Logitech Pebble Keys 2 K380s vs K585

Choose Pebble Keys 2 K380s for its narrower layout and three paired-device channels, accepting that it has no dedicated numeric keypad. Choose K585 for a number pad and built-in phone holder when two-device switching is enough. Neither choice establishes faster, quieter or more comfortable typing.

The buying question

Do you need a dedicated number pad, and will two prepared host connections be enough?

K380s omits the dedicated numeric keypad and offers three paired-device channels in a narrower body. K585 includes the number pad and a phone holder but switches between two devices.

Quick verdict

Choose Logitech Pebble Keys 2 K380s if

  • You want a compact layout and are comfortable using the top row for numbers.
  • You rotate among three devices and want a prepared channel for each.

When to skip: Skip K380s if the keyboard must have an integrated numeric keypad. Skip K585 if three prepared Easy-Switch host channels are essential.
When the recommendation changes
  • A third regularly used host needs its own prepared keyboard channel.
  • Numeric entry is frequent enough that you want a dedicated keypad.
  • Your bag, desk or phone case does not fit the chosen keyboard and holder arrangement.

The differences that matter

Portable Layout And Number Entry

Logitech Pebble Keys 2 K380s

A compact layout without a dedicated numeric keypad. Numbers remain available on the top row, as shown in the exact product image.[1]

Logitech K585 Slim Multi-Device

A layout with a dedicated number pad and a built-in holder for a suitably fitting phone.[3, 4]

What this changes: Choose K380s when you prefer the smaller layout and are content entering numbers on the top row. Choose K585 when a dedicated number pad is part of your routine. The holder may also help position a phone, but its fit depends on the phone and case.[1, 3, 4]

The better fit depends on your priorities

Saved Host Count

Logitech Pebble Keys 2 K380s

Supports up to three paired devices. After pairing, a short press of an Easy-Switch button selects the prepared channel.[1, 2]

Logitech K585 Slim Multi-Device

Easy-Switch changes typing between two devices, such as a computer and a compatible phone.[3]

What this changes: If you regularly rotate among three hosts and want a prepared channel for each, choose K380s. If two hosts cover your routine, K585 meets that count and the number pad can decide the choice. This is switching the active destination, not typing to all hosts at once.[1, 2, 3]

The better fit depends on your priorities

Best for your routine

Carrying a narrower keyboard without a dedicated number pad

Best fit: Logitech Pebble Keys 2 K380s

Based on listed features, not comparative testing.

K380s has the narrower published width and omits the dedicated keypad. Check the full dimensions against your bag; this is a layout choice, not a durability test.

Frequent entry using a dedicated number pad

Best fit: Logitech K585 Slim Multi-Device

Based on listed features, not comparative testing.

K585 includes the keypad that K380s explicitly omits. That provides a familiar number-entry arrangement without proving faster or more accurate work.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

Choose the layout and channel count you need rather than assuming a higher price buys better typing. If a USB receiver is necessary for K380s, account for its separately sold Bolt receiver; the selected K585 includes a Unifying receiver.

There is not enough price history here to assess purchase timing.

Limitations

  • This comparison covers English US Tonal Graphite K380s 920-011775 and English US Graphite K585 920-011479. Original K380, other regional layouts and different packages are not interchangeable evidence.
  • Neither keyboard was tested hands-on. No typing-speed, comfort, noise, latency, wireless-reliability, battery-endurance or travel-durability winner is established.
  • A phone holder does not guarantee that your phone and case fit. Keyboard body dimensions also do not guarantee clearance for a bag, mouse or desk accessories.
  • Check the current operating-system requirements for the connection you plan to use. Optional customization software has its own supported-platform requirements; a basic keyboard connection does not guarantee every shortcut or software feature.
  • The supporting K585 brochure is dated 2022 and was retained from October 5, 2026. Its exact part and included receiver were checked against the current manufacturer page; no package dimension is used as a keyboard dimension.

Questions shoppers ask

Does K380s have a number pad?

No. Logitech explicitly describes its layout as lacking a dedicated numeric keypad. The top number row remains available. K585 includes a separate number pad.

Can I keep a computer, tablet and phone paired for switching?

K380s supports up to three paired devices, with a short press selecting a prepared channel. K585 documents two-device Easy-Switch. Confirm each device’s operating-system and connection support; switching does not send typing to all devices simultaneously.

Can the K585 receiver also connect K380s?

The selected K585 includes a Unifying receiver. Logitech explicitly says K380s is not compatible with Unifying; its USB receiver option is a separately sold Logi Bolt receiver. Both also offer Bluetooth Low Energy for compatible hosts.

Methodology and sources

Compared the physical number-entry layout separately from the number of prepared host connections, then checked body width and receiver requirements that can affect the purchase.

AI helped organize the manufacturer information and draft this comparison. Neither keyboard was tested hands-on.
