The packaging design of Shikai OpenRockPro is interesting and full of Cyberpunk. I thought the color matching of the earphone body would be quite beautiful, but I didn't expect to take a calm and textured route, which is quite business-like.
A family photo, charging box, headphones and USB-C data cable. Because it is an inaudible design, there is no earmuffs attached to the accessories. Paper materials are quite rich. In addition to the instruction manual and warranty card, I also presented various styles of stickers, as well as the display card of the correct wearing method, which was very intimate.
The cobblestone shape of the charging box, pure black color matching, frosting technology, the overall texture is very rich, feel good. The surface is designed with some U-shaped groove twill, which can play the role of anti-slip, and to some extent, it also increases the sense of monomer of the charging box, making the black look less monotonous.
The charging box is a two-stage design, the upper and lower parts are connected by hinges, and the connector is fixed by magnetic attraction, so don't worry about opening it by mistake. When the top cover is turned up, the space in the box can be exposed, and the left and right earphones are erected and inserted into the lower half of the box.
The left and right earphones are signed, so you don't have to worry about plugging them backwards when you put them in the charging box. Moreover, there is a strong magnetic attraction at the ear handle, so the charging box will not fall off when it is turned over. There are pairing buttons, USB-C charging interface and power indicator light at the bottom. Click the pairing button to display the current power, press and hold the lid open for 3 seconds to enter the pairing state, and press and hold the lid open 10 second to clear the pairing information.
Because of the ear hook design, the earphone is bigger and heavier than the ordinary TWS earphone, with a unilateral weight of 13g. The ear hook is an adjustable skin-friendly silicone hose that can be adjusted according to the user's auricle to match different ear shapes. The inner side of the earphone is a sound hole, and the 16.2mm dynamic speaker is relatively large in TWS earphone.
The black and silver color matching and frosting treatment of the OpenRockPro earphone body are very textured. A small piece of silicone material is added between the cavity and the ear hook, which can be fine-tuned according to different ear shapes of each person, thus achieving a more comfortable feeling.
There is a multifunction button at the bottom of the left and right earphones. By clicking, double clicking, triple clicking, long pressing, etc. , which can realize rich interactive functions such as playing, pausing, answering, hanging up, increasing or decreasing the volume, and waking up the voice assistant. Now, in order to prevent accidental touch, the click is basically cancelled on the Bluetooth headset with touch, but you don't have to worry about the physical keys.
Shikai OpenRockPro supports four-microphone call noise reduction, and the left and right headphones are integrated with two high-quality microphones respectively. With the blessing of Qualcomm CVC8.0, the array is formed by beamforming technology, which can effectively eliminate the ambient sound. It is measured that in the noisy environment of bus or subway on commuting road, both parties can hear very clear voice.
Shikai OpenRockPro supports aptX/AAC/SBC audio decoding and frequency response range of 20Hz-20Khz, which is beneficial to the physical structure of large cavity. Equipped with 16.2mm super-large moving coil unit, it has good performance at both high and low frequencies, especially at low frequencies. Thanks to the exclusive patented technology of TubeBass low-frequency enhancement, it has deep dive, rich sense of quantity and excellent connection.
In-ear headphones have a certain noise reduction effect, so they have a strong sense of immersion. The disadvantage is that they are very comfortable for a long time, while the bone conduction is much more comfortable. However, due to the acoustic structure, they are inherently inadequate in restoring timbre details. Earphone seems to combine the advantages of both, and find a balance between sound quality and comfort. The actual feeling of OpenRockPro is like putting a pair of small speakers in headphones, which can get the best sound quality without affecting the interaction with the ambient sound.
Shikai OpenRockPro has IPX5 waterproof rating, which is no problem in dealing with general rainy weather and sweat. The open structure has the advantages and characteristics of bone conduction, and the sound quality level is almost the same as that of in-ear headphones with the same gear. After a period of use, I personally think it is a very good choice to use it in sports. Of course, for swimming, it is still bone conduction.
Before I started, I saw in the official data that the single battery life of Shikai OpenRockPro was 19 hours. I was really shocked at that time. I repeatedly confirmed with the customer service that it was not the artist who added a 1 by mistake before 9. When I got it, I was relieved to see the structure of the earphone. Although detailed battery information was not found, the battery capacity of 40mAh ordinary in-ear Bluetooth headset can reach 6 hours of battery life. It is more than enough to open a cavity as big as OpenRockPro and insert a battery of 150mAh, so the single use time of 19 hours, plus the total battery life of 46 hours, is not so scary.
In addition, OpenRockPro supports fast charging. Under normal circumstances, it only takes about 1.5 hours to charge the battery from 0 to 100%. When the power is exhausted, you can get 1 hour of power after charging for 5 minutes, which can solve the urgent need.
To sum up, Shikai OpenRockPro is an open earphone, which is more comfortable and refreshing without entering the ear canal. It has four microphones to reduce noise and can accurately pick up human voices.
