"There are scars and stories, which have been silent but far away. There are expectations and confusion, but we have not met each other but met because of Laisheng". This is not a love poem, but Laisheng Technology's interpretation of its brand, and it is also the perception of the founder and his team's early efforts to start a business and now realize their dreams. When Xiao Bian got the new product of Laisheng Technology RX-1, he not only felt its grassroots flavor, but also wanted to describe it with a 2016 annual catchphrase, that is, the product built with "craftsman spirit".

1. Packaging and unpacking

Maybe I have seen too much about the mainstream paper packaging and conventional packaging, and Laisheng RX-1 has given me a great surprise on the product packaging.

The outer package of Laisheng RX-1 is made of high-strength (PMMA) injection molding material, which is extremely transparent, extremely hard, odorless, reusable, and high-end. The whole package is made of plastic film, which can effectively prevent dust from entering.

The silicone bracelet customized by Raytheon is used for packaging sealing, which can be used as both sports equipment and strapping tape, more fashionable and cool than sticker sealing.

A base made of pure natural wood is included in the package. The base can be used to fix earplugs and also serve as the base of mobile phones. It can kill two birds with one stone, which shows that the manufacturer is very careful.

The accessories of Laisheng RX-1 are very rich. In addition to the wooden base and earphone body, it also includes a storage bag, two pieces of silicon tape, collar clip, Laisheng's metal logo, six pairs of imported sponge covers and manual after-sales card.

2. Appearance and accessories

In terms of appearance design, RX-1 adopts an all metal cavity, which looks very good in overall appearance. The designers of Laisheng refer to the front lights of sports cars, which makes the appearance of RX-1 unique.

The RX-1 chamber is made of zinc alloy by hot melting casting, and then goes through more than ten processes such as manual polishing, polishing, electrode removal, oxidation, electroplating, oil spraying, etc. The metal cavity has high anti-wear and oxidation resistance. Let consumers experience the metal texture of super industry more intuitively.

Compared with today's mainstream earphones, the flat head design of the Laisheng RX-1 is a bit out of place. However, the low frequency of the flat head plug will be more concentrated with the Shanghai cotton sleeve, and the low frequency sound quality will be improved. Its front end is a metal filter screen, which not only ensures durability, but also is very easy to clean.

The design of the wire body is very unique. It uses oxygen free copper enameled wire with built-in TPE-3D wire, which is soft on the whole. It is slightly thicker than other brands of earphones, and it is very easy to manage the wire.

The headphone wire splitter is small and beautiful, and the shape and color match well with the wire body.

The RX-1 adopts all metal plug sleeve, which basically eliminates all possibilities in terms of damage resistance. The internal mold is integrated with injection molding, and the spiral detachable design is full of details.

The product is equipped with ordinary sponge sleeve and hollow sponge sleeve, which plays a great role in improving the wearing comfort and sound quality of the entire earplug. The hollow sponge can prevent the common sponge sleeve from deepening the low frequency while weakening the weakness of the medium and high frequency. It can not only enhance the effect of low frequency in the sense of hearing, but also reduce the loss of high tone.

The headset is also equipped with a collar clip, which can easily fix the headset cable on the clothes.

The storage box of the Laisheng RX-1 is also unique. It looks like a trunk, and the material looks very solid.

3. Sound effect experience

After appreciating the appearance and workmanship of the Laisheng RX-1, we can feel the expression of "craftsmanship" in this product. Of course, no matter how beautiful the appearance is, it is the absolute principle to make a good sound. Sound performance becomes the next answer to be revealed.

The input impedance of Laisheng RX-1 is 15 ohms, and the sensitivity is 105dB@1KHz In terms of parameters, the lower impedance is very easy to be driven by the front end. The mobile phones we use everyday are enough to drive this headset. The higher sensitivity can reflect the quality of various front ends very well. Xiao compiled an Android platform and a mobile phone with very good HIFI capability as a test machine, found some lossless music in ape format, and appreciated the sound effect of Laisheng RX-1.

I selected Daolang's "Lover", "Impulsive Punishment" and other tracks for high-frequency sound effects testing. Under the new situation of not burning the machine, the high frequency performance of Laisheng RX-1 is very amazing. First of all, there is basically no sense of high frequency distortion and burr. The feeling that high frequency will not break through runs through the whole song. The excellent performance of high frequency proves that RX-1 has been very successful in transparency and high frequency control.

I selected Liang Jingru's Courage, Happy Break up and other tracks for mid-range sound effects. Liang Jingru's voice is full of emotion, and her breath and trill are clearly expressed, so she can feel a touch of sadness. The mid-range voice is stretch, natural, and the soft female voice is very appealing and flexible without narrowing the range.

I selected I Want My Tears Back to test the low-frequency sound effect. The low frequency resolution of Laisheng RX-1 is really good. The overall sound effect is solid, concise, responsive, and flexible. The low frequency of such a fast rhythm is still very clear and orderly. The transient performance is really excellent, and it sounds clear and dry.

In order to further appreciate the analytical power of earphones and their ability to restore musical instruments, I conducted a string music audition. One of the auditions was the violin concerto Butterfly Lovers. RX-1 earphone has excellent sound field depth, high frequency extension and detail performance, especially strong ability to reproduce overtones of instruments. A large number of different types of music were used in the evaluation of the minor editor. In general, RX-1 has a comfortable sound field, good analytical power, balanced three frequencies, smooth connection, and no stiffness.

In terms of wearing comfort, if I use a word to describe RX-1, what I can think of is "comfort". The customized shape of the headset is round and smooth, which can fit the ear. Listening to music with this headset will not feel tired, and everything is just right.

4. Summary

Through a few days of careful tasting of this Laisheng RX-1 headset, I have been surprised by many things. Regardless of the appearance design and sound effect, I can feel the enthusiasm of Laisheng Technology for this product, which also reflects the "craftsmanship spirit" everywhere. I have to say that it will set a good example for domestic headset manufacturers. We look forward to Laisheng Technology continuing to launch better and more affordable works.
