with Bluetooth and USB-C. And it comes at the best time

The physical format is immortal (unless ask PlayStation, of course) and what we have been seeing for some time is that not only are the formats that never really ended up coming back, but there is also the trend of retro hardware to play those formats. We are talking about digicams to take photos without the algorithms of a current mobile phone, but also about vinyl players. In video games, retro consoles have been a fantastic way to enjoy video games for years (and even more so now how the current generation is getting), there is nostalgia for VHS and it was another format that seemed forgotten: that of tapes or cassettes. Because it’s not just that you can find tapes at a good price, but there are a lot of players (misnamed ‘Walkmans’) that have adapted to the new times with lithium batteries and Bluetooth connection. And the most important thing is that, despite all the limitations of listening to music on CD, tape or vinyl, this is something that makes perfect sense if we want to disconnect from the algorithm and actively listen to music. Retro is back (and perhaps at the best time) The Walkman is today a collector’s item. I am referring to the legendary Sony TPS-L2 that hit the market in 1979. Since then, the Japanese brand’s player became a standard on which they were iterated both inside and outside of Sony itself. Improvements soon came with miniaturization and the WM-2, as well as the production of similar devices by other brands such as Aiwa or Sanyo. Legendary However, the CDs did not take long to arrive and Sony had to reinvent itself with the Discman. In fact, he had to reinvent the Walkmann itself and, already in the digital age, launched a line of devices to play MP3 and uncompressed files under the Walkman brand. It is much more convenient to have an entire library in your pocket and not need to change batteries, where does it end up. But it’s much better to have all the world’s music within reach of a data connection. With platforms like Spotify, Tidal, Apple Music and othersit seems that an MP3 music player does not make sense, much less a device as limited as a tape or cassette player. However, Starting in 2018, things began to change.. That year we began to see a rrise in sales of music on cassettesbut also companies that turned their blank tape production plants back on so that users could do the reverse digitization process: from their MP3 music to the cassette. The idea is clear: in front of the algorithm and having music as a mere companion, as if it were white noise, recover control and experience, active listening. I recently started collecting vinyl and, although I still I have to decide on a playerYes, I have started listening to most of my music on an MP3 that I bought. It’s a SnowSky Echo Mini from the FiiO brand, a company that is focusing on audio devices and that not only allows you to read high-quality files, but also takes up very little space, the battery lasts a long time and there is no algorithm controlling my listening: only my music. I have been thinking for some time about taking another step and take that portable experience to an even more physical plane: that of the aforementioned cassettes. FiiO has a player and, really, it is not a lonely animal in this market. You just have to go to Amazon to see that there are many ‘walkmans’ to choose from and that also have modern features. It all depends on how much you want to spend, since you have models like the ones my colleagues point out, which range from those that for 20 euros allow you to play and convert to MP3, to one of Energy System very basic, but with a retro design, passing through much more expensive models like the We Are Rewind made of aluminum or those mentioned from FiiO. As with any device, it all depends on what you want to spend. And yes, you can always go to the second-hand market for a real Walkman, but there you will still have to dig deep and you won’t have features like a battery or Bluetooth. Be careful, I’m one of those who thinks that since you’re here, it’s better without Bluetooth, but having it doesn’t hurt. In the end, it is clear that there is an interest in this and, in fact, we have companies like Medion bringing out ‘parrots’ with a lot of functions. My recommendation, if you are even remotely interested in getting into the possession of music, not depending on an algorithm or that tomorrow the company on duty will take away songs from your face (which happens), take a look at second-hand stores because the tapes can still be found at a fair price. My partner Tones, of course, He is very cool with this topic. Image | We Are Rewind In Xataka | Special defeated technologies: Laserdisc

I have tested the Logi Dock, the combination of USB-C hub, speaker and microphone for video calls. It’s a sum that makes a lot of sense.

