Trobla Review - de akoestische klankversterker voor smartphones

Trobla, the elegant amplifier for your smartphone

Charismatic, elegant and sustainable. The Trobla is unlike anything you’ve ever seen before. The wooden amplifier enhances the sound from your smartphone without making use of any electronics. Its chic design and warm allure make for a great addition to your interior.

Trobla’s origin

The Trobla was originally designed in Slovenia by Martin, Andrej and Matej. These three friends share a unique passion: creating original, stylish and sustainable furniture. Tok Tok is the company they built on hard work, dedication and a bit of help from Kickstarter.

The company’s title, Tok Tok, refers to the type of material that is used to create the Trobla: wood. Certified hardwood, to be precise, which is not only ecologically sustainable and responsible, but also gives the Trobla its warm and natural look and feel. In a world that is being dominated by electronics, this is a welcome change.

At first glance, it may look like a wooden speaker, but in fact the Trobla is an acoustic amplifier for your smartphone. What really stands out is the well-thought-out design, a result of the creators’ constant innovation and perfectioning process. And as we speak, the fourth generation Trobla is born into existence.

Trendy Slovenian design

The Trobla is a true work of Slovenian art. The five distinctive layers have been carved out seperately and the resonance box that is built at the inside of the amplifier can be compared to an acoustic guitar. It enhances the vibrations that are transmitted from the speakers of your smartphone, which creates the exceptional Trobla sound.

The multiple layers are serving a second purpose: they allow for placing several small magnets on the inside. The Trobla consists of two separate elements: the adapter and the base. The incredibly small, yet incredibly strong magnets ensure that the two elements remain steadily in place, even when you move, shake or throw your Trobla (although we do not recommend throwing objects through the room, obviously). The sound moves through the notch at the front of the amplifier and then, guided by the cone, travels smoothly through a hollowed chamber. The way Trobla is designed makes it similar to a music system sound box. The base of the Trobla is integrated in the body and can be easily pulled outwards. The magnet then ensures the base is fixed in place.

Walnut and Maple

The Trobla is available in two types of certified wood: walnut and maple, both suitable for every kind of interior. To create a shimmering finish, you can opt to apply a layer of beeswax. This won’t change the Trobla’s sound at all.

The walnut and maple versions not only have their own look and feel; they each produce a unique sound. Think of them as a Gibson and a Fender, two established names in the guitar industry that are synonymous with quality and class. Both sound a little different, but certainly remain equal in excellence.

Why Trobla is the best acoustic amplifier out there

1. Soulfoul sound

We’ve already mentioned many of Trobla’s features, but of course audio is the most important thing we’d like to discuss. The wonderful thing about the Trobla is that it doesn’t just amplify the sound coming from your smartphone. Its natural materials and intuitive design actually make for a soulful sound, creating a great vibe within your surroundings.

2. Great volume

When it comes to volume, we can assure you that this acoustic amplifier certainly lives up to its expectations. When playing something on your phone at a low volume (let’s say 25% of your phone’s maximum sound level), the sound is amplified from about 48dB up to 52dB. At half volume, the Trobla amplifies the sound from about 52dB to 62dB. And when playing something at full volume, the sound level goes up to at least 58dB to 68dB, and sometimes even up to 70dB. Did you know that the sound level is increased by a factor of 10 with each 10dB boost?

3. Compact

Weighing only 326 grams, the Trobla is fairly small and easy to bring along, wherever you go. Contrary to using Bluetooth speakers, no electrical chords or batteries are needed when you are using your Trobla; there’s no limit to the time you can enjoy your favorite music.

4. Excellent wood quality

Another practical advantage of the electronics-free Trobla is that you can always bring it with you to the pool or the beach. Of course, you could do the same thing with a Bluetooth speaker. However, a Bluetooth speaker can easily become damaged when accidentally splashed with water or when small grains of sand get through the housing. But if you bring your Trobla, there’s absolutely no need to be afraid of damage caused by water or sand. The woodwork will simply dry in the sun, and sand or mud can easily be wiped off.

Trobla Adapter

The adapter

Use an adapter to make sure that your smartphone remains secure when placing it on the Trobla. The adapter is the connecting piece that is placed between your phone and the Trobla. The adapter ensures that the sound is guided from your mobile phone into the sound chamber which produces the typical Trobla sound. Every smartphone has its own unique adapter. This is not only due to the thickness and width of your mobile phone, but also to the location, size and number of your phone’s speakers.

In order to use the Trobla, the speakers of your smartphone must be located at the bottom of the device. Adapters for the following phones are available:

  • Apple iPhone 4 up to and including the iPhone 7 Plus
  • Apple iPhone 6 (s) / 7 with Cover
  • Apple iPhone 6 (s) Plus / 7 Plus with Cover
  • Apple iPod Touch (fifth and sixth generation)
  • Samsung Galaxy S8
  • Samsung Galaxy S8+
  • Samsung Galaxy S7
  • Samsung Galaxy S7 Edge
  • Samsung Galaxy S6
  • Samsung Galaxy S6 Edge
  • Samsung Galaxy Note 5
  • LG G5
  • Nexus 5
  • Google Pixel
  • HTC 10
  • HTC One A9
  • Huawei P9
  • Huawei P8
  • OnePlus 3
  • OnePlus Two
  • OnePlus One

As you can see, the Trobla can be used for older phones as well as the latest models. Tok Tok will continue to make adapters for the next generation of high-end devices. So if the next generation of iPhones includes not one, but two speakers at the bottom, there will be a suitable Trobla adapter available in the foreseeable future.

How to guarantee the best Trobla sound

Although the Trobla’s acoustic sound quality is unmatched, we found a few ways to enhance the audio even more. Here’s four tips to get even better sound:
1. Don’t play your audio at full volume: the Trobla will increase the sound vibrations that come from your smartphone, so as you play your smartphone’s audio at full volume, the sound may become a bit harsh and shrill. That is why we’d advise to not play the audio coming from your phone at full volume. The best way to get a perfect, warm sound from your Trobla is to limit the volume to around 75% of your phone’s maximum capacity.
2. Don’t sit right next to the Trobla: instead make sure there’s a little bit of distance between you and your device in order to make sure you’ll be able to fully enjoy your music or videos.

3. Make sure to order a suitable adapter for your phone: every adapter is designed for a specific type of smartphone. If the adapter’s notches are too small, a considerate amount of the sound vibrations is blocked and you won’t be able to get the best audio possible. So if you do buy a new iPhone, make sure you get the right adapter. They are available for only 15 euros each.
4. Get an equalizer app for your smartphone: both the App Store and the Google Play Store offer a wide range of free and paid equalizer apps. These can help you control the output for each separate frequency. Too complicated? Of course you can always opt for the pre-programmed sound profiles on your phone.
