Plantronics Earpiece Replacement & Accessories
Our official earpiece replacement kit restores comfort and acoustic seal for Explorer, Voyager, M165, M25, and M55 Bluetooth headsets. Each kit ships with three eartip sizes (small, medium, large) plus one foam earloop adapter, matching the original factory configuration. We use the same medical-grade silicone found in new headsets—no third-party substitutes—so you maintain certified voice isolation and passive noise reduction.
Designed for professionals who wear headsets four or more hours daily, these earpieces resist oils, sweat, and UV exposure longer than generic alternatives. The tapered nozzle geometry ensures a secure fit inside the ear canal without creating pressure points, and the low-durometer silicone flexes with jaw movement during calls.
- Three graduated eartip sizes: 6 mm, 8 mm, 10 mm diameter for universal fit
- Medical-grade silicone certified for skin contact (ISO 10993-10)
- Compatible with Explorer 50/55/80/110/120/230/240/500 series
- Compatible with Voyager 5200/Legend/Edge/Pro UC models
- Foam earloop stabilizer included for over-ear wearing style
Materials & durability
We manufacture every plantronics earpiece from Shore 40A silicone, the same polymer used in contact microphones and hearing aid domes. This formulation resists lipid degradation—common ear oils won’t cause surface crazing or stiffness after sixty days of wear. Laboratory aging tests show our silicone retains 94% of its original elongation after eighteen months of simulated daily use, compared to 68% retention in commodity eartips.
The nozzle bore is laser-cut to ±0.05 mm tolerance, ensuring the sound tube seats flush against the headset driver housing. Acoustic leakage at this junction reduces treble response and allows ambient noise to bleed into calls; our tight manufacturing tolerance prevents both issues. Tensile strength exceeds 8 MPa, so the earpiece won’t tear when you pull it off the headset post, even after prolonged exposure to perspiration and skin acids.
Sizing & fit guide
Choosing the correct eartip size
Small (6 mm): fits ear canals 5–7 mm in diameter; typically suited for smaller adult ears or youth users. Medium (8 mm): the most common size, covering 7–9 mm canal diameters; ships pre-installed on new headsets. Large (10 mm): for 9–11 mm canals; preferred by users who require maximum passive isolation in noisy environments. If you’re uncertain, start with medium and move up one size if the earpiece feels loose or down one size if you experience pressure after twenty minutes of wear.
Over-ear vs. in-ear wearing
The included foam earloop converts the headset to over-ear style, routing the microphone boom over the top of your ear instead of inserting the eartip into the canal. This configuration distributes weight across the outer ear cartilage and works well for users with narrow or sensitive ear canals. The same replacement parts that maintain long-term seal integrity on the eartips also apply to the ear cushion foam, which shares identical material certifications and cleaning protocols.
Maintenance & replacement intervals
We recommend replacing eartips every three to four months under normal use (two to three hours per day), or every six weeks for extended-wear professionals logging six-plus hours daily. Visual indicators for replacement include visible discoloration, surface tackiness, or loss of elastic rebound when you compress the tip. Clean eartips weekly with lukewarm water and mild dish soap; air-dry completely before reinstalling to prevent moisture accumulation inside the headset sound tube.
Foam earloop adapters degrade faster than silicone tips due to their open-cell structure. Replace foam components every four to six weeks if you wear the headset over-ear style regularly. Never use alcohol-based cleaners or hydrogen peroxide on silicone earpieces—both solvents accelerate polymer crosslinking and cause premature hardening.

Plantronics earpiece replacement questions
Replace your eartip when you notice surface discoloration (yellowing or darkening), loss of flexibility (the tip doesn’t spring back quickly when compressed), visible cracks or tears, or a tacky or sticky texture when dry. These signs indicate polymer degradation that reduces acoustic seal and comfort. For daily users, we recommend proactive replacement every three to four months even if wear isn’t visually obvious, since the seal integrity degrades gradually and affects call quality before you notice physical damage.
This kit fits all Plantronics and Poly Bluetooth headsets manufactured from 2012 onward that use the 2.5 mm sound tube standard, including Explorer 50/80/100/110/120/230/240/500 series, Voyager 5200/Legend/Edge/Pro UC, and M-Series M165/M70/M55/M25 models. Pre-2012 headsets such as Voyager Pro, Discovery 975, and Savor M1100 use a larger 3.0 mm tube diameter and require our legacy replacement kit (PLT-ERTIP-LG), sold separately. Check your headset’s model number or measure the existing eartip nozzle diameter to confirm compatibility.
Yes, our medical-grade silicone eartips are dishwasher-safe on the top rack with no heated dry cycle. Place them in a small mesh bag or silverware basket to prevent them from falling through the rack. Use a mild detergent and avoid rinse aids or sanitizing cycles, which can leave residue. Air-dry completely before reinstalling on your headset. For routine cleaning between dishwasher cycles, lukewarm water with a drop of dish soap and a soft toothbrush work well. Never use alcohol, hydrogen peroxide, or bleach-based cleaners, as these degrade silicone over time.
Small eartips measure 6 mm outer diameter and fit ear canals 5–7 mm wide. Medium eartips measure 8 mm and accommodate 7–9 mm canals; this is the most common size and ships pre-installed on new headsets. Large eartips measure 10 mm and fit 9–11 mm canals, typically preferred by users who need maximum passive noise isolation. The correct size should form a gentle seal without pressure or discomfort after twenty minutes of wear. If the eartip feels loose or ambient noise bleeds into calls, move up one size; if you feel pressure or soreness, move down one size.
Yes, all components in our official replacement kit carry a two-year material integrity warranty from the date of purchase. The warranty covers manufacturing defects including premature cracking, discoloration, or loss of elasticity under normal use. It does not cover damage from improper cleaning (use of harsh solvents), physical abuse, or wear beyond the recommended replacement interval. To file a warranty claim, contact our support team with your order number and photos of the defective component.
The included foam earloop adapter is compatible with all Plantronics Bluetooth mono headsets that have a curved microphone boom, including Explorer and Voyager models. It slides over the boom to convert the headset to over-ear wearing style, distributing weight across the outer ear cartilage instead of relying solely on the in-ear eartip. The adapter does not fit stereo headsets (Voyager Focus, BackBeat) or models with fixed boom geometry. M-Series headsets (M165, M70, M55) use a different earloop design and require model-specific loops, sold separately.
Replace foam earloop adapters every four to six weeks if you wear your headset in over-ear configuration regularly. Foam degrades faster than silicone due to its open-cell structure, which absorbs oils and perspiration. Signs that replacement is needed include visible compression set (the foam no longer rebounds to its original thickness), surface pilling or flaking, or loss of grip on the headset boom. Clean foam loops weekly with mild soap and water, then air-dry completely; avoid wringing or twisting, which tears the cell structure.
