Elecom will release two models of in-ear, canal-type Bluetooth headsets, totaling 11 items, from early June 2026[1]. The headsets support HD Voice, which makes the most of VoLTE call quality, delivering voice as clear as a face-to-face conversation even in noisy locations[1]. The lineup consists of the standard LBT-HSC11 series and the higher-end LBT-HSC21 series, which adds a noise-reducing microphone. Both are designed to solve common workplace frustrations such as "it's too noisy to hear" and "my ears hurt after long use"[1].
Canal-Type Design for Clear Audio Even in Noisy Environments
At the heart of these products is support for HD Voice, which draws out the full call quality of VoLTE[1]. HD Voice is a high-quality calling standard that handles a wider audio band than before, making the other party's voice easier to hear clearly. The headsets also adopt an in-ear canal type angled to match the shape of the ear, and their ergonomic design improves both fit and the sense of a tight seal[1]. The improved seal reduces ambient noise, making speech easier to catch even in loud surroundings[1].
Comfort has also been considered. The ear hook has been redesigned from the previous model so it stays comfortable even during long use[1]. The headsets can be worn on either ear, and S, M, and L ear tips are included so users can choose their preferred fit (the M tip comes pre-attached)[1]. Beyond a wireless headset, they can also serve as a wireless intercom[1].
Standard "LBT-HSC11" vs. Upper "LBT-HSC21": The Microphone Sets Them Apart
The lineup is made up of two series with different capabilities[1].
The standard LBT-HSC11 series supports HD Voice for clear call quality[1]. It features a mic mute function that prevents your voice from reaching the other party during a call, and power is controlled by pressing and holding the front switch[1]. It offers up to about 55.5 hours of standby, about 12 hours of continuous talk time, and about 14 hours of continuous music playback, supporting extended use[1].
The higher-end LBT-HSC21 series adds Qualcomm cVc (Clear Voice Capture) on top of HD Voice[1]. This technology suppresses noise on the transmission side, delivering your voice to the other party in a clearer state[1]. It also features a large call button that is easy to press even for sudden calls, a dedicated mic mute button for quick switching at any time, and a slide switch that makes the on/off state easy to see[1]. It offers up to about 54 hours of standby, about 11.5 hours of continuous talk time, and about 14 hours of continuous music playback[1].
If you want clear calls at a lower price, the standard model fits; if you also value transmission quality, the upper model is the choice.
Multipoint and Intercom App Support for Everyday Convenience
The headsets are well-equipped beyond call quality. They support multipoint, allowing two communication devices such as a smartphone and a PC to stand by simultaneously, so you can switch the connection as needed[1]. The volume buttons handle volume adjustment as well as skipping tracks forward and back, and a single button summons Siri or Google Assistant[1].
Convenient everyday features stand out, too. The headset's remaining battery level can be shown on the smartphone screen, and status such as power on/off and pairing can be confirmed via Japanese voice guidance[1]. The headsets support the intercom app "Gurucam," and the "voice mic on/off" function lets you use the headset and smartphone like a transceiver[1]. Charging uses the increasingly common USB Type-C port, so they can be charged with the same cable as a USB Type-C compatible iPhone or Android smartphone[1].
The communication method is Bluetooth 5.2, with supported profiles A2DP, AVRCP, and HFP, and supported A2DP codecs SBC and aptX[1]. Charging takes about 2 hours, and the body weighs about 9.1 g, making it a lightweight, compact size suited for carrying[1]. Note that full compatibility with all connected devices, OS versions, and apps is not guaranteed, and Elecom advises against using the headset while driving or leaving it in a vehicle, as this may cause accidents or fire[1].
Pricing, Release Date, and Where to Buy
The release is scheduled for early June 2026[1]. The standard LBT-HSC11 series has a street price of 3,280 yen (2,982 yen excluding tax), and the higher-end LBT-HSC21 series is 4,280 yen (3,891 yen excluding tax)[1]. Colors are mainly four for the LBT-HSC11 series (black, blue, green, white) and five for the LBT-HSC21 series (black, gray, blue, copper, beige)[1].
Sales channels include Amazon.co.jp and the Elecom Direct Shop, and purchase pages for some model numbers are already available[1]. Both series are "THINK ECOLOGY" certified products that meet Elecom's in-house environmental certification standards, reducing the plastic weight of packaging by 20 percent or more compared with the company's reference products and moving instruction manuals to paperless form[1]. Detailed specifications are also published in Elecom's official news release[2].
