What makes a good sound system? We will get different answers depending on who we are asking. Sound quality is a subjective matter based on choice and preferences. But there are some parameters which are common and form a base of a good-quality sound system. Loudness, clarity of sound and fidelity are among the three main components of a good sound system. Sony has years of experience and expertise in delivering among the best-sounding audio systems. These are the people who had invented the Walkman! The Sony GTK-N1BT is a futuristic looking one-box speaker system which is ultra-portable and a truly unique design.

It has LED lights which light it up to give it a different look. It features Bluetooth and NFC connectivity. The Sony GTK-N1BT is available at a price of Rs. 16,300/- in stores. Let us take an in-depth look at this unique speaker in this review.


At the first glance, the Sony GTK-N1BT looks nothing like a speaker. Incredibly, the first thought that comes to mind after looking at it is that it is a projector. The built-in subwoofer which is placed right in the middle looks like the projector’s lens. The big subwoofer has a black speaker grill made up of drilled holes. It is ringed by a chrome accent which further serves to enhance the illusion of a projector. The subwoofer is flanked by two full-range speakers, one on each side. They feature the same round design as the subwoofer with identical black speaker grills and chrome rings. The speaker box is built out of acoustic-friendly materials which further enhance the sound quality. There are six multi-colour LED lights included in the speaker; two inside the subwoofer’s grill and four on the outside around it.

Sony GTK N1BT Portable Bluetooth Speaker Design

These light up in ten pre-programmed combinations or can pulse according to the beats of the track currently playing. The corners of the speaker, at the front side are sliced in a cross section, giving the front face a diamond like look with multiple facets and edges. This gives the speaker a very unique look. There’s one more unique thing about this speaker; it can be placed either horizontally or vertically, depending on the available space. When it is placed horizontally, the top-right facet houses the NFC connectivity system and it is marked so with the NFC symbol. In the horizontal position, the right side of the speaker houses the control panel. It has a big LED display and a big rotary volume control button. The rest of the buttons are digital. The Sony GTK-N1BT features a host of connectivity options which include; a USB port, a 3.5mm headphone jack and an analogue Audio Line In jack. It also includes an FM radio and wireless connectivity over Bluetooth. All-in-all, the design review of the Sony GTK-N1BT highlights the unusual design and futuristic look of the whole system.


The Sony GTK-N1BT comes in a really unique body casing. The one-box form factor means that all the speakers in this speaker system are enclosed in one cabinet which is ultra-portable. The Subwoofer in the middle outputs at a peak performance of 60W and the two full-range speakers output at 20W each, giving this speaker a combined peak output of 100W. It has five preset equalizers; R&B, Rock, Pop, Hip-Hop and a Flat equalizer setting. The bass output is really punchy and it is well balanced by the mids, highs and lows from the full-range speakers.

The Sony GTK-N1BT features S-Master R digital amps for clear highs. The LED lights add nothing to the audio performance of this system, but it manages to make the speaker futuristic and cool.
