The headphone terminal of the new MacBook Pro seems to be confident in the output, so I tried to see if the 600Ω headphones sound

Apple has released the latest MacBook Pro. This model equipped with the enhanced version of the original SOC "M1" "M1 PRO" and "M1 MAX" has enhanced audio output from the 3.5mm headphone jack, and the headphones with high impedance have been sounded alone. I verified it with a 16 -inch MacBook Pro equipped with a top M1 MAX chip. [Photo] Check with the popular headphones. First, the exterior of the new 16 -inch MacBook Pro, but a 3.5mm headphone jack is provided on the left side of the main unit. The USB-C compatible Thunderbolt 4 terminals are two on the left and one on the right. On the right is the HDMI terminal and SDXC -compatible slot after a long absence. On the right is a Magsafe 3 port that allows the terminal to be smoothly attached and detached with a magnet. I am a Mac user waiting for the Magsafe port to return to MacBook. If it is fixed with a USB-C terminal, it will be dedicated when hooking your feet on the cable. I hope the happiness with the Magsafe port on the MacBook will last a long time. And I would like to hope for a comeback for the new MacBook Air in the future. The 16-inch MacBook Pro has a large 140W USB-C power adapter. The reason for the large output adapter is that the MacBook Pro is a machine that requires a lot of battery when driving, and to achieve high -speed charging of the new features that Magsafe ports support. With a high -speed charging function, you can charge a 50 % battery in about 30 minutes. If you want to carry it when you go out, you can use a more compact adapter, and you can supply and charge the TUNDERBOLT 4 terminal. Now, let's approach the ability of the new MacBook Pro headphone output, which is the subject of this report. If you refuse earlier, Apple has not disclosed specifications related to Mac headphones. This time, special events and product information also mention the new MacBook Pro that "high impedance headphones are highly supported." I would like to report again when the planning intentions and additional information are found, but this time I would like to report my hearing impressions. The first headphone I tried was Zenheiser "HD 820". The impedance is 300Ω. For the audition, I chose Apple Music's lossless sound source and listened. Indeed, it sounds well. You can enjoy a powerful music playback sufficiently at the position of the volume gauge around "5". When the same song was played on the MacBook Air equipped with M1 chip in 2020, the same volume was reached when the volume gauge was raised to "10". Next, I listened to the Bayer Dynamic "T1 2nd" with a 600Ω impedance. In the MacBook M1, the volume obtained by raising the scale of "12" and "13" can be heard at the MacBook Pro, which does not reach 50 % of the gauge at the "6" and "7" scale at the scale of "6" and "7". Regarding the sound quality, it is not as good as the quality when it sounds with an external headphone amplifier, but it is still possible to bring out the information contained in the music source. It seems that it can be used enough to check the details with a high -impedable monitor headphone, which seems to be the main purpose of this headphone terminal. The new MacBook Pro also supports spatial audio regeneration using the built -in speaker of the main unit. It seems that you can enjoy the spatial audio content by Dolby Atmos, which is distributed by Apple Music, as a speaker with a built -in battery that can be carried and enjoyable.
