Excellent and work well with the app.

Exceptional quality, excellent external noise cancellation, very clear and full sound, undoubtedly a great product.

Good battery life, excellent noise cancellation, premium quality! Super satisfied with the purchase, I already had a Haylou S40, the quality is amazing. I believe it's good for physical activities (I'll test it out later).

The earphones are perfect, the battery is durable, they don't fall out of the ear, come with 3 size options of ear tips, control via the app for noise settings and everything else. Excellent purchase.

Come on: The ANC on this one works really well, I work in a noisy place and it eliminates those noises. Download the app and add the edit shown in the photo; it's from the audiophile channel: Mind The Headphone. It simply gives a new life to the sound and that's when it becomes sensational.

I give it 4.5/5
ANC 4.5/5
4/5 fit
Box and connection 5/5

First of all, regarding delivery and payment, it seems very good. Good price range and fast delivery.
I mainly use the Buds 4 Pro, and the noise cancellation seems to be about 70% of the Buds 4 Pro's level.
The sound quality is a sound that has sacrificed the density of the sound but enhanced the sense of volume.
The features of high-quality earphones include a rich sound quality that allows the mid-to-high frequencies to resonate at a comfortable level, almost as if you were standing half a step away from the sound source.
The Haylou N55 has a default setting that is V-shaped, but it's a weak V-shape while still maintaining a reasonable sound density.
I've tried various EQ settings, but it seems that setting it to a pop EQ among the basic EQs is the best option. It seems to achieve the most similar sound quality to the Buds 4 Pro. However, the sound as a whole does not sound as powerful and dense as the Buzz 4 Pro. Still, these earphones have significantly improved the phenomenon of masking in middle school and high school students while maintaining a comfortable fit. I think the role of the titanium-coated screwdriver is probably quite significant.

It seems quite impressive to achieve this level with a single driver.
Single-driver earphones, regardless of price, are generally difficult to achieve a balance between impact, volume, and density. That's why most low-priced earphones have an extreme V-shaped design.

It's one of two forms, and no matter what EQ settings are applied, it doesn't deviate significantly from this form.

The Haylou N55 has good levels of call quality, unbeatable battery life, comfortable fit, and noise cancellation. Considering the price range, it's definitely a five-star sub-earphone. As a flagship earphone, it seems quite good enough to recommend with four stars.

Its noise cancellation is very good. I bought it precisely because it has ANC and the same dB level as the Xiaomi Buds 5 Pro. It's similar but not the same, but it was worth the price I paid. As everyone knows, wireless earphones, regardless of the brand, ONLY LAST 1 YEAR due to their life cycles. So in a year, I will add an additional comment to this chat.

The phone does what is stated. Its ANC is very useful in noisy environments.

It has decent audio quality; I use a third-party equalizer app.

The audio during calls comes out clear.

The phone surprised me for its price. Very good!

Excellent phone, great sound quality, and very good connection. It arrived very quickly, I highly recommend it.

Excellent quality active noise-cancelling headphone model.

Everything is fine with the product; for the price, it's a very good purchase option.

The product comes sealed and complete, and it has excellent quality.

VERY GOOD, it's really worth it! Great battery, great bass, and the best part is the Noise Cancellation.

The headphones have very good build quality and sound quality. It has good bass and the volume isn't too loud (for me it didn't bother me because my other one was the Moondrop Space Travel, which also doesn't have a very high volume). .
The bad part about the Haylou that I received was the overly buggy software and the terrible app. I couldn't connect the app or recognize it most of the time, couldn't use LDAC or any other function of the app, nothing. But after two weeks, the headset received a firmware update (now version 1.0.3.6) and the app also updated, and everything is working fine for now. The phone connects quickly to the app, and I can use all the functions.
Tip: To use LDAC, you need to enable it in the Bluetooth settings of your headphones as well. (as shown in the photo)
Check if LDAC is also enabled on your phone in developer mode and in the Haylou app. (photos)

I bought it for an iPhone, the sound is decent, but I can't use HD audio with it, only with Apple products. The noise cancellation isn't that great, but if you press the earphone a little closer to your ear to seal it better, the cancellation will be more effective. Still, a good purchase.

Extremely high quality, highly recommended. Very good sound and the build quality and finishing are really excellent.
