From sporting ears to super -dreadnought players.Listen to Sony "overkill" audio

IFA's Sony audio products can be roughly classified into three.

First of all, two new products were introduced in a group of general products with enhanced functionality.

The latest version of the noise Canceling Headphone MDR-1000X series "MDR-1000XM3 (380 euro)" has a new chip with the latest DSP, which has a long battery drive and higher noise canceling performance.

The other is WF-SP900 (270 euros), a left-right wireless earphone that can be used in swimming by using a crossfit that moves the body in various postures, or using a waterproof chip and a built-in memory.

Next, the high -quality headphones for the general public.

The "IER-M9" and "IER-M7", which are not sold in Europe, are in-ear headphones that are a multi-way 5 driver for the former and a 4-way 4 driver in the latter and a 4-way 4 driver.Developed for music production and artists, it boasts extremely high sound insulation as a universal fit.All driver units are Sony's unique design and production, and the playback band is tuned according to this product.

The MDR-Z7, which triggered Sony headphones globally, under the full model change and the MDR-Z7M2 (800 euro) was exhibited.The sound quality tendency has been sent close to the MDR-Z1R, and the total quality, such as reviewing the attached cable, is increasing.However, as far as the European price is seen, it seems that the price is slightly higher than the conventional machine.

Finally, engineers are "IR-Z1R (European Price 2,200 euros)" and digital music players "DMP-Z1 (European Price 8,500 Euro)" in the signature series that aims to high quality in "specific genres".It has been added.Both have been unveiled at the Hong Kong audio show in August, but this is the first time for a large exhibition.

The more you delve into each of them, the more interesting the story will come out, but here I would like to tell you the first impression with a quick rush.

By the way, each product has its own characteristics, but I would like to mention the WF-SP900 that includes the left and right independent wireless earphones and also includes a waterproof chip.It may be considered as "supplement" for the earphone review for runners who have reviewed earlier.

At that time, I tried the NW-WS413 that could be used in swimming, but I didn't get a very good impression.The reason for the installation of the waterproof tip for swimming will reduce the volume and lack absolute sound pressure, but I felt a little uneasy about the installation stability, such as kicking the wall in the turn.It is.

Some products are attached to the swimming goggles when they look at other companies, but among the single -function Bluetooth earphones, this unit is extremely compact and lightweight.One side 7.3 grams and 0 from the WF-SP700N announced at CES in January.It is lightweight, although it is 3G, and looks slim.

Unfortunately, Impressions during swimming cannot be delivered, but according to the planning and development staff, a careful arc supporter (stabilizer stabilizer that stabilizes along the earlobe groove) and body shape so that it does not fall off when a wall is kicked during turns.It is said that the adjustment was made.The size of the ear arc has also been increased from the previous two to three.

In addition, in order to optimize the positional relationship between the arc supporters and the ear chip, the installation depth of the ear chip can be adjusted in two steps.Good news for those whose arc supporters are easily off the groove during running.

I actually put it on, but in the case of the writer, the arc supporter with the right ear was easy to come off, but it was stable to change the depth of chips on the left and right.It is lightweight and compact and stable regardless of the head direction.

I would like to avoid speeches because I have not tried the use of swimming during swimming, but I do not have to worry about loss even if it falls off because it is attached to a leash cord that prevents loss of falling off in connection with goggles.Especially if you run.

It is said that it is adjusted so that it is hard to come off during cross -fit training or stretching, so it is important to pay attention to the stable wearing feeling that does not depend on the posture.Among the left and right independent wireless earphones for sports that have been tried so far, it is a sense of stability and security of the tsuts.

In addition, 4GB memory is built -in so that it can be used even when swimming with radio waves, and music playback with earphones alone is realized (operation can be performed by tapping acceleration sensor), and left and right earphones are bonded SP700N.It has been changed to a combination of magnetic resonance communication.To make it possible to use underwater, but 2, such as station in the city center.Isn't it difficult to cause problems such as left and right sound out of sound even if the 4GHz band is crowded?It is expected to be.

On the other hand, "noise canceling" is not installed as you can see from the absence of N at the end.However, there is a microphone that collects external sounds, and the function of mixing the surrounding sounds at the appropriate volume when running in the city is installed.

This is said to have removed the noise canceling function with the aim of specializing in sports use with the aim of balancing "smaller weight as possible" and "waterproofness that can be used for swimming".On the other hand, considering the built -in music playback function, it may be a wise choice.

The battery case has a capacity that can charge the main unit three times.The continuous use time when used as a Bluetooth earphone is 3 hours and the same as SP700N, but the total regeneration time is 12 hours.However, if you use the built -in music playback function, you can play 6 hours alone.It is a playback time that can be fully affordable for those who are challenging the citizen marathon.

Finally, the sound quality is a single BA driver configuration for smaller weight.BA often uses multiple pieces because the regenerative band is narrow.For example, BA-adopted earphones of Etimotic research ER-4 have low low-frequency reproduction abilities in exchange for the delicate expressive power of the high frequency range.

In the case of this unit, it seems that custom BA drivers are produced in -house to the slightly lower bandwidth, rather than the early BA adopted earphones.Instead of the high -range stretching and high resolution, they are listened in a well -balanced manner, mainly in the midrange.If you think of it as a product that enjoys music while moving your body as a “sports”, it can be said that it is a decent sound.

Excluding noise canceling functions and music playback functions, it has a function that is equivalent to the SP700N, and can also adjust the equalizer and sound quality from the application.
