Sony ICD-TX660 Digital Voice Recorder - Buy in Bangladesh

The Sony ICD-TX660 is an ultra-thin, pocket-sized digital voice recorder built for professionals, students, journalists, and researchers who demand high-quality audio capture in the most discreet and portable form possible. Measuring just 102 x 20 x 7.4 millimetres and weighing approximately 29 grams, the ICD-TX660 is one of the slimmest voice recorders Sony has ever produced — yet it packs a dual digital stereo microphone, 16GB of built-in memory for up to 636 hours of continuous recording, Linear PCM and MP3 recording formats, a 41% larger OLED display, One Push Recording, Auto Voice Recording, USB Type-C connectivity, and a built-in lithium-ion rechargeable battery. For buyers across Bangladesh who need a reliable, discreet, and feature-rich voice recorder for meetings, university lectures, field interviews, legal documentation, or personal notes, the Sony ICD-TX660 sets the benchmark for what a compact voice recorder can deliver.

Why the Sony ICD-TX660 Is the Right Voice Recorder for Bangladesh

Across Bangladesh, the need for dependable audio recording spans a wide range of professions and daily situations. Journalists and field reporters covering stories in Dhaka and beyond need a recorder they can slip into a shirt pocket and activate in an instant. University students at institutions across Dhaka, Chittagong, Rajshahi, and Sylhet need something light enough to carry all day and reliable enough to capture an entire lecture without manual intervention. Legal professionals, corporate executives, researchers, and government officers need a recorder that captures clear voice audio in challenging room acoustics without producing bulky, obvious equipment on a desk or table. The ICD-TX660 addresses every one of these requirements in a package that weighs less than a pen.

Key Features of the Sony ICD-TX660

Ultra-Thin Metallic Body at Just 7.4mm Thick

The ICD-TX660's defining physical characteristic is its extraordinary thinness — at just 7.4 millimetres deep, it is thinner than most smartphones and slim enough to fit inside the breast pocket of a dress shirt without creating any visible bulk. The full metallic body gives the recorder a premium, professional feel that matches its technical performance. Despite its small dimensions, every button and control is deliberately positioned for straightforward one-hand operation, making it practical to use in real recording situations where both hands may not be free.

Improved Digital Stereo Microphone with Parabolic Form

The ICD-TX660 features an improved dual digital stereo microphone with a mounted parabolic form that focuses incoming sound for enhanced sensitivity and directionality. The digital microphone design reduces background signal noise inherently without sacrificing sensitivity to the primary sound source — meaning voices, discussions, and presentations are captured with clarity even in acoustically challenging environments such as conference rooms, lecture halls, courtrooms, and outdoor settings. The stereo capture produces a natural, spatial sound image that makes recordings easier to follow during playback and transcription.

Auto Voice Recording for Optimised Vocal Capture

When the Auto Voice Recording mode is activated, the ICD-TX660 automatically optimises all microphone and recording settings specifically for vocal frequencies. This reduces the likelihood of capturing distracting background noise — air conditioning units, traffic outside, crowd murmur — while keeping the primary voice signal clean and prominent. For journalists interviewing sources in noisy public spaces, students recording lectures in large halls, or legal professionals documenting client conversations, Auto Voice Recording removes the need for manual microphone tuning and produces consistently usable audio without technical expertise.

One Push Recording for Instant Capture

The One Push Recording function activates recording immediately at the touch of a single button — even when the device is completely powered off. There is no need to navigate menus, select folders, or adjust settings before the recorder begins capturing audio. This is an essential feature for journalists and field workers who need to capture a spontaneous statement or unexpected development the moment it happens, without the delay of a multi-step startup process causing missed audio.

16GB Built-In Memory for Up to 636 Hours of Recording

The ICD-TX660 carries 16 gigabytes of built-in flash memory, providing enough storage capacity for up to 636 hours of continuous audio recording in MP3 48kbps monaural mode, or up to 5000 individual files across all formats. In Linear PCM 44.1kHz 16-bit mode — the highest quality format — up to 21 hours and 35 minutes of audio can be stored. In MP3 192kbps stereo mode, the capacity reaches 159 hours. For heavy users who record multiple meetings, interviews, or lectures daily across a working week, this built-in capacity means weeks of audio storage without needing to clear files or carry additional memory cards.

