  Grado GT220 wireless earbuds Building great earphones is a bit of a dark art. The goal is to create the illusion of a big, spacious sound out of something very small. Most of the time, earbuds can’t quite pull off this trick, so you end up with audio that can lack bass, sound tinny or seem distant (or in some cases all three). The GT220 wireless earbuds from the Brooklyn-based, family-run Grado avoids all of these pitfalls to make the most out of your music. The earbuds handle the big bassy electronic beats of Run the Jewels just as well as they delicate, breathy vocals of Nick Hakim. All the highs and lows have room to be heard. I suspect half the reason they sound so good is down to the fit. The earbuds twist into place with ease and sit there comfortably for hours, without any danger of falling out. There’s six hours of listening time between charges and another 30 hours of charge held in the case. There are plenty of extra features too, like wireless charging, touch controls and

  Vaonis Vespera smart telescope The notion of a telescope without an eyepiece to look through could inspire a few strongly worded letters from our readers, but we can’t help but lust after this beautiful new telescope from Italian company Vaonis (even if it does cost around £1,300). The Vespera takes the work out of stargazing. The scope takes the images hitting its sensors and sends a live-view to your smartphone or tablet via Wi-Fi. This means you can set up the telescope outside (it has a four-hour battery life), jump under the covers and tour the Universe. The app presents a list of cosmic points of interest to point the telescope towards, like the birth of a star, and the motors and GPS aboard the telescope point the lens in the right direction. From there you can watch the view live, take stacks of photos to reveal more detail and share what you’re seeing with friends. You can even schedule observations if you want to capture something while you’re asleep. Right now you’ll have

  Transparent speakers A  loudspeaker  is an  electroacoustic   transducer ; [1]  a device which converts an electrical  audio signal  into a corresponding  sound . [2]  The most widely used type of speaker is the  dynamic speaker . The sound source (e.g., a sound recording or a microphone) must be amplified or strengthened with an  audio power amplifier  before the signal is sent to the speaker. The dynamic speaker was invented in 1925 by  Edward W. Kellogg  and  Chester W. Rice  issued as US Patent 1,707,570. Apr 2, 1929. The dynamic speaker operates on the same basic principle as a  dynamic microphone , but in reverse, to produce sound from an electrical signal. When an alternating current electrical  audio signal  is applied to its  voice coil , a coil of wire suspended in a circular gap between the poles of a  permanent magnet , the coil is forced to move rapidly back and forth due to  Faraday's law of induction , which causes a  diaphragm  (usually conically shaped) attached

  Sony FX3 Sony’s FX3 is the smallest, cheapest cinema camera the company has ever made. It’s built for filmmakers, rather than photographers, so it can handle recording ultra HD video at 120fps for long periods. It comes bundled with a handle that’s ideal for shooting from low angles and it adds extra sockets for plugging in different audio inputs. There’s also in-body image stabilisation for when you’re “running and gunning”. The camera will also play nice with Sony’s yet-to-be-released Airpeak drone. At 715g, it’s a bit too bulky to fit in your pocket, but it’s light enough and small enough to take wherever you go. Keep an eye out for it in the hands of your favourite YouTuber soon.

  A   smartwatch   is a   wearable computer   in the form of a   watch ; modern smartwatches provide a local   touchscreen   interface for daily use, while an associated smartphone app provides for management and telemetry (such as long-term biomonitoring). While early models could perform basic tasks, such as   calculations , digital time telling,   translations , and   game-playing , 2010s smartwatches have more general functionality closer to   smartphones , including   mobile apps , a   mobile operating system   and WiFi/Bluetooth connectivity. Some smartwatches function as   portable media players , with   FM radio   and playback of digital audio and video files via a   Bluetooth   headset . Some models, called   watch phones   (or vice versa), have mobile cellular functionality like making calls. While internal hardware varies, most have an  electronic visual display , either backlit  LCD  or  OLED . Some use  transflective  or  electronic paper , to consume less power. They are
