The catch
Sennheiser HDB 630
A charged, powered headset is still required for the analog cable, and using USB means disconnecting Bluetooth.
Side by side
Sennheiser HDB 630 vs Shure AONIC 50 Gen 2: ANC and the microphone are disabled by Shure Hi-Res USB
Quick verdict
HDB 630 is the one to get if you want its included BTD 700 transmitter and a documented 24-bit/96 kHz USB headset route. Bluetooth must be disconnected for USB, and the headphones need to stay charged even for analog playback. AONIC 50 Gen 2 is the one for selectable Bluetooth source priority and stored EQ, but exit USB Hi-Res Listening before a meeting, because that mode disables its microphone, ANC and EQ.
Before you buy
Why, and what it costs you
In a noisy home office, the highest USB setting can be the wrong one
Say you listen between meetings while someone else works or cooks nearby. In Shure USB Hi-Res Listening, ANC and the microphone are removed, and so is EQ. You would have to leave that mode to get back the call route and the processing you expected. Buy Shure if that deliberate mode change works for you. HDB 630 has a documented USB headset setup but requires Bluetooth disconnection, so neither should be bought as an unrestricted combination of every advertised feature.
Where this comes from
Among the functions Shure lists as disabled in USB Hi-Res Listening are the microphone and ANC. HDB 630 documents USB input and output once Bluetooth is disconnected.
The catch
Shure AONIC 50 Gen 2
ANC, Environment, microphone, EQ and Spatializer are all disabled in USB Hi-Res Listening. Its headline USB resolution does not come with the full work-and-music feature set.

What this page compares
USB modes, the included transmitter and two-device controls, side by side. See where it gets tricky when music, meetings and a noisy shared room all rely on the same headphones.
Each suits a buyer who wants wireless ANC and a serious wired music connection in one pair. Mode restrictions count for more than the largest sample-rate number.

The top Shure USB mode needs to provide ANC and a microphone as well
Shure turns off both in USB Hi-Res Listening. HDB 630 supports a USB headset route, with Bluetooth disconnected.

How we worked this out
Among the functions Shure lists as disabled in USB Hi-Res Listening are the microphone and ANC. HDB 630 documents USB input and output once Bluetooth is disconnected.
A shared desk forces a choice between interruptions and extra hardware
Static multipoint on Shure is useful when a personal phone stays connected but a new media clip should not steal the current laptop audio. HDB 630 offers a different convenience, which is that its transmitter is already in the box for a compatible source. Choose based on the inconvenience you really have. Shure deals with who takes over playback, while HDB 630 can save you buying a separate transmitter. We have not established identical takeover settings on HDB 630.
How we worked this out
Selectable Static and Dynamic multipoint are documented for Shure. Sennheiser includes BTD 700. Equivalent source-priority controls on HDB 630 were not confirmed.
The tuning you prefer may be worth more than the biggest USB number
If you have already tuned the sound for your music, the highest-resolution USB mode on Shure removes that EQ. A listener who wants the same tuning on a commute and for an evening album may choose a supported ordinary mode over 384 kHz. HDB 630 adds crossfeed and parametric adjustment for a different kind of control. These are reasons to audition the settings and not evidence that either product sounds better or corrects a hearing condition.
How we worked this out
Shure bypasses EQ outright in USB Hi-Res Listening, while Sennheiser documents parametric EQ and crossfeed. Having them does not establish which sound you will prefer.
Plug in your setup
Which headphones suit the way you listen?
Start with how you listen. Charging over USB is not the same as playing audio over USB, and some headphones need power even on a cable. These answers are placeholders until you apply your own.

Battery figures are maker claims for the stated mode. They do not reflect measured travel time. Volume, codec, calls and battery age all change runtime. Closed earcups can still leak some sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not judge sound quality, mic quality or amplifier power.

Spec by spec
Where they really differ
| Spec | Sennheiser HDB 630 | Shure AONIC 50 Gen 2 | In practice |
|---|---|---|---|
| USB music and meetings | USB audio supports computer input and output up to 24-bit/96 kHz. The setup procedure requires disconnecting Bluetooth. | Ordinary USB use supports a computer headset microphone. USB Hi-Res Listening disables ANC, Environment, microphone, EQ and Spatializer. | Moving to the highest-resolution mode on Shure changes which everyday functions stay available. |
| Source hardware in the box | The standard US HDB 630 package includes a BTD 700 USB-C transmitter. It stores one headphone profile and needs a compatible USB data source. | SBH50G2-BK is the standard black package with analog and USB cables. A USB wireless adapter is not included. | If your computer or phone needs a wireless transmitter, compare complete setups. |
| A second device starts playing | Two Bluetooth devices can be connected, with one audio source playing at a time. | Static multipoint keeps the current audio source. Dynamic multipoint lets the second connected device take priority. | Shure lets you decide outright whether the second device can take over. That helps on a desk shared with a personal phone. |
| Equalizer use | Parametric EQ and selectable crossfeed are available in Smart Control Plus. | EQ settings are stored on the headphones. USB Hi-Res Listening bypasses EQ, and its supported sample rates exclude 44.1 kHz multiples. | A mode that skips your preferred tuning may count for more than one more supported sample rate. |
| USB power from the source | USB charge-and-play charges HDB 630 during playback. | USB charging is supported and the app includes When to Charge control. | A phone acting as the audio source has a battery of its own to protect. Look at charging behavior before a long trip. |
Trade-offs
What each pick costs you
With Sennheiser HDB 630
- A compatible USB data port is taken up by the transmitter, which keeps one headphone pairing.
With Shure AONIC 50 Gen 2
- No wireless USB adapter comes in the SBH50G2-BK package selected here. Check the third-party Amazon seller and warranty eligibility.
Change of plan
When the answer changes
Your compatible USB source needs a transmitter and you want one in the box
Go with Sennheiser HDB 630. BTD 700 comes with HDB 630 and stores one headphone profile.
Deciding which Bluetooth device gets priority is central to your work routine
Go with Shure AONIC 50 Gen 2. Static and Dynamic multipoint settings are documented for Shure.
You plan on Shure USB Hi-Res Listening and still expect its ANC and microphone
Neither model fits. Those functions are not available in that Shure mode. Decide whether switching modes or using a different connection suits the job.
Decision guide
Before you buy
Music features worth the price shouldn’t cost you the microphone or the quiet a shared work desk requires.
What this page can’t tell you
- We performed no matched testing of ANC, calls, comfort or sound quality.
- Neither manufacturer provides a matched battery test basis that would allow a strict endurance ranking.
- Current primary documents disagree on HDB 630 weight, so it is left out. Passive analog operation on the Shure is still unverified.
