SoundPeats QY9 Design Picture

The QY9 have a sleeker design than the QY8 with slight improvements in the control scheme. The play/call button is in a better location than on the previous model, where it would force you to push the headphones deeper into the ear canal. They feel sufficiently dense and can handle a few drops without getting damaged. They're also stable headphones for sports. Unfortunately, the in-ear fit might not be comfortable for everyone.

Style
SoundPeats QY9 Design Picture 2

The QY9 are stylish-looking wireless in-ear headphones. They have a similar format to the QY8, but the earbud's design is a little sleeker and moves the play/call button to a better location than on the previous model. They have a simple matte black color scheme, and they're relatively large for in-ear headphones. However, they do not stick out of your ears like the SoundPeats Q8's design.

These headphones have a typical in-ear fit, which may not be comfortable for everyone. On the upside, the QY9 fixes the issue the QY8 had with the call/music button placement. The button no longer causes listeners to push the earbuds deeper into the ear canal, which was uncomfortable. They also come with a variety of tips to help you find a more comfortable fit.

6.5 Controls

SoundPeats QY9 Stability Picture

The QY9 are very stable headphones. They won't easily fall out of your ears while exercising at the gym. They're lightweight, and the in-ear design is inherently stable. They also have a wireless design, which means the likelihood that the audio cable gets tangled or hooked by something is low. That plus the additional tips provided to improve stability makes these headphones good for sports use.

Build quality is decent. The earbuds are lightweight and dense enough to handle a couple of drops without damage. The flat audio cable is thick and rubberized, which makes it less tangle prone and a bit more durable. Unfortunately, on some units, the audio cable has snapped relatively easily. This issue won't happen with all units but should be something you take into consideration before buying these headphones.

SoundPeats QY9 Frequency Response

The QY9 have a skewed and bass-heavy sound quality that's not for everyone. They won't be your first choice for critical listening headphones, the closed back in-ear design limits their soundstage and their audio reproduction is mediocre. The bass range is too emphasized resulting in a boomy sound quality, and they push instruments and vocals to the back of the mix. They also struggle to reproduce lead instruments with clarity and detail, resulting in an overall sound that's too dark and muddy for most listeners.

Average Bass Range performance. The L/R Bass Range response of our initial test unit was poorly matched. This is the response of our second test unit, which although much better matched than the first, still shows 10dB of difference at 20Hz. Taking the left channel as reference, the response is pretty much flat but overemphasized by about 8dB. This adds excess thump, punch and boominess, which could make the mix sound muddy.

Poor Mid Range performance. The only remarkable note here is the 20dB tilt favoring low-mid, which has a significant effect on the tonal balance of the QY9. It pushes the vocals and lead instruments to the back of the mix, by diminishing their clarity and presence, and instead adds a boxy and boomy quality to the overall sound.

Average Treble Range performance. Low-treble is underemphasized by about 6dB, which further reduces that clarity and detail of vocals/leads. Treble is performed evenly, and the peak at 9KHz is too narrow to be bothersome to most.

2.1 Soundstage
Show Help
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Error
Show Help
What it is: The average amount of deviation in Pinna-Related Transfer Function of the headphones, compared to that of a loudspeaker. Whether the soundstage is perceived to be unnatural, located inside or in front of the head, is dependent on this quality. The more the headphones activate the HRTF resonances of the ear (similar to what loudspeakers do), the more the soundstage will be pulled out from inside the listener's head. This quality affects both stereo and mono content.
When it matters: When a natural, in-the-front soundstage is desired, similar to that of a loudspeaker.
Good value: <5

Openness
Show Help
What it is: How open the headphones are, and how open and spacious they sound. This quality affects both stereo and mono content. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score.
When it matters: When an open, wide and roomy sound is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.

Acoustic Space Excitation
Show Help
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones takes some of the characteristic of its environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality affects both stereo and mono content. This value is the inverse of the Leakage test score.
When it matters: When an open, wide and roomy sound is desired.

Correlated Crosstalk
Show Help
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB
Noticeable difference: 0.3dB
:
0.01 dB

Poor soundstage. Due to their in-ear design, these earphones do not interact with the outer ear, and therefore their soundstage may be perceived to be located inside the listener's head. Also, these headphones noticeably isolate the listener from the environment, which results in a closed-up and small soundstage.

8.2 Imaging
Show Help
What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.

Score components:

The QY9 only isolate passively. Unfortunately, unlike the QY8, the seal that these in-ear headphones provide is not as good and therefore does not block as much ambient noise as the previous model. They will not fare well on loud, noisy commutes and you will be able to hear the train or the chatter of a busy office, if you don't listen to your audio at high volumes. Luckily, they barely leak at all and won't be audible to people around you even at the higher volumes.

The QY9 have a decent battery life for small wireless in-ear headphones. However, it won't be enough for, particularly long road trips as you will have to charge them at least once through the day especially if used continuously. Luckily they don't take too long to charge but you can't play audio while charging and they have no power saving feature, which means they will run out relatively quickly if left connected to your bluetooth device.
