Description

The mid tier, where saving does not pay

The EncorePro 500 sits between the 300 and 700 ranges. Against the 300 it mainly adds build quality: aircraft-grade aluminium joints, a more refined hinge for the earpieces and a wider choice of wearing styles. In a contact centre, where the headset goes from the head to the desk and back twenty times a day, that tells on service life. It is also lighter, 74 g against 105 g on the 320.

Four wearing styles in one range

The 500 is the only one of the three that offers all four wearing styles. The 510 and 515 are monaural, the 520 and 525 stereo, the 530 is worn on the ear and weighs only 22 g, and the 540 and 545 are convertible, that is with a headband and an earloop in one box. This is the main reason the 500 range is deployed where agents pick what suits them.

What a voice tube is and when to want one

The models with the letter V, that is the 510V and 520V, have a voice tube instead of a conventional microphone. It is a hollow tube that carries the voice from the mouth to the microphone. It is clear, easy to clean and replaceable; we carry the spare under code 85Q39AA. It suits operations with hygiene requirements and places where headsets rotate between agents. The drawback is that the tube is more fragile and has to be replaced.

Strengths and limits

Strengths

Aircraft-grade aluminium joints, a longer service life than the 300 range
Four wearing styles in one range, including over the ear and convertible
A weight of only 52 g, exceptionally little among corded contact centre headsets
A QD break-away, the agent leaves the desk without taking the headset off

Limits and what to tell the customer

The headset will not connect to a desk phone. The USB-A connector is meant for a computer, a phone needs the QD version with a cable.
The agent cannot disconnect from the desk with one click, as the QD version allows. They must take the headset off or unplug it from the port.
The box holds the headset alone. No cable, no guide, no spare ear cushions.
Platform certification differs from model to model across the USB codes and some of them also carry the retired Skype for Business platform. Always verify it for the specific code.

⚑ atlantis note

With this code you need not ask about the cable

This is the simpler half of the range. The headset plugs into USB and works, nothing is bought with it. Watch the opposite case though: if the customer needs to connect a desk phone as well, this code cannot do it and the QD version with the matching cable is theirs. So ask whether calls are made from the computer only.

Let the agents choose the wearing style

The 500 is the only range with all four wearing styles and that is worth using. On a larger deployment order a few units of each configuration to try. After eight hours the difference in comfort between wearing on the ear and on a headband is substantial and it varies from person to person. The convertible 540 settles the argument by letting the user choose.

Certifications on the USB codes are not aligned

The universal USB codes in the 500 range have three different certifications: Skype for Business on the 515, Zoom on the 525 and Skype for Business again on the 545. Skype for Business is a long-retired platform. If the customer requires certification, verify it for the specific code and expect HP's entry to be stale. The Microsoft Teams versions, that is 783R1AA and 783R2AA, carry Teams certification and a dedicated button.

Who it suits

Recommended deployment
Recommended use	a smart digital contact centre headset with aircraft-grade aluminium joints, a flexible noise cancelling boom and a choice of QD or USB connection
Position in the portfolio	corded contact centre headsets, EncorePro 500 range, the middle of the three
How it differs from the 300 range	a tougher build with aluminium joints, a lower weight and four wearing styles instead of two, plus voice tube variants

Suitable

Contact centres on shift work where headsets change users daily and have to last. Workplaces where agents pick their wearing style. Operations with hygiene requirements, where a voice tube fits.

Verify

What the headset plugs into and pick the adapter or cable accordingly. Which wearing style the agents want. Whether the customer requires platform certification, which only the USB codes carry. Whether a voice tube is wanted.

Consider another model

EncorePro 300 for a more affordable volume deployment, EncorePro 700 for the top tier, Blackwire 3200 for an ordinary office, Savi 7300 for a wireless contact centre.

The “Verify” and “Consider another model” cards come from the experience of the atlantis team.
