Sennheiser HME 26 S Professional Single-Sided On-Ear Broadcast Headset

The Sennheiser HME 26 S (Official Article Number: 700321) is a premium, lightweight single-sided (one-ear) closed-back supra-aural (on-ear) broadcast headset purpose-built for outdoor television, live radio reporting, and dynamic communication intercom environments.

The "S" designation specifies its single-sided frame layout, allowing commentators and operators to maintain direct acoustic contact with local venue cues, producers, or colleagues off-mic. The "E" designation indicates its high-performance electret condenser microphone capsule, which delivers an extended high-frequency vocal tracking curve comparable to standalone studio recording microphones.

Key Acoustic and Operational Attributes

  • Single-Sided Isolation Framework: Features a single active on-ear cup paired with a comfortable, non-padded secondary temple support arm on the opposing side. This layout keeps one ear completely free to monitor local environment cues, crowd atmosphere, or direct conversations without removing the headset.

  • Pre-Polarized Electret Cardioid Capsule: Outfitted with a high-transient, noise-reducing electret condenser microphone element ($40\text{ Hz}$ to $20,000\text{ Hz}$). Its cardioid pickup profile filters out ambient stage chatter and background city noise, delivering crisp and authentic vocal articulation.

  • Triple-Setting ActiveGard Hearing Protection: Equipped with a built-in protective ActiveGard limiting circuit. Accessible via an onboard switch mechanism, it lets operators choose between three protection thresholds (Off, 95 dB, or 110 dB SPL) to tame sudden incoming communication blasts or line feedback.

  • Flexible Left- or Right-Side Wear: The microphone boom arm rotates a full 270 degrees, allowing it to be worn on either the left or right ear. The temple stabilizer and active ear cushion naturally shift to align with the chosen side configuration.

  • Modular Cable-II Architecture Base: Ships directly from the factory without an attached cable. The headset features a specialized multi-pin connector socket at the base of the cup, enabling seamless integration with Sennheiser's Cable-II series (such as the XLR-3/1/4" combo or XLR-4F variants).

Field Configuration and Power Management Advice

Supplying Bias Power to the Electret Capsule: Because the HME 26 S utilizes a condenser microphone element rather than a dynamic one, the capsule requires electrical bias power to operate. When using standard combination cables (like the Cable II-X3K1), ensure that P48 Phantom Power is turned on at your audio console, camera body, or intercom base station. If phantom power is turned off on that channel, the single-sided headphone will still play audio perfectly, but the microphone will not register a signal.

Shock-Mount Management and Care: The electret capsule inside the boom head is protected by an internal mechanical shock-mount suspension array designed to absorb structure-borne noise, such as frame adjustments or cable rubbing. When adjusting the boom angle, handle it by the flexible mid-section rather than grabbing the microphone head capsule itself. This protects the internal suspension from being forced out of alignment over long production seasons.

Great little mouse for a low price
Color: Purple, Color: Purple
For about $10 this was a great little mouse! The buttons are super quiet and the shape seems comfortable. I work from home and I bought this as a last min I need it tomorrow kind of deal. I guess I should have looked into the description more as this is a tiny little mouse. I've gotten more used to it as the day goes on, but I am definitely ordering something bigger. This will make a fine little back up mouse though. PROS: Super quiet Adjustable pointer speed button Nice shape Accurate color CONS: Super tiny It goes into sleep mode a bit fast for me personally and then takes (what feels like) forever to wake back up again (probably about 30-45 seconds,

TECKNET Wireless Mouse, 2.4G Ergonomic Optical Mouse
Color: Purple
Worked right out of the box! I purchased TWO because I am always knocking it to the floor, which is why I believe my original one (designed just like this one, same color, (my favorite color), different company, G*** H***), stopped working properly, and the fact that I was starting to change the batteries about once every two weeks! There are some subtle differences from my previous mouse, like, the wheel light is not as bright, and the light on the bottom doesn't seem to light up, unless it does, only when the mouse is in motion, on a flat surface. Anyway, so far, so good! I would recommend!

Grab yourself a bargain!
Color: Purple
For those unfamiliar with Tecknet products, brace yourself to be amazed! This multipurpose mouse is an excellent purchase for all. Are you looking to get rid of your annoying wired mice? Look no further, you won't have to waste space anymore for that wire going across your desk. This wireless mouse is especially useful for notebook users, since it is lightweight allowing you to stay flexible on the go with ease. There are 6 buttons on this mouse which are all conveniently placed and it feels comfortable even after long time use. Tested and fully compatible with Windows XP, Vista, 7, 8, and 10. And yes, it works on Linux too (tested on Ubuntu).The response time is swift: there is no lagging observed. Overall, an excellent value for money and also great in terms of quality. Goes perfectly with a Tecknet mouse pad. For the more Technical users: This mouse is capable up to a 2400 DPI setting which is perfect for most users, however if you are a pro gamer for instance and need more than that, try one of the gaming mice from Tecknet, you won't be disappointed. I also own a HYPERBOLT which is capable up to 16400 DPI and has 13 Assignable Buttons.

Easily connected, good quality, great value
Color: Purple
This is a well made, quality product. Its fast or slow depending on how you set it up. I have dropped mine at least a dozen times. No not on purpose. I am partially paralyzed and my fingers basically work but they are numb. I tend to drop things. It looks great. The lighting is sufficient. It is gamer friendly. The scrolls easily. It's a great value for the money. It has sleep-mode.
