Hi-Fi, often mentioned in audiophile circles, is actually an abbreviation of English high-Fidelity, Chinese meaning "high fidelity", referring to playback audio that is very similar to the original sound. At the beginning of the popularity of the concept of Hi-Fi, people generally tended to use large audio equipment to play high-quality audio files for a better experience. However, with the miniaturization and continuous development of high-end audio components, the headphones launched by many audio manufacturers have also begun to take the Hi-Fi route. Today, I want to introduce the CKR7TW true wireless headphones from the old Japanese audio factory Iron Triangle, which has incorporated a lot of HiFi thinking into the design and tuning. So how the Iron Triangle CKR7TW performs, please listen to me for you to explain in detail.
First look at the appearance, unlike most of the true wireless Bluetooth headsets on the market with rounded design, the iron triangle CKR7TW has chosen a particularly unique route, and the stepped design on the outside of the headphones is eye-catching, which highlights the classic brand LOGO of the iron triangle. In order to enhance the stability of the headphones, the Iron Triangle KRR7TW comes with a pair of 3D shark fin sports collars that can better fit the human ear and fit the ear contour. I tried to do warm-up exercises and jogging with the Iron Triangle CKR7TW, and the headphones were very firm throughout the process, without a hint of falling off.
The iron triangle CKR7TW fuselage adopts an ergonomic design as a whole, which can fit the human ear very well, and even after wearing it for a long time, it will not bring obvious pressure and is very comfortable. This has to mention that the weight of the unilateral side of this headset is compressed to the extreme of 9g, and the light body weakens the foreign body caused by its wearing, and does not make the wearer feel tired. It is worth mentioning that the charging case of the iron triangle CKR7TW also weighs only 68g, which makes this headset very suitable for our daily use.
Having said the look and feel, let's return to the sound quality of the Iron Triangle CKR7TW. The iron triangle CKR7TW has built-in an exclusive design 11mm sound unit, and the DLC drill carbon fiber layer diaphragm has the characteristics of refining high frequencies. The headphone suppression ring is made of brass, which can effectively reduce resonance and improve the stability of the audio. The back end of the headphone body is equipped with the AKM AK4375 low-noise speaker-level DAC chip, which can reduce distortion and improve audio resolution. This is the reason why the iron triangle CKR7TW is a true wireless Bluetooth headset built with HiFi thinking.
In addition to excellent audio hardware, Iron Triangle has also put considerable effort into the software level of the CKR7TW. In order to ensure the sound quality when music is played, as well as the stability of audio propagation, the Iron Triangle CKR7TW applies the popular Bluetooth 5.0 connection technology. AptX and AAC audio decoding under Bluetooth 5.0 make the Iron Triangle CKR7TW have higher quality resolution than other similar products.
In the specific music playback, thanks to the application of DLC coated diaphragm, which is very common on high-end iron triangle headphones, and equipped with a dedicated DAC chip, I have to say that the iron triangle CKR7TW exceeds my assumptions about the sound quality of a true wireless Bluetooth headset. The iron triangle CKR7TW has a particularly good performance of medium and high frequencies and high frequencies, and the vocals are clear and pure. Especially when playing some high-quality audio files, coupled with Qualcomm's aptX decoding, the advantages of the CKR7TW are very obvious.
Many people choose true wireless headphones to wear for a long time, convenient to answer calls at any time, listen to voice messages or play media, so in addition to comfortable wearing, convenient and fast operation is equally important for true wireless headphones. Iron Triangle CKR7TW has a side key on both sides, through clicking, double-clicking, three-click can easily achieve play/pause media, switch songs and adjust the volume, you can touch the button with a touch, even if you are new to the real wireless headphones can quickly adapt to the operation logic of the Iron Triangle CKR7TW.
In terms of battery life, although the iron triangle CKR7TW can not be said to be average, it has also reached the level that the true wireless Bluetooth headset should reach. When used alone, the headphones last for 6 hours, and can reach 15 hours when combined with the charging case. People like me, who just take out their headphones to listen to music when they commute to work every day, and use them lightly, probably need to charge the charging case of the headphones every two or three days. If it is like a continuous brush drama in the leisure time of the weekend, it may be necessary to put the headphones in the charging case to return the blood after a morning.
Overall, the Iron Triangle CKR7TW is indeed a powerful true wireless Bluetooth headset. The sleek look, lightweight and ergonomically designed body enhance comfort when worn. What surprised me the most was the sound quality of this headset, with the blessing of 11mm drivers, special materials, dedicated DAC chips and aptX technology, the iron triangle CKR7TW truly achieved an audio experience comparable to Hi-Fi. The flexible operation mode and the non-bad battery life have significantly enhanced the practicality of the iron triangle KKR7TW in daily life. The performance of the Iron Triangle CKR7TW should not disappoint you as a Hi-Fi enthusiast.