Linear PCM and MP3 Recording Formats

The ICD-TX660 records in two primary format types. Linear PCM at 44.1kHz 16-bit produces uncompressed, broadcast-quality audio with a frequency response of 95Hz to 20,000Hz — suitable for music recording, formal interviews destined for broadcast or archiving, and any situation where the highest possible audio fidelity is required. MP3 recording is available at 192kbps, 128kbps, and 48kbps monaural, with the lower bit rates extending recording time significantly at a modest reduction in audio quality appropriate for voice-only recordings such as meetings, lectures, and dictation.

Time Jump Playback for Fast Navigation

Finding the relevant section of a long recording is often as important as capturing the audio itself. The Time Jump feature allows the user to skip forward or backward by exactly 10 percent of the total playback time of any recording in a single button press. For a 60-minute recording, each Time Jump press moves 6 minutes through the file — allowing rapid navigation to the key moments of a board meeting, the important passage of a university lecture, or the critical section of a field interview, without slow manual scrubbing through the full timeline.

Large OLED Display — 41% Bigger Than the ICD-TX650

The ICD-TX660 features an OLED display that is 41 percent larger than the previous generation ICD-TX650, making it substantially easier to read recording status, file information, settings, and playback data at a glance. The OLED panel provides sharp contrast and clear text in both bright outdoor light and low-light indoor environments, so the recorder's interface remains readable regardless of where it is being used.

Top-Visible Recording Status LED

A dedicated recording status LED light is positioned to be visible from directly above the device — a deliberate design choice that allows the user to confirm recording is active with a glance downward, without picking up the device or repositioning it. Whether the ICD-TX660 is sitting flat on a desk during a meeting or tucked inside a shirt pocket during a field interview, the top-visible LED means recording status is always confirmable without interrupting the situation.

Noise Cut and Low-Cut Filter for Cleaner Playback

The ICD-TX660 includes a built-in Noise Cut function for playback that digitally reduces ambient background noise in recordings, making voices clearer and easier to understand when listening back — particularly useful for recordings made in noisy environments. A Low-Cut Filter is also available during recording to reduce the capture of low-frequency rumble from air conditioning systems, traffic vibration, and wind, keeping voice recordings clean from the moment of capture.

Digital Pitch Control and Variable Speed Playback

Variable speed playback allows recordings to be replayed at faster or slower speeds than the original without altering pitch — enabling rapid review of long recordings at increased speed, or careful transcription of fast speech at reduced speed. The Digital Pitch Control function adjusts playback pitch independently of speed, allowing additional fine-tuning of the playback experience for transcription work, language learning, or music reference.

A-B Repeat and Track Mark Functions

The A-B Repeat function allows any section of a recording to be looped continuously between two manually set points — useful for repeated review of a specific passage during transcription, study, or editing. Track Marks can be inserted into recordings manually during capture or playback, creating instant navigation markers at key moments such as agenda changes in a meeting, question and answer breaks in a lecture, or subject changes in an interview.

Voice-Operated Recording (VOR)

The Voice-Operated Recording function automatically pauses recording when the room falls silent and resumes when sound above a set threshold returns. This eliminates long stretches of silence in recordings from meetings with extended quiet periods, reducing file size and making subsequent review faster and more efficient.

Calendar Search for Fast File Retrieval

The ICD-TX660 organises recordings by date and provides calendar-based search, allowing users to navigate directly to all recordings made on a specific date without manually scrolling through a long file list. For professionals who record multiple sessions daily — journalists, researchers, corporate executives, and legal professionals — this is a practical time-saving feature that turns the recorder into a chronological audio diary.

USB Type-C Connectivity and USB Charging

The ICD-TX660 uses a USB Type-C port for both PC connectivity and battery charging. USB Type-C is the modern standard connector shared by most current Android smartphones, laptops, and accessories — meaning the same cable used to charge a phone or laptop can charge the ICD-TX660 without requiring a separate proprietary cable. File transfer to a Windows or Mac computer is handled directly via the USB connection, allowing recordings to be backed up, organised, and shared without any specialist software requirement.

Playback Compatibility: MP3, WAV, WMA, and AAC

Beyond its own recordings, the ICD-TX660 supports playback of externally loaded audio files in MP3, WAV, WMA, and AAC formats, expanding its usefulness as a portable audio player for reference recordings, foreign language material, or music files transferred from a PC.
