Since iPhone 5, all new iPhones and iPads have been equipped with Lightning data interfaces. In particular, the 3.5mm audio interface has been directly canceled after iPhone 7. Considering factors such as the thickness of the phone, the built-in audio part has been removed, the 3.5mm audio interface has been canceled, and only one Lightning interface has been retained. This is a major feature of future iPhone development and also brings development opportunities for the headset with Lightning interface, 1MORE is a new audio equipment manufacturer in China. Recently, it also launched a Lightning headset exclusive to Apple - 1MORE HD noise reduction ring iron headset (Lightning Digital version), the mobile phone is only responsible for transmitting digital signals to the headset. Compared with the 3.5mm interface of traditional analog technology, the signal can be transmitted without loss. The headset also integrates the codec responsible for analog output, no longer relying on the codec of the mobile phone. The sound quality is determined by the headset. In addition, the 1MORE HD noise reduction coil iron headset (Lightning Digital version) also adopts active noise reduction technology.

The design of the packing box is dominated by the dark background, and the back has detailed introduction to the characteristics and parameters of the headset. The small "red label" in the upper left corner of the front is the award-winning logo of the German iF Red Dot Design Award, and the logo of Made for iPod, iPhone and iPad is in the lower left corner. It is exclusive to Apple products and has been officially certified by Apple MFi, which also means that the headset has been recognized by Apple and other institutions in terms of technology and quality, and its strength is obvious to all.

The inner packaging follows the common design of 1MORE high-end products. On the left is the design sketch of the important parts of the headset. The overall packaging is exquisite and the accessories are rich, giving a feeling of height, size and elegance.

The earphone shell is made of aluminum alloy made by aero titanium technology, and integrated with multiple processes, such as fine sand blasting, high gloss drilling, wire drawing, patent CD pattern carving, etc. The light and thin titanium metal has high hardness, which can provide solid protection for light and soft aluminum alloy. It is antiskid and scratch resistant, and is not easy to decolorize. Delicate and compact shape, strong metal texture, full of luster It's very eye-catching.

The earphone adopts an ergonomic 45 ° in ear design, with R and L in capital letters to distinguish left and right earplugs. It fits the ear firmly and comfortably when worn. The headphone unit is a self-developed low distortion moving iron unit. With the patented "moving iron direct drive" technology, the moving iron unit responsible for high frequency does not pass through the noise reduction unit, so there is no signal loss, and music can be analyzed and restored more completely and accurately.

In the online control part, a five dimensional navigation key is provided at the top of the front, which can play/pause, switch between up and down, increase or decrease the volume, answer the phone, and other functions. No extra keys are needed, and even blind touch is not easy to make mistakes. The earphone is designed with active noise reduction function, and there is a noise reduction switch on the side. The earphone can shield the noise by receiving and analyzing the external noise spectrum and generating a signal in the opposite phase to offset the noise. The noise reduction function does not require additional power supply or a built-in battery. The noise reduction module can be powered by connecting the iPhone. The wire control part integrates a high-definition digital decoding chip (its codec is 192k/24bit, and the SNR is 100dB+). The digital/analog conversion will no longer rely on the codec of the mobile phone, nor will it be interfered by the internal signal of the mobile phone. It can be said that the overall sound quality is completely dependent on the performance of the headset.

Lightning interface

The ordinary 3.5 mm analog interface will cause loss in the process of music transmission, while the Lightning interface is only responsible for power supply and data transmission, and cannot transmit analog signals. When digital audio is transmitted from mobile phones to 1MORE noise reduction headphones through the Lightning interface, the signal is zero loss, At the same time, it can also reduce the loss of sound quality caused by wires and sockets, as well as the noise caused by poor contact. Moreover, the earphone can be integrated with a better audio circuit than the mobile phone, so that the sound quality can be significantly improved.

Microphone of headset

The headphone cable adopts the "brocade pattern" braided cable, which is fashionable and tensile. The core wire of enameled copper wire is wrapped with Kevlar tensile fiber, which has strong toughness and can effectively extend the service life of wire rod.

Earphone accessories, including leather storage box * 1, silicone ear sleeve * 3, airbag outer ear sleeve * 4, cable clip * 1, Instruction manual * 1, product booklet * 1, and quite a lot of accessories. Various models of earmuffs can meet the needs of different users.

Audition

Listening device: iPhone 6s Plus

The main tracks for audition are mainly WAV and APE lossless formats.

First of all, audition was conducted in a quiet indoor environment. There was no noise around and the noise reduction mode was not turned on. Listen to Cai Qin's "Ferry" and the Eagle Band's "Hotel California". The low-frequency diving was quantitative, but also had a certain degree of strength. The dynamic and sound field performance was moderate. Listen to Huang Yingying's "Crying Sands" in terms of voice. The recording level of this song is relatively high, the voice resolution is good, and the pronunciation is clear, Feelings are full and drooling is obvious. Tenger's Paradise sounds strong, dense, and penetrating. When Jiang Zhimin's The Promise of the Past is played, the vocal and musical instruments are clearly layered, and the zither is bright, crisp, and deep in extension. The overall three frequency bands are relatively balanced, and can handle ordinary pop songs or vocals well. It sounds comfortable and endurable.

After the noise reduction mode is turned on, the music sound does not increase significantly, and there is basically no difference between the two. However, when an electric fan is turned on (the running and rotating of the fan will bring some noise), the noise reduction function of the headset will take effect instantly, and the noise generated when the fan is rotating will disappear, and you will only feel the breeze gently blowing on your ears and face.

Outdoor audition: when the noise reduction mode is turned on during walking, the volume does not increase deliberately, but suddenly becomes quiet around, and the buzzing sound of cars disappears, but there is still a certain sound from cars driving close to you when crossing the road. On buses, the noise reduction effect is particularly effective for the continuous hum and rumble of buses and buses, which is basically inaudible. The noise reduction effect is good, but it is impractical to completely isolate external sounds. Some sounds are clear and audible, such as the sound of bus stop announcements, and when the car decelerates or turns.

In terms of wearing, the earphone adopts an ergonomic 45 ° in ear design, which is relatively close to the ear, suitable for wearing, firm and comfortable. Due to the built-in codec of the remote control, the volume of the remote control is relatively large, and there is no cable clip for fixation when walking, there will be a certain load and slight shaking.

1MORE HD noise reduction ring iron earphone (Lightning digital version) has exquisite workmanship, rich accessories and built-in independent Codec codec, three frequency bands are relatively balanced, and the sound quality performance is commendable, The active noise reduction effect is obvious. You can enjoy music quietly when you go out or indoors, which is a good choice for Apple users.
