preface

I am a hardcore direct promotion party. In my concept, the earphone can only be placed on the table, so that for so many years, except for a Bluetooth earphone bought when I graduated from college, there has never been a portable earphone in my portable device.

When I received the Raytheon GR-1 this time, I did not regard this product as a device I would use in the future, but just signed for and unpacked it routinely. I couldn't help marveling at the workmanship of this small earbud until I completely unpacked the package and held GR-1 in my hand! Because its workmanship is so good, the all metal body has been polished very carefully, and no sense of cheapness and defects can be found from any angle. I immediately turned black and pink, and began to play with this small and beautiful thing carefully.

Design

Let's talk about design first. The biggest highlight of GR-1 should be its unique design aesthetics. The diamond cutting shape on the front reminds me of HTC's shocking Diamond mobile phone many years ago. This design should be the first time to be used in portable ear amplifiers. Even though I have played with numerous digital products, I am still impressed by such outstanding design language. The body of GR-1 feels very smooth. Due to the use of all metal materials, the weight of the whole machine has increased, but it is also because the weight of GR-1 is slightly larger than that of products of the same level that has brought great improvement in texture. The GR-1 without wires is just a small handicraft in your hand.

Due to its positioning as a portable device, GR-1 does not use the same digital connection port (line out) as professional earphones. Instead, it uses the design of direct connection with the handset or player headphone output port. Although the sound quality will be discounted in theory, it will largely save the power of the device. I believe this is also the design idea of portable devices.

Auditory sense

This time, I used my most commonly used listening device - iPhone7Plus. Because I usually listen to pop music from Japan, South Korea or China, even though I have been tossing around Sony, Alihe Cowon， But in the end, I still feel that Apple's tuning is the most endurable and I like it most. However, it is embarrassing that the 3.5mm headphone output port of the iPhone7Plus has been canceled. When connecting the Leisheng GR-1, a headphone adapter must be used to assist the connection. Although the sound quality is not lost, the design will be distorted. The earphones connected to the earphone are the Sony xba-h3 iron earphones and the headworn 1ABT. The former is a very thrust free type, and even the direct push of iPhone can achieve a good use effect. The latter is the main Bluetooth connection, which requires high thrust after using audio cable connection. At least the direct push effect of iPhone and Sony A series player is difficult to accept.

Next, I will use specific audition tracks to interpret the subjective listening sense of Leisheng GR-1 when playing different music.

1、 Previous Lives - The theme song of Radswimps, which comes from the popular animated movie Your Name a few days ago, has also gained high popularity in China. The best proof is that it has been almost heard all the time recently when shopping in the mall. Since the first paragraph is an iPhone, a sense of atmosphere is a basic guarantee. After connecting to GR-1, the coil iron headset H3 has significantly improved its medium and high frequencies, and its low frequencies are also more textured. The first half of the whole song has been greatly improved in all aspects. But after all, it is an entry-level device. When GR-1 performs the chorus of "Previous Lives", it is inevitable that there will be some confusion, which gives a certain discount to the listening sense of the whole song. The performance of 1ABT connected to the audio cable is relatively stable after using GR-1 to connect to the iPhone. The improvement in the sound field has basically reached the level of LDAC connection, which is much more obvious than that of direct push. Although the mid-range of 1ABT is slightly depressed, with the help of GR-1, the performance of vocals has also improved significantly, especially in the song "Previous Lives", the texture of the male lead singer's voice has been restored in place, so that people can begin to enjoy the song.

2. "Decalcomanie" - MAMAMOO MAMAMOO is a pop women's troupe famous for singing skills that has sprung up in South Korea in the past two years. The singing level of several members is very good. This song "Decalcomanie" is the latest work that won the first place in weekend music programs several times a while ago. When GR-1 is connected to Sony H3, the main improvement of songs is still in the sound field and the high-frequency extension of vocals. The performance of female and male timbres is very different, so that after the sound field of Decalcomaniae is also optimized with that of the former, the former will not appear mixed in the chorus as the latter does. On the contrary, The chorus of Decalcomanie became very beautiful and amazing, which may be the biggest advantage of H3 after GR-1 brought about the thrust increase. On the other hand, although the sound of 1ABT connected with GR-1 has also broadened a lot, and the sense of location and low frequency of percussion music are commendable, there are some grainy and mixed feelings in the key vocal. But later I saw that various players' feedback on the Internet also showed that 1ABT was a lower earphone, which had insufficient control over the voice. No wonder GR-1 could not serve it well.

3. Call Me Baby - EXO EXO I don't believe I need to introduce it. This group, which is well-known in South Korea, China and even the world, is one of the most popular groups among girls. "Call Me Baby" is a classic dance song that they won the award last year. The song has a lively and compact rhythm and is very popular. Sony H3 has been able to show the poisoned current sense of the song under the direct push of the iPhone. With the help of GR-1, the already good low-frequency is more textured and flexible, and the percussion position in the song is clearer. Both the horizontal and vertical sound fields have reached a higher level. The improvement of 1ABT is more obvious after connecting with GR-1. The low-frequency strength has been increased a lot, but the quality has not lost a bit. There is a kind of pleasure from fist to meat. As EXO is a male group, the voice of the members of EXO in 1ABT has also grown a lot after the huge increase of the thrust, which is the key to improve the quality of the songs. The interpretation of CallMe Baby has been pushed to the extreme under the rolling of the electric flu that is easy to understand and linked layer by layer.

summary

The ear amplifier GR-1 of Laisheng has not abandoned any pursuit of sound quality while making its design dazzling. Although we know that portable ear amplifiers are difficult to show a sense of hearing comparable to desktop computers, for most users, GR-1 can still bring great improvement to the sound quality of portable devices and make people enjoy it. Finally, there is a small regret on GR-1, that is, it takes a long time to charge. I hope manufacturers can add the fast charging function when designing the next generation of products to make the products more practical. However, shortcomings do not hide the merits. Among the entry-level portable ear amplifiers, GR-1 is still an excellent product with full competitiveness.
