Featuring dual-mic Environmental Noise Cancellation (ENC) for use in loud environments, the Hollyland Solidcom C1 Pro-6S is a full-duplex wireless DECT intercom system engineered to provide clear audio and all-day wearing comfort in a true-wireless design with no bodypack or hub required. This configuration includes 6 single-sided headsets, 1 master and 5 remotes, along with rechargeable batteries, a charger, and accessories. The system transmits in the 1.9 GHz spectrum and uses proven DECT 6.0 technology to ensure secure and reliable transmission at a line-of-sight range of up to 1100'—making it well suited for a variety of applications including film/TV production, concerts, and live events.
Dual-Mic Environmental Noise Cancellation
For clear communication in loud environments, engage the dual-mic ENC (Environmental Noise Cancellation) feature. The ENC algorithm combines the main directional microphone at the speaker's mouth with a secondary omnidirectional environmental mic on the earcup to cancel out unwanted background noise for more intelligible speech. The microphone's wide 150 Hz to 7 kHz frequency response ensures detailed voice capture to keep your team working efficiently.
True-Wireless Self-Contained Headset for 2-Way Communication
With no beltpack or base station, the C1 Pro offers a highly portable and hands-free coordinating experience for media production teams and others looking for real-time voice communication at line-of-sight distances up to 1100'. The Pro version offers increased portability and durability over the original, while the single-ear headset design is dust and water resistant and designed to provide a comfortable all-day wearing experience.
Easy to Use
A long press on the "A" button on the master and remote headsets is all it takes; the headsets pair up in about 10 seconds and you're good to go. The microphone boom on each headset rotates 360°, allowing for left or right orientation. Rotating the boom arm up or down conveniently mutes the mic when not in use. Alternatively, the mute button on the earcup can be set to mute or push to talk, depending on the user's preference. An LED indicates the system is working and warns you when the battery is low.
Rechargeable Batteries + Charging Station
Each headset runs on a single rechargeable battery. The amount of battery time in the master headset depends on the number of following headsets in use; with 1 to 5 remote headsets connected and the ENC features engaged, the battery will last for approximately 5 hours; with up to 7 following headsets in use, the battery life is 4 hours. Each remote headset will last for up to 10 hours on a single battery charge with the ENC engaged. Each battery fully recharges in 2.5 hours and a battery charging station, USB cable, and AC adapter are included.
Expandable and Backwards Compatible
The Solidcom C1 Pro system allows you to link up to 7 remote headsets to the master headset without using a hub. The C1 Pro HUB Base (available separately) lets you use up to 8 remote headsets at once. The C1 Pro is backward-compatible with the Solidcom C1 system. Note that the ENC technology functions by removing the environmental noise at the speaker side. Whether you're wearing a C1 or a C1 Pro, the environmental noise you hear will be significantly reduced as long as the sound is coming from a C1 Pro headset.

Excellent introduction
Format: Kindle
This is a well-written introduction for quickly learning how to use Ollama to run LLMs on your local machine. The book is light on theory but very good for facilitating hands-on experimentation. Only minimal Python experience is needed. Contrary to another reviewer's comment, the source code, which can be copied from the Kindle version of the text, is also readily available by emailing the author at the address provided. The final exercise in the book leads you through generating a RAG application to use Ollama to process your own documents without having to make them available to an external server.

Lim has written another really clear, easy-to-follow tutorial. This one walked me through the Ollama platform showing step-by-step how to download open weight models, query them, supply them with my own documents, and write applications that are powered by LLMs. Lim provides an easy-to-follow path to get the first version of an LLM-powered app up and running.