I have been working from home for nine years. It wasn’t long ago that I realized that my laptop, a 2021 MacBook Prois the answer to a question that no one has ever asked me: “what do you want, power or flexibility?”. I answered flexibility, but I didn’t know until it was too late. The MacBook Pro is always on the table, but sometimes it also travels or I take it to the cafeteria when my head demands a different environment. It is a desktop computer that from time to time has to go outside. Logitech, who knows a lot about peripherals and how we work, has understood this very well. The Logi Dock is not just a hub of ports to compensate for the fact that recent laptops are not as generous in ports. It is a value proposition that goes beyond: it is an operations center that stays on the desktop while the laptop comes and goes. One USB-C cable to connect everything when you arrive, one to disconnect everything when you leave. That, in practice, has a higher value than what appears on a specification paper. Behind the dock there…: HDMI 2.0 (4K, 60Hz, HDR). DisplayPort 1.4 (4K, 60Hz, HDR). 2 USB-A (USB 3.1 at 5 Gbps). 2 USB-C (USB 3.1 at 5 Gbps) 1 extra USB-C on the side with 7.5W fast charging. and USB-C upstream dedicated to 100W for the laptop. All in a single connection strip that you never touch again. What it does not have is Thunderbolt, Ethernet or card reader. View of the ports of the Logi Dock. A side USB-C is missing, designed primarily for charging the mobile phone. Image: Xataka. There’s that USB-C on the side. Image: Xataka. Immediately the most important question about this product appears, which deserves a completely honest answer. A hub USB-C generic costs between 30 and 80 euros. This dock right now it costs from 276 euros on Amazon. What justifies paying five or ten times more for the Logi Dock than for a simple hub USB-C? That’s the gist. The short answer is that it depends on whether you need what’s extra, not whether you appreciate what’s equal. Ports are ports. What sets the Logi Dock apart from any other hub random are two things: the speakers and the microphone. And that changes the equation… for a specific user profile. In my case, I have had it connected to the MacBook Pro M1 Pro and the Huawei MateView 28 inches. Keyboard, mouse, Scarlett 2i2 interface with the Rode PodMic for the podcastand charging the laptop at 100W. A cable from the Mac to dock. Everything resolved. I start with what does not have a hub anyone and it does have the Logi Dock: the speakers. My Huawei monitor has a built-in speaker that does the bare minimum. And those on the MacBook, which stays closed to one side, are “trapped.” With a hub Generic would have solved the connectivity, but not the audio: the Logi Dock provides good speakers and a microphone designed to not sound boring during video calls. The buttons are designed to be used as quick access during video calls, and also to join them directly with Logi Tune. Image: Xataka. Image: Xataka. The Logi Dock’s 55mm drivers with their side-mounted passive radiators produce full-bodied sound, some bass, and enough clarity to listen to music while working. It is not an audio monitor. But it doesn’t pretend to be either. In the video calls in which I have used them, giving up the headphones, the microphone beamforming six capsules works well. My interlocutors do not complain and background noise is reasonably attenuated. The real argument for the Logi Dock is not that it is the best at anything, but that He’s good enough at everything at once. The texture of the fabric mesh, in macro photo. Image: Xataka. Three months of use have also shown me where it is weak. No Thunderbolt, no Ethernet, no card reader… The touch buttons on the top panel work fine, but calendar integration via Logi Tune is the most dispensable part: with the Mac you already have your notifications, and join a meeting with a tap on the dock It is a shortcut that in practice you almost never use. It sounds like a function forced in to reinforce its proposal and better justify its existence. In my opinion that value is not there. What you do use, every day, is the most difficult to quantify: the absence of friction. He dock It’s been plugged in for months and has never given me a single problem. does not ask drivers to reinstall or annoying updates, the ports work well and there is no audio that is lost when waking the Mac from sleep. Is it worth paying five times more than a hub generic? If your desktop already has good speakers and a microphone, or if you simply prefer using headphones, probably not. Buy the hub cheap and you will save. But if in your case the Logi Dock becomes the only real speaker on the desk, the microphone in meetings and the only cable that connects and disconnects the laptop every day, then the comparison is no longer with a hub of 60 euros. It is with “a hub “more speakers, more microphone, plus the convenience of everything coexisting without conflict in a single block.” And that last comparison is won by the Logi.

