¿Vale la pena un altavoz con entrada óptica en 2025?

Is a speaker with optical input worth it in 2025?

The world of speakers continues to advance rapidly, with increasingly sophisticated technologies, but does it still make sense to include an optical input on current models? For those of us who value connectivity, as is the case with VULKKANO, this option remains relevant, as it can be key to updating our sound systems and connecting speakers to our televisions and other devices.

However, before making a decision, it's crucial to understand what this feature offers and whether it truly fits with the technological options available today.

What is optical input?

Optical input, also known as TOSLINK or S/PDIF (Sony/Philips Digital Interface), is a digital connection that transmits audio through light instead of electrical signals .

This connection is widely used to transmit high-quality audio between devices such as televisions, Blu-ray players, video game consoles, and sound systems.

Optical or Coaxial: Which is the best option?

When it comes to digital audio connections, optical and coaxial are two very common options, but what's the difference and which is best for today's audio?

  • Audio Quality : Both optical and coaxial connections transmit uncompressed digital signals, meaning they can both deliver excellent sound quality. However, some tests have shown that signal quality is slightly more stable over optical connections, especially over long distances. This is because optical signals travel through light, while coaxial signals travel through electrical signals, which can make coaxial signals more susceptible to interference.

  • Compatibility and Availability : Optical (TOSLINK) input is commonly used on TVs, video game consoles, and sound systems, while coaxial input, although present, tends to be less common. However, if you have a high-end audio system, you may find that the coaxial input is present, as it's a robust option and more common on professional equipment.

  • Durability and Flexibility : Fiber optic cables, being more fragile than coaxial cables, can be more prone to damage if not handled carefully. On the other hand, coaxial cables are generally stronger and more durable, making them a practical choice if you plan to move the cable frequently.

  • Cost : Coaxial cables are typically cheaper than optical cables, which may be a factor to consider if budget is a concern.

Optical connection vs other connections

In 2025, speaker connectivity options have expanded. In addition to the optical input, modern speakers, like those in our ARC or T range, often offer HDMI ARC (Audio Return Channel) connections , Bluetooth, Wi-Fi, and sometimes even USB inputs. Each connection type has its advantages, and it's important to evaluate whether the optical input is still the best option for your needs.

  • HDMI ARC: This is probably the most modern and convenient option for connecting video devices (such as TVs) to speakers. The main advantage of HDMI ARC is that it not only transmits high-quality audio, but also allows you to control the sound system volume via the TV remote . Additionally, with HDMI eARC (Enhanced Audio Return Channel), you can enjoy advanced audio formats like Dolby Atmos, making HDMI ARC a superior choice if you have a high-end sound system.

  • Bluetooth and Wi-Fi: These connections are ideal for those looking for convenience and flexibility , especially for listening to music from mobile devices or streaming apps. While they don't achieve the same sound quality as wired connections, they are a convenient and affordable alternative.

Who should consider an optical input speaker in 2025?

Although optical input is no longer the most advanced option, it can be useful for certain users:

  • TVs without HDMI ARC: Some older TVs or budget models may not have HDMI ARC capability. In this case, the optical input can be an excellent alternative for connecting a sound system without sacrificing too much audio quality.

  • High-fidelity audio equipment: If you have a dedicated sound system that doesn't include HDMI, or you prefer to maintain sound quality in its purest form, a speaker with an optical input may be the best option. Since the signal isn't compressed, it can be a solid choice for those looking for the best quality in their audio transmissions.

  • Simplicity and stability: If you don't need all the advanced features of HDMI or Bluetooth and are just looking for a robust and easy-to-use connection, the optical input is sufficient.

Should you opt for a speaker with optical input?

While optical input is still useful in some contexts, in 2025, audio technology has advanced significantly and offers more options. If your TV or audio device, like most of our speakers , has HDMI ARC or eARC, this is likely the best option for you. However, if you have older devices or prefer uncompressed audio quality , a speaker with optical input may be a valid choice.

In short, optical input isn't going away, but it's not the only viable option in 2025. It will depend on your current setup and your priorities regarding sound quality and convenience.
