5. Included Accessories: The package includes 22 pairs of eartips for a customized fit, a cleaning brush, and a carrying case.
The brand-new FiiO FX17 are high-end earbuds that feature a lightweight titanium shell. Each earbud is equipped with 13 drivers, including a 10mm dynamic lithium-magnesium driver. Moreover, there are four Knowles Balanced Armature drivers specifically designed for the FX17, along with eight electrostatic drivers from Sonion.
Complex Driver Setup
To achieve optimal sound, FiiO has implemented five crossovers in this configuration. The diverse mix of driver types is expected to enhance audio quality. The electrostatic tweeters can theoretically cover frequencies above 50kHz and have a sensitivity of just 99 dB/mW, which means they may be less loud than dynamic drivers. However, with eight of these drivers in the in-ear design, their volume should be higher overall. The mids are handled by the Knowles Balanced Armature drivers, while the dynamic driver takes care of the bass.
Sensitivity and Cable Features
The FiiO FX17 boasts a sensitivity rating of 104 dB/mW and has an impedance of 16 ohms. These new earbuds come with a replaceable MMCX cable, making it easy to swap out if necessary. The included 4ft cable is a combination of gold, silver, and copper materials and can be fitted with either a 3.5mm, 4.4mm, or USB-C plug. The USB-C adapter includes a built-in DAC that supports audio quality up to 32 bit at 384kHz.
Pricing and Accessories
Currently, the FiiO FX17 flagship earbuds can be found on Aliexpress for $1,515. To provide the best fit, these headphones come with 22 different pairs of eartips. The plug of the supplied cable can be changed, as FiiO provides options for 3.5mm, 4.4mm, and USB-C connectors. Additionally, a cleaning brush and a carrying case are included in the package as well.

5. The app offers a free plan for five songs monthly and a paid plan for unlimited songs and additional tracks, with the paid plan currently free until August.
Yamaha Japan has introduced an innovative app called Extrack, tailored for musicians who want to learn and perform songs as if they were jamming with a band. The app is currently available for download on Apple iOS, while Android users can expect it to launch in April.
Features of Extrack
Extrack starts by analyzing the song files that users download, identifying the various vocals and instruments within the track. It then separates these components into individual tracks. Musicians have the flexibility to adjust the volume of each track or even mute them completely, enabling them to practice alongside a particular instrument or concentrate on mastering one specific track.
Learning Made Easy
To enhance the learning experience, the app automatically shows chord progressions for piano and guitar tracks, making it easier for users to follow along. Moreover, the playback speed can be modified, and certain sections of a track can be set to repeat automatically until the user feels they have mastered that part.
One standout feature for vocalists is the key change option, which modifies the track to fit the singer’s natural vocal range. During playback, all instrument tracks can be muted, allowing users to focus solely on learning the lyrics.
Pricing Plans
The app offers a free plan that lets musicians split up to five songs each month into four tracks (bass, drums, vocals, and others). For those looking for more features, a paid plan is available, which allows for an unlimited number of songs and seven tracks (bass, brass, drums, guitar, piano, vocals, and others). Currently, the paid plan is being offered for free until August.

Affordable DIY Eavesdropping Device for Lightning-Fast Listening
Key Takeaways
1. Basic Components: A functioning laser microphone can be made using three main parts: a laser, a photodiode, and an amplifier circuit. An optional fourth component can enhance its capability.
2. Working Principle: The laser microphone captures sound by directing a laser beam onto a glass surface. Vibrations from sounds modulate the laser reflection, which the photodiode detects and converts back into audio.
3. Easy Sourcing: Photodiodes can be easily sourced from devices like televisions or smoke detectors, while the amplifier circuit can be modified from existing electronics.
4. Setup and Configuration: Proper setup involves replacing a built-in mic with a photodiode, modifying a USB cable for power, and positioning the laser beam correctly to ensure effective audio capture.
5. Performance Limitations: The system can be affected by environmental vibrations and obstacles. Improvements, such as using a 3D-printed case and adding a filter, can enhance performance.
With so many electrical parts available today, it’s no wonder that anyone can create a functioning laser microphone from common items. You can find the necessary components at online stores, or even scavenge from e-waste lying around your home. By using three main parts, and optionally a fourth, anyone can eavesdrop on sounds from afar with a homemade laser mic. The process is quite simple, provided the user has a device capable of recording mono audio.
How Laser Microphones Work
According to SomethingAboutScience, the way a laser microphone operates is by directing a laser beam onto a window or picture frame inside a room. The beam’s reflection is captured by a photodiode. Any sounds produced within the room create vibrations in the glass, which in turn modulates the laser reflection. The photodiode is then able to detect these changes and convert them back into audio. Interestingly, SomethingAboutScience mentions that you don’t necessarily need a red laser; an infrared laser can be a stealthy alternative.
Sourcing Components
Finding a photodiode is quite easy since it’s commonly found as an infrared receiver in televisions and certain smoke detectors. However, the diode cannot work by itself because the signal from the laser is too weak. This is where an amplifier circuit becomes useful; it amplifies the signal, provides necessary power, and transmits mono sound. In this instance, a modified amplifier circuit similar to the MAX9814 was utilized. To create the laser microphone, the built-in mic is taken out and swapped for the photodiode. A USB cable is then modified and soldered to the circuit board for power, and a mono audio wire with a jack is attached for audio output. Once everything is set up, it’s just a matter of positioning the laser so the beam strikes the photodiode at a perfect angle to capture the sound modulations effectively.
Limitations of the Setup
Though this assembly is straightforward, it comes with some drawbacks in terms of performance. For one, both the laser and the photodiode can be affected by vibrations in the environment, and any objects between them can interrupt the audio transmission. To help improve this somewhat, SomethingAboutScience created a 3D-printed case and added a filter to the receiver, leading to slightly better results. In summary, this project is open to further improvements and highlights how a bit of DIY creativity can yield great results. Those curious can explore more about the construction and outcomes via the links provided below.
