The Logitech S150 Vs. the S120by Tyson Cliffton
The Logitech S-120 and S-150 speakers are designed for portability, so you can quickly connect your laptop, PC or other supported device and output quality sound. However, depending on the type of connectivity you're looking for, the power source you have on hand and even the quality of the audio you want, there are some differences between the devices that could make one a better fit for you.
The Logitech S-120 speakers output 1.15 W per speaker between the two speakers. Alternatively, the Logitech S-150 speakers output 0.6 W per speaker between the two speakers. The total wattage doesn't have any impact on the quality of audio being outputted, but higher wattage means the speakers can achieve higher volumes.
The Logitech S-120 features a frequency response range of 50 Hz to 20 KHz. Alternatively, the Logitech S-120 features a frequency response range of 90 Hz to 20 KHz. A speaker's frequency response indicates the sound range the speakers can successfully replicate before the quality of the audio reproduction starts to suffer. This can be important to take into consideration if you appreciate deep bass or high treble.
The Logitech S-120 speakers are powered through a 1.5-meter AC cable. Another 1.2-meter cable carries power between the two speakers. Alternatively, the Logitech S-150 speakers are powered through a 1.2-meter USB cable that can be connected to a computer or any high-power USB port. Another 1.2-meter cable that carries power between these two speakers as well.
The Logitech S-120 speakers offer a 3.5-mm headphone jack where you can connect a laptop, MP3 player, tablet or other device to the speakers and output that device's audio through those speakers using a 3.5-mm cable. Alternatively, the Logitech S-150 speakers don't have a headphone jack, and instead connect to other devices via the USB connector.
