The package meets the price level.
There is no shortage of accessories. The package contains the following:
- HAYLOU W1
- Charging case
- USB Type-C cable
Build quality meets price standard.
The fit is good.
I tested it by connecting it to a Cayin N6II/E02 with aptX.
I don't know because I haven't been in crowds, but it is stable in the home. Distance tolerance is excellent, and the connection is seamless and intact even at a distance of about 5 meters. The music would be momentarily interrupted when a barrier was placed between us, but it would return after about 30 seconds and we could then listen to the music consistently.
There may be a small amount of background noise, but most people probably won't notice it.
The operating interface is a touch type.

REW Frequency Response
Sound quality description
The following review was tested on a FiiO M15 with an aptX connection.
HAYLOU W1 has a balanced sound signature that is almost completely neutral.
Please see here for detailed reviews on sound quality.
Lows / Bass
The low frequency range of the HAYLOU W1 is deep enough. It can also be said that the balance with the midrange is quite exquisite.
The bass drum kick has sufficient weight and depth, and the rumble is quite sure. The tightness is also good.
The electric bass also sounds sufficiently black and expansive.
For my personal taste, I would prefer a bass with a little more depth, but it is a good quality bass that will satisfy bass lovers quite well.
The midrange is adjusted fairly close to neutral. Texture is accurate, but there is a bit too much distortion and not enough clarity in the overall sound, so the overall sound is inferior in terms of resolution, flat, and lacking in three-dimensionality of instrumental sounds. Because of this, the realism of music, especially on live recordings, may be unsatisfactory.
The balance itself is good, so the listening comfort is stable, but there are a lot of incidental sounds, and the separation between the sound image and the background is loose, so the background may seem bright or the contours may be blurred.
On the other hand, the guitar edge may sound rich and attractive to some instrumental sounds, as the distortion tends to blur them with beautiful coloration.
Highs / Treble
High frequencies are at a good level of extension, with no lack of clarity, detail is heard quite clearly, and localization is quite accurate.
Consonant sharpness can be somewhat strong depending on the volume, but it is not noticeable due to the low resolution. However, the high frequencies generally sounded rusty and dry, although I am not sure if this is due to a lack of clarity, a little distortion, or both.
It can be said that this is an atmosphere that is common in balanced armature driver machines, so the sound may be familiar to the ears of those who usually prefer baland-armature drivers.
Sound quality general comment
- Original sound fidelity: A+
- Recommendation: A-
- Personal preference: B
The HAYLOU W1 is an entry-level fully wireless earphone with an almost perfectly neutral sound balance.
It is quite ambitious to use a hybrid configuration (and the BAs are made by Knowles) at a low price, but a little more distortion and lower resolution than its rivals may divide tastes.
For about the same price, the EarFun Air Pro 2 is probably a better value in terms of sound quality and features.
Sound quality features
- Excellent sound balance
- Excellent original sound fidelity
- Good texture
- Excellent localization
- Good high-frequency extension
- Good listening comfort
- Good focus on midrange
- Excellent sound image consistency
- Balanced armature driver-like dry sound (if prefer)
- Low resolution
The HAYLOU W1 is an ambitious product from a brand that offers a hybrid DD + BA configuration at a low price, aptX Adaptive codec support, and well-balanced sound. The overall standard does not seem too bad, except that it lacks in resolution and all music sounds flat and easy to hear.
