If you want a wired, compact in-ear monitor for focused listening and video calls, choose Sennheiser Professional IE 100; if you need a wireless over-ear gaming headset with a boom mic and long battery life, choose Sony INZONE H5. For calls at a desk, the Sony’s bidirectional microphone and wireless connection are compelling; the Sennheiser is the simpler fit for anyone who prefers a cable and an in-ear design.
Sennheiser Professional IE 100 vs Sony INZONE H5 at a Glance
• Sony’s biggest strength: wireless gaming, a bidirectional boom microphone, and up to 28 hours of battery life; its trade-off is a larger over-ear design that needs charging for wireless use.
• Sennheiser suits: listeners who want an in-ear monitor for music, wired calls, or use with a 3.5 mm jack.
• Sony suits: gamers and remote workers who want wireless freedom, an over-ear fit, and a dedicated microphone.
• The quick call: choose based on whether you value a compact wired monitor or a full gaming headset with wireless features.
The IE 100 PRO is a wired in-ear monitor built around a dynamic 10 mm driver. Its stated frequency range is 20 Hz to 18 kHz, and its 115 dB sensitivity gives it a clearly specified audio profile. Those figures describe the product, but they do not make it a gaming headset: its focus is in-ear monitoring, with a 3.5 mm connection and a wired remote.
The compact, single-driver construction gives the earpieces a slim shape, while the included silicone and foam tips provide options for finding a secure fit. The optimized earpiece and tips are designed to shield outside sound passively. That can be useful when you want a more contained listening experience, but it is not active noise cancellation. The cable has an internal duct and is described as stage-proof, a practical choice for someone who wants a physical connection rather than a battery-dependent one.
For a headphone for video calls, the IE 100 can make sense if your device accepts its 3.5 mm plug and you are comfortable with a wired in-ear setup. The supplied details do not specify a microphone, so I would not choose it when a dedicated headset mic is essential. Its carrying case, cleaning tool, and foam and silicone adapters make it a more complete in-ear package, but it remains a monitor rather than an over-ear gaming headset.

Who should skip it: Skip the IE 100 if you need wireless listening, a stated battery life, or a dedicated boom microphone for calls.
The INZONE H5 is an over-ear gaming headset with 40 mm dynamic drivers, a 2.4 GHz wireless USB transceiver, and a 3.5 mm audio option. Sony lists a battery life of up to 28 hours and a charging time of 3.5 hours. For someone moving between gaming, calls, and other desk work, that combination offers a practical choice: use wireless when freedom from a cable matters, or connect by wire when preferred.
Its bidirectional boom microphone is a more direct fit for conversations than the IE 100’s listed features. The headset also includes AI-based noise reduction for the microphone, according to its product information. That is a microphone feature, not a claim that the headphones cancel surrounding noise for the wearer. The listed noise control is active noise cancellation, but the supplied details do not explain how it operates in different environments, so I would avoid assuming it replaces a quiet room or careful mic placement.
The over-ear design, nylon earpads, gentle side pressure, and cushioned headband are intended to support longer sessions. Sony lists the weight at approximately 260 g. The headset also supports personalized 360 spatial sound for gaming and sound adjustment through INZONE Hub on PC. Those features are aimed at gaming use rather than making it a dedicated work-call headset, but the boom mic and wireless connection give it more call-specific hardware than the Sennheiser.
Who should skip it: Skip the H5 if you want a small in-ear monitor, do not want to charge a headset, or prefer a simpler wired-only setup.
• Best for a dedicated boom mic for video calls → Sony INZONE H5. It has a bidirectional boom microphone and AI-based microphone noise reduction; the Sennheiser’s listed features do not specify a microphone.
• Best for wireless gaming and calls → Sony INZONE H5. Its 2.4 GHz USB transceiver gives it a wireless connection, with a 3.5 mm cable as an alternative.
• Best for a compact in-ear fit → Sennheiser Professional IE 100. Its single-driver earpieces are designed to be slim and ergonomic, unlike the Sony’s over-ear headset.
• Best for a battery-free wired listening setup → Sennheiser Professional IE 100. It connects by cable and does not rely on a battery for the wired connection.
• Best for longer gaming sessions without a cable → Sony INZONE H5. Its listed battery life is up to 28 hours, though wireless use means keeping it charged.
• Best for passive sound shielding from the earpiece and tips → Sennheiser Professional IE 100. Its optimized fit and silicone or foam tips are intended to provide passive isolation.
• Best for gaming-focused spatial audio features → Sony INZONE H5. It offers personalized 360 spatial sound and PC sound settings through INZONE Hub.
• Best for using a standard 3.5 mm connection → Both. The Sennheiser is wired with a 3.5 mm jack; the Sony can also be used with a 3.5 mm audio cable.
Buying Considerations
Then consider whether you want a headset on your ears or in them. The Sennheiser’s silicone and foam tips allow for a personal in-ear fit and help create passive shielding. The Sony’s cushioned over-ear design is intended for extended gaming sessions, but it is a different kind of physical experience. Neither style is automatically more comfortable for everyone; the better match depends on your preference for in-ear tips versus padded earcups.
Wireless convenience also has a cost in routine. The H5 can run wirelessly for up to 28 hours and takes 3.5 hours to charge, according to its specifications. The IE 100 avoids charging by using a cable, but that cable limits movement. If your desk setup stays in one place, a wire may be no problem. If you move around while listening or want to avoid a cable across your workspace, wireless is the clearer advantage.
Finally, separate gaming features from call essentials. The Sony’s spatial sound and INZONE Hub adjustments may matter if you play on PC or PS5 and want gaming-oriented controls. The Sennheiser is positioned as an in-ear monitor, with a dynamic driver and passive isolation. For wireless wireless headphones for video calls, the H5 is the more relevant design of these two; for a wired, compact listening option where a dedicated mic is not a requirement, the IE 100 remains a reasonable alternative. Check the current price on Amazon if price is part of your decision.
I would choose the Sony INZONE H5 for video calls because it has a dedicated boom microphone, wireless USB connection, and a wired fallback. Its up-to-28-hour battery life also makes it a more flexible gaming-and-call headset, provided I am willing to recharge it. The Sennheiser Professional IE 100 is the better fit for someone who specifically wants a slim wired in-ear monitor with passive shielding. For my call-focused use, I would buy the Sony.
