OTR is the abbreviation of On The Road. On the Road describes young people's pursuit of unruly and free life in the 1960s. It is a worthy hippie bible. The little prince's poisonous face is believed to be an excellent collection, since it can't go back to the used ones.

The paper bag given as a gift is also very personalized, and I believe it is a good choice to give it away.

This OTR version is equipped with retro suitcase boxes to pay tribute to Jack Kerouac. "Our tattered suitcases are once again stacked on the sidewalk; we still have a long way to go", which adds to the force of the little prince.

The back of the box is engraved with the name, model, voltage, manufacturer, etc.

The beautiful belt and convenient gold buckle can feel the perfection of Elvis design and pursuit of perfection.

The Little Prince OTR has four color combinations, pure white to pay tribute to the Woodstock Music Festival in 1969, and 450000 hippies to build a utopia in the pure age, love and peace; The retro green salutes Lulinweizhi Village in New York in 1965, where the golden age of hippies was unveiled; Western Huang paid tribute to Jack Kerouac's "backpack revolution"; Hippie red salutes the carnival, drinking and singing in San Francisco in 1967.

I received the retro green, which is a touch more fresh than the retro green of the Little Prince's solid wood before.

The attached cards and stickers are also personalized.

What is different from the past is that the charging line and AUX line are separated. It is also recommended not to charge while listening.

The manual is also retro, and it also contains two postcards. The girlfriend who loves collecting is happy for a long time.

The biggest difference of the OTR version is that the material uses a new high-density zinc aluminum alloy. Inspired by the 60s car baking+electroplating, it looks very shiny and smooth, but the weight has increased to 430g, which is much heavier.

The top, bottom, left and right front five sides are diecasted together. The edges connected with this are very smooth. The top is also a curved surface rather than a plane.

Because the metal is smooth, two anti slip rubbers are designed at the bottom.

There are three knobs and indicator lights on the front. The knob on the top is responsible for adjusting the channel, and the two buttons on the bottom are responsible for adjusting the volume and mode. The accuracy of the knob is much higher than that of the little prince, and it is easier to rotate.

The different colors of the indicator lights in different modes and the luminous dials give the little prince OTR vitality, which looks very smart and charming.

There is a USB/AUX interface and flip antenna on the back. There is a charging indicator beside the interface, which displays red when charging, and green when fully charged.

The whole machine is small and exquisite, so it is called "Little Prince". It can be easily held in the palm of your hand with one hand, which is very convenient to carry. The feel of metal spray paint is silky and smooth.

Although it is a stereo, it can also be used as decoration. This fresh green can definitely add artistic flavor to the room.

In terms of sound quality, I can only talk about my personal feelings. Because I am totally amateur, the overall sound quality is relatively comfortable. The OTR version is improved compared with the ordinary version, but the sound field is not wide enough. I feel a bit stuffy and hoarse. The bottom noise is relatively high, but it can be heard only when the volume is adjusted to zero.

The opening scene of Hotel California is immersive. It can clearly distinguish different musical instruments, but it still feels that the sound field is not wide enough

Here's to Never Growing Up has clear accompaniment and pure treble

Haven't seen you for a long time. I don't think you can dive enough

The effect of the bass plate of Butterfly is quite shocking. It's very impressive

The Year in a hurry The voice is clear and penetrating

Between Mountains and Rivers (ethereal version) The opening musical instrument feels very three-dimensional, and the voice is very transparent. Does the little prince prefer female voices?

When it is used as a radio, if it is tuned to the appropriate channel, the sound is very clear and there is almost no noise.

In terms of battery life, it's also very good. At normal volume, Bluetooth can listen for 10 hours, and the radio can listen for 20 hours.

In general, the little prince OTR has added a fresh feeling on the premise of the past retro style. It is small and exquisite. The suitcase storage box equipped with it is more convenient to carry. The sound quality is suitable for entry-level. If you value appearance, it is really suitable for collection. If you want to say the disadvantage, I think that there is no power display, which makes me feel insecure.
