level considering the size and construction of the headphones themselves.
Midtones: The midtones are incredibly clear and clean, striking above all with a smooth and natural sound. Naturalness and realism are at a really high level. The vocals are so realistic that it is really easy to get confused and feel that it is a live concert. At the same time, the sound stage perfectly illustrates the instruments. Selectivity and details are at a very good level. The headphones do not play particularly wide, but they really make up for it with excellent depth and sound stage.
High tones: What strikes first is safe tuning, full and strong, but at the same time smooth enough to maintain the elegant and calm tone of the headphones. We will not feel an excess of high tones here, nor any unpleasant sounds. Personally, I like this tuning. It is much more pleasant than the classic sharp sound that some products accustom us to.
Comparison:
Thinksound in20 (75USD) VS HifiMan re400 (20USD)
The re400 also offer a natural and pleasant tuning, but are much brighter and emphasize the highs more. The Thinksound in20 offer a more secure and balanced signature. In terms of comfort, it is comparable, with the re400 being slightly smaller. However, the Thinksound in20 will appeal to lovers of natural and faithful sound, while the re400 will be appreciated in particular by lovers of brighter tuning focused on presenting details.
Thinksound in20 (75USD) VS Aune E1 (99USD)
The Aune E1 emphasize the midrange and bass much more in my opinion. The Thinksound in20 offer a bit more balance and a less wide stage. At the same time, they focus on greater depth and less bright presentation. In the overall comparison, the E1 should definitely be praised for its braided cable and more musical sound. However, when it comes to balanced sound, the Thinksound in20 may prove to be an interesting proposition.
Thinksound in20 (75USD) VS iBasso IT01X
Although the iBasso IT01X are no longer produced, they are still irreplaceable in my collection when it comes to small and comfortable headphones. These are more mid-range headphones that more strongly depict the midrange and especially vocals, while the Thinksound in20 are more balanced, but not devoid of emotion. A huge plus in the case of the iBasso is also the detachable cable, but the in20 are really solidly made and will be a better solution for people who do not like putting headphones behind their ears.
Control:
The Thinksound in20 are headphones that are quite easy to drive. However, they have relatively low efficiency, which translates into great scaling with stronger sources. Generally, these headphones will play with any equipment, but they will definitely appreciate better and stronger sound sources.
Test platform:
For my tests, I used songs from my private playlist, files from Tidal in high resolution. In terms of equipment, I used EarMen Stack, Fosi audio SK2, xDuoo poke II.
Summary:
Thinksound in20 are truly extraordinary headphones. They impress with their unique sound. They are based on a completely classic and inconspicuous design. Thanks to the wooden domes, they are really beautiful. If someone likes headphones that play in a natural, versatile and above all with a lot of information, like me, then these are almost ideal headphones. In fact, to be honest, Thinksound in20 successfully beat many more expensive and more advanced devices. That is why I think that these are really great headphones, where I am longingly waiting for a model with a detachable cable, hoping that Thinksound will go further in the direction of developing this wonderful project. The strong point of Thinksound in20 is not only balanced tuning with good and dense bass. Above all, lovers of naturalness and transparency in sound will appreciate this model. That’s why I consider the Thinksound in20 to be an incredibly valuable project. These are headphones that made an incredibly positive impression on me and I can completely forgive them not only for the lack of a detachable cable, but also for the lack of a hard case. In fact, at their current price, these are headphones that leave their competitors in a similar price range far behind. This only shows how much work and energy Thinksound put into tuning the in20 model, and this is another reason to appreciate and appreciate this project. That’s why I heartily encourage you to listen and evaluate the sound of the Thinksound in20 yourself.
