The 48-hour IEM

It’s taken a while for the miracle workers in audiophilia to create an actual Airpods Pro competitor that’s priced more like a nice steak dinner, but they’ve done it. The Tanchjim Echo is a Bluetooth 5.2 IEM that boasts intelligent touch commands, aptX adaptive Bluetooth, a combined 48-hour battery life, and more.

Comfortable and stable

The physical shape of the Echo is the result of hours of research and many modifications. Informed by the angle of the auricle and the tragus, its ergonomic design sits snugly in the ear without causing discomfort.

Warm light

Unlike many Bluetooth charging cases, which use annoying and overly bright blue lights, the Echo uses a warm-colored soft light that “breathes” to indicate charging.

A variety of ear tip alternatives

The Echo comes with special customized short ear tips to meet the needs of users with small ear canals. The ear tips are made of skin-friendly silicone with a frosted surface, which is more comfortable and further enhances the wearing experience.

Stable connection

The triangular signal antenna designed according to the shape of the ECHO cavity can transmit signals to all parties without being blocked easily, providing a stable Bluetooth signal connection.

Bluetooth 5.2

A Qualcomm QCC3040 chip supports Bluetooth codecs like aptX, aptX adaptive, AAC, and SBC.

High-quality voice

The Echo uses precisely angled microphones that record vocals quickly and clearly, effectively improving vocal clarity under ENC noise cancelling.

Low latency synchronization

Never experience laggy audio or images again thanks to Bluetooth 5.2. AptX adaptive decoding technology provides smooth performance, higher stability, and keeps audio and images in real-time synchronization.

Intelligent touch commands

Use easy-to-remember touch commands on the outer shell of the Echo earbuds and keep your phone in your pocket. By simply tapping on the left or right earbud, you can play/pause the music, go to the next or previous track, answer or reject calls, or activate your phone’s voice assistant.

6H + 42H battery life

Rock on for a combined 48 hours. Each earbud has 6 hours of battery life, while the charging case has another 42 hours. When the charging case is dead, recharge it via the USB type-C port or a wireless charging pad or dock.
