The Pamu brand belongs to Padmate and includes a series of wireless headphones and charging solutions in its portfolio. The most recent novelty that has just hit the market are the Pamu Slide 2with characteristics that really set them apart in this segment.

After a few weeks of testing, we let you know all the details of these earbuds.

General specifications of Pamu Slide 2 earbuds

Pamu Slide 2 earbuds come equipped with an audio SoC that supports AAC and SBC codecs, integrate Bluetooth 5.2 and TWS technology. Thus, it is possible to listen to the contents synchronized with the image, without delay, as if they were wired headsets. The maximum range is 15 meters.

Pamu Slide 2 offers active noise cancellation up to 45dB. According to the manufacturer, an autonomy of at least 6.5 hours is promised for the earbuds, and can reach 26h of use using the battery in the box, with each earbud having a battery of 45mAh and the box 450mAh. The charging box, in addition to receiving power through a common USB Type-C cable charger, can still be charged through a wireless charger.

The speakers are 10mm and 32ohm impedance. Each earbud weighs 5.8g, where the total weight, with case, is 66g. They are IPX4 certified, splash, sweat and rain proof.

In the box

The Pamu Slide 2 box includes the headphones, inside the transport and charging case.

It comes with a quick instruction manual (with Portuguese language included), the charging cable (USB/USB Type-C) and a black carrying case. In another small box are the various rubber ear adapters. The right choice of these rubber inserts is essential for effective active noise cancellation.


The Pamu Slide 2 has a capsule-like design measuring 27 x 22 x 25.5 mm. The model under review is in dark blue and black with a shiny, pearl-like finish, but can also be found in white/black and green/black.

The brand's inscription is found in a circle on the outside, a tactile area that allows you to carry out some commands, such as answering calls, advancing with songs, stopping or playing multimedia, increasing and decreasing the volume, among others.

As already mentioned, the rubber that fits in the ear can be changed for better comfort and, essentially, to seal the entrance of external sound in the ear.

There are then three microphones, one feedforward, another feedback and another that will then capture the voice for calls. This microphone array is essential for keeping calls clear and helping with active noise cancellation.

An important feature is the inclusion of a proximity sensor in the area that touches the ear in order to start or pause content playback whenever the headphones are removed.

Active noise cancellation (ANC)

About the ANC, Padmate mentions that the Pamu Slide 2 are capable of eliminating up to 45 dB in low, medium and high frequencies, in a noise reduction bandwidth of 20-2000Hz. These values ​​are not possible to confirm with the tests carried out and, therefore, the comparison with other models is essential.

Of the various Samsung and Tronsmart models that I tested recently with the same feature, the effectiveness of the ANC of the Pamu Slide 2 is undoubtedly the most effective. When testing the Pamu Quiet Mini this had been a point that had even disappointed, but in this new version the brand managed to improve this aspect in an excellent way, remembering that the Samsung option used as a comparison is positioned in a higher range.

In addition to active noise cancellation, there is still a Transparency mode. This mode is ideal for chatting with people without having to take off your headphones, or simply being aware of the surrounding sounds. This one is also effective and works as expected, although I'm not very adept at using this mode. I still prefer to take off the headphones to talk to other people.

The PaMu mobile application

For a more complete use of earbuds there is an app dedicated to Pamu. Once installed, just add the device, which must be previously paired with the smartphone.

In the app's settings, the battery level of each headphone is available, it is possible to define what each touch button does and even choose between the original or game sound modes.

The Application, however, still lacks some improvements, although the headphones work perfectly without application.

touch control

Touch controls can be adjusted through the app, but by default one touch allows you to start playback and pause multimedia content and answer and hang up calls. Two taps on the left go to the previous track and two taps on the right go to the next track or reject calls.

Swiping up and down increases or decreases the volume. A long press on the left calls up the voice assistant and a long press on the right switches to ANC mode.


For the Pamu Slide 2 to start playing sound, just take them out of the box, wait for them to appear in the smartphone's Bluetooth synchronization and turn on. The app is not required for it to work. The application is just to provide you with extra options.

Then, as soon as they are removed from the box, the connection is immediately made. Thanks to TWS technology, they can be used individually or together without any problem. In addition, they can be independently connected to two different devices.

In terms of autonomy, they provide about 6 hours of music playback. A value that confirms the brand statement. It is important to mention that it will depend on the volume and in my use case it is always around 20/30%. The box allows for 3 more complete uses without recharging.

The Pamu Slide 2 also provide good quality reproduction and sound capture during calls, with a clear reduction in noise.


You Padmate Pamu Slide 2 earbuds are available on a Super Early Bird sale, with a 50% discount, for a price of €75.95 ($79), valid until the 8th of July. It also offers a Padmate magnetic smartphone holder.

The "Slide" concept is provided by the box that opens and closes with a simple slide. The box with its wireless charging capability adds even more value to the Pamu Slide 2.

When testing products in this price range and from less popular brands there is always the fear that the sound quality will suffer, but what we conclude is that, in fact, this is not the case. The sound quality is quite balanced in terms of bass, mids and treble and, above all, there is no sound distortion when the volume is turned up.

Calls take place with great quality and without the need to have both headphones on, but it was the active noise cancellation that most impressed, especially when compared to other products of the brand and competing brands, with products of higher ranges.

The proximity sensor, considering that I'm used to it, proved to be once again essential when using it. A detail that may still need to be improved is the reliability of the mobile app, which showed some flaws during use.

Pplware thanks Padmate for providing the Pamu Slide 2 earbuds for review.
