[General Accessories] Alberto96:
These are the OVC H15 Noise Cancelling Earphones.

Unboxing

The packaging is huge considering the type of product, but it also contains a decent amount of accessories: 3x Black Earbuds (S/M/L sizes), 3x Transparent Earbuds (S/M/L sizes) one of which is pre-applied, 1x Micro-USB Cable for Charging, 1x Airplane Audio Adapter, 1x Magnetic "thing" (don't know how to use it sincerely), 1x User Manual and 1x Booklet. Everything contained in a soft pouch.

Of course the product itself is included, but i would have appreciated a 3.5mm Splitter for PC usage since it uses one plug for both Earphones/Microphone.

As regards the build quality, i am literally impressed. First of all, the whole cable is Nylon-Braided, and doesn't feel cheap at all.

The other most important thing is that they did not choose to use any glossy surface. I am pretty sure that there are many users who prefer the shiny and smooth surface just to look better, but i prefer matte surfaces for two reasons: 1) don't get scratched so easily 2) can't be a fingerprint magnet.

Starting from the heart of the device, the Noise Cancellation hardware is contained in a small box just after the 3.5mm plug. It is rechargeable, and has a simple Power Button together with two LEDs that indicate Power/Battery Level. Also, the front part, is made of Aluminum.

Going up to the controller, excluding the standard Volume+/Play/Volume- buttons and the Microphone, there is an interesting switch declared as "BASS".

Basically, it is a switch that increases the passthrough of low frequencies to each earphone. Does it work? Sort of. I'll talk more about this in the proper paragraph.

Something i find is worth to point out is the clip, i find it really useful to keep the microphone steady (avoiding it to get muffled). It's been a long while since i have seen a clip on modern earphones, good old times...

Each earphone has a pretty weird shape, but there is a reason for that. This shape follow the inside of the ear, in order to provide the best adherence. Great to avoid interference in windy conditions, but it keeps the ear slightly hotter than usual. Still usable in Summer though, tested with 36c in-room temperature.

Sound Quality

Sound Quality is pretty balanced. All frequencies seem to be handled properly, as long as you keep the Noise Cancellation hardware turned off for some reasons mentioned below.

Thanks to the particular/weird shape of each earphone, it is possible to get a pretty clean hearing experience almost every time, but the Noise Cancellation hardware improves it with no doubts.

It doesn't mean that it is perfect though, because, the BASS switch won't produce any noticeable difference with the NC turned on, and i guess there is a reason for this limit.

In order to isolate all other sounds, it is required to reorganize all frequencies isolating those related to the noise. Probably, this process reduces low frequencies too much and, as a result, they get cut for the most part.

Personally, not being a bass lover, i don't mind at all about this since i prefer clarity rather than ear-blowing bass, but it is still useful to know for those who are the opposite.

What you get is an overall balanced sound experience, with some compromises to consider.

As regards the Microphone, it seems to work as good as on all wired earphones, nothing important to report about it.

Conclusions

Nowadays Earphones/Headphones with Active Noise Cancellation are getting more and more common, especially this year, providing something that was available only on niche products (e.g. Bose products). This is what makes the high-tech market awesome. Day by day, expensive tech get cheaper and cheaper, and then implemented in affordable consumer products.

This is what happened with the OVC H15, it features almost everything that some years ago would have been considered niche-only. But, are all those features mature enough to be implemented this way? Probably yes, even though with some limitations such as the low frequencies cut-down that might be reduced with future revisions.

So, do i recommend this product? Sure, unless you are a bass lover.

P.S.: Battery Life matches the declared ~60 hours of runtime, so there are no reasons to talk about it in a dedicated paragraph.
