Featuring dual-mic Environmental Noise Cancellation (ENC) for use in loud environments, the Hollyland Solidcom C1 Pro-3S 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 3 single-sided headsets, 1 master and 2 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.

Cute necklace will be in high rotation
Color: T
I absolutely love this sunflower initial necklace! The moment I put it on, I could tell this was going to be a special piece in my jewelry collection. The combination of the delicate sunflower charm with the heart-shaped initial "T" is just stunning – it's feminine without being overly fussy, and the design feels both modern and timeless. I bought this as a gift for my sister-in-law, and she was genuinely touched by how thoughtful and beautiful it is. The white gold plating gives it an elegant shine that catches the light beautifully, and it's substantial enough to feel like quality jewelry while still being comfortable for everyday wear. The necklace itself is well-crafted with attention to detail – the sunflower petals have a lovely texture, and the initial letter sits perfectly within the heart shape. The chain length is ideal for layering with other necklaces or wearing alone, and it sits right at that perfect spot on your collarbone. I've been wearing mine regularly for a few weeks now, and the plating has held up wonderfully with no tarnishing or color changes. The clasp is secure and easy to manage on your own, which I really appreciate since I wear it daily. The style strikes that perfect balance between special occasion jewelry and something you can throw on with jeans and a sweater. I recommend this product because it's a genuinely well-made piece that feels personal and meaningful while being durable enough for regular wear.