There is an invisible chip in every USB-C cable that decides whether your phone charges fast or slow: almost no one knows it exists

There is a small and notable chip in our USB-C cables. This is the so-called “e-Marker”, which is especially important. The reason is simple: when we connect a cable to a device, it is responsible for indicating to those devices whether the cable supports more or less transmission or charging speed, for example. USB-C chaos is a little less chaos. USB-C connectors completely dominate the market, especially after European regulations that require them to be used to charge mobile phones and other devices. Although they have become the Swiss army knife for connecting all types of devices and peripherals, it is not easy to know what we can do with a cable when we connect it to our mobile phone or laptop, for example. And that’s where the e-Marker chip (Electronically Marked ID chip) comes in, a fundamental yet invisible component of the connectivity of our devices. In Xataka We criticize the EU a lot with its obsession with regulating Big Tech. There are at least two examples that justify this obsession A chip to identify everything. The official specification of the USB-C standard clearly indicates the mission of this chip, which is responsible for showing what capabilities the cable in question has. The document that talks about this chip is the one dedicated to USB Power Delivery, the power delivery function through these cables. Specifically, the identification data includes: Manufacturer and model of the cable. Signaling protocol: that indicates the maximum transmission speedthat is, if it is a cable with USB 2.0 support, or USB 3.2 of one generation or another (Gen 1, Gen 2, etc.). Active construction (in long cables there may be chips that regenerate data signal to act as a kind of repeater) or passive construction (they do not alter the data signal). How much power does the VCONN pin (intended to power accessories) consume? Whether the cable can support 3A (standard) or 5A (required for powers from 100 W to 240 W). Latency (signal delay over the cable). RX/TX directionality (how the high-speed cable pairs are configured). SOP Controller Mode: Whether the cable controller can communicate independently with the charger or device Hardware/firmware version. One of the sections of the USB Power Delivery specification that talks about this chip. Source: USB.org An active safety mechanism. The e-Marker is not only official, but is a mandatory part of the USB Power Delivery (USB-PD) specification dictated by the USB Implementers Forum (USB-IF). This chip acts as an active safety mechanism, and during the power negotiation phase, the chip tells the charger “I am a cable certified to support up to 100W” (for example). If the charger does not receive that digital confirmation, it will assume that the cable is basic and cheap, restricting the flow of power or data transmission. Does your phone charge slowly or is the transfer using pedals? In fact, if a USB-C cable does not have an e-Marker chip, most device drivers will automatically treat it as a USB 2.0 cable. That means that even if the cable is physically capable of more, the speed will be limited to 480 Mbps maximum, and charging will also be slower. With 3A you can reach 60 W at 20 V, so even so this section is not so affected and it also depends on the charging capacity of the charger. {“videoId”:”x8dmqaj”,”autoplay”:false,”title”:”One USB-C TO RULE THEM ALL- the European Union approves a single charger for mobile phones”, “tag”:”webedia-prod”, “duration”:”54″} The rails. High-speed cables (USB 3.2, USB4, Thunderbolt) have multiple pairs of copper wires designed to transmit data in parallel. The e-Marker tells the device “I have all the threads necessary to activate dual lane mode.” If this confirmation does not arrive, the transfer speed is again limited. The e-Marker on long cables. Another function of the e-Marker, as we said, is to identify the length of the cable. At high transmission speeds the signal degrades very quickly, and the e-Marker is responsible for notifying you, allowing the device (mobile phone, computer) to adjust the signal strength to compensate for potential data loss. Support for alternative video modes. Another option that this chip enables is to indicate what video connection standards the USB-C cable in question supports, and if, for example, it has the necessary bandwidth for 4K or 8K resolutions. There are “readers” of the information provided by the e-Marker chip, although they are not cheap: this one from ChargerLAB costs about 140 euros. Two key pins. The “brains” of a USB-C connector are located on two specific pins known as the configuration channel (CC). These pins (CC1 and CC2) allow, for example, the orientation or reversibility to be detected. Since the connector is reversible, the device needs to know which side you inserted the cable to activate the appropriate data pins (TX/RX). When connecting it, the side will be identified, and based on that the rest of the pins are switched for transmission. The other pin of the configuration channel becomes Vconn to power the e-Marker chip. In Xataka | Mobile phone manufacturers first stopped including the charger with every purchase.
