how to install Poly SHS1890-25/DH Headset Amplifier

  • Prepare and position: Place the amplifier on your desk near your workstation and within easy reach of your headset and computer or phone system. Ensure the environment is stable to avoid accidental knocks during calls.
  • Connect your headset: Insert the headset plug into the amplifier’s headset jack, following the connector type that matches your headset. Confirm a secure fit so audio passes cleanly through the device.
  • Connect to your audio source: Connect the amplifier to the device you use for communication, such as a desk phone, computer, or UC-enabled device, using the appropriate cable or interface per your setup. Ensure that the chosen input/output path aligns with your workflow.
  • Power and test: If the amplifier requires power, connect it to a powered USB port or power supply as specified by the manufacturer. Power on, then place a test call to verify microphone pickup, speaker output, and overall clarity.
  • Adjust for comfort and control: Use the dedicated volume control to set comfortable listening levels and the mute switch to manage on-call interruptions. If you notice symmetry issues between input and output, adjust the gain and test again to achieve balanced audio for both parties.
  • Optimize for UC platforms: For optimal results, check your UC or telephony platform’s audio settings to ensure the amplifier is selected as the active headset device. Run a quick test call and verify microphone pickup and speaker playback across typical scenarios (headset-only, speakerphone, and mixed environments).

Quality and security-oriented wallet
Color: Adventure Brown - Forest Brown
This is a neatly constructed wallet. The material of the leather feels satisfying to carry unlike previous wallets. This wallet consists of many card slots, and allows ease of access between them. The wallet can fit checks, cash and is just a nice layout and style to be able to look through it. Because some of our cards support RFID and NFC technology, bad actors can try to steal our credentials. This wallet has a material to mitigate these occurrences, but like anything in security whether it be physical security controls or the wide scope of cybersecurity, do not rely on it and try to be up-to-date with the trend. I am sure we would all want to be one step above in relation to keeping our credentials secure. Still, it is an excellently built wallet and I highly recommend it.

Beautiful Wallet
Color: With NO Logo - Smooth Nappa Black
Well constructed and beautiful wallet. The black Nappa leather I ordered is soft and smooth to the touch and you can tell by the look, feel, and smell that it is high quality. I love that you can order this with both a logo and no logo for a clean look. The design on this is well thought out. I'd definitely recommend this wallet to anyone. It is an amazing value and far superior to any other $30 wallet I've ever seen.

Almost perfect!
Color: With Coin Pocket - Forest Brown
I purchased this wallet primarily for its generous number of conveniently located slots and its coin pocket. If you can't fit everything you want to EDC in this wallet, you need to think about getting a sling bag! Having returned the same model in Grizzily Brown due to a stitching defect and ordered this one in Forest Brown, I can see it is a richer, lighter shade and the finish seems smoother and more refined. Some of my cards were tight in previous wallet slots, but everything fits great in this one. Why the one star off? First, this wallet is about a quarter inch too large in all dimensions, especially thickness. While it doesn't protrude out the top of my back pocket, it is a challenge to close the button on some pants and it is also snug side-to-side, so removal involves some wiggling until pockets stretch and the wallet breaks in. The leather used in its construction is smooth but stiff at first, given that it is about twice as thick as most American or European wallet leather I've owned: think bullhide. The smell is also a little off, definitely natural cowhide but processed with whatever is used to tan leather in India rather than in the United States. Finally, this looks like something that belongs in a pair of jeans or casual pants, NOT pulled out of a suit at a Michelin star restaurant. The stitching, evenness of dye and lines are far from perfect, but what it lacks in looks it more than makes up for in every day function, character, and anticipated durability.

The Best Wallet
Color: Boulder Black - Napa Smooth Black
This is the second wallet I have purchased from Bull Guard. The first one is identical and I have used it for approximately one year. The first wallet has held up perfectly. I just decided to buy a second one because I am so happy with the first one and I decided to break up my cards into frequently used in the second, new wallet and less frequently used in the first and older wallet. The capacity of the wallet is excellent. It easily holds all my credit cards, drivers license, bills, insurance ID cards, and my global entry card. The material, workmanship, durability, and quality is also excellent. The wallet is all leather and breaks in perfectly. The size is also perfect fitting perfectly in my rear pocket. For the price, this is the best man's wallet I have ever had and I highly recommend it.
