DON’T CANCEL THESE FROM YOUR SHORTLIST

[This review was collected as part of a promotion.] BACKGROUND Testing was carried out at home whilst connected via the provided cable and wireless Bluetooth connection. I used sound from my Sony hi-fi, TV, phone and other Android pads and personal computers. Various music was tried out, ranging from rock and pop to classical. I am retired, living in Bedford, UK and own a number of Sony products including a Sony A/V setup comprising TV, A/V receiver, UHD player, maxi hi-fi and phone. I also use Sony ear buds when out walking, connected to my mobile. I have various headphones to compare with. LEARNING HOW THEY WORK Inside the box lid there is a 1-2-3 diagram to get you started. 1 has a Q code to the Help Guide which is clear/simple to follow, getting you working quickly. 2 and 3 on the box show what to do if you cannot read the Q code - switching them on and listening. This is of little use - access to the Help Guide is critical but needs an Internet connection. The Reference Guide is in small type, users may struggle with that, and covers safety, Bluetooth connection and charging. CHARGING THE HEADSET/BATTERY LIFE The time to charge is 3-3½ hours using a USB AC adaptor (>500 mA) and a full charge should last at least 28 – 50 hours of use, longer if inactive (Sony Guide). You can also use a PC USB outlet but the charge time may be longer. Always use a USB-C cable and disconnect once completed. A short charge (10 mins) will give you around 3hrs use. The charging LED is orange whilst charging and goes off when complete. FEATURES Left Enclosure • Noise cancelling microphone – when used • Bluetooth antenna (built in) • Tactile dot for identification (half way down rear side) and ‘L’ inside enclosure • Indicator Light – Blue for Bluetooth connection, orange if charging • Power button – Hold down for 2-3 seconds until the light flashes blue • USB-C connector for charging • Call microphone – for voice • 3.5mm Headphone cable input jack socket for wired connection (push until it clicks) The indicator light has a number of other uses to show their status. These are for charging, Bluetooth and receiving calls. Right Enclosure • ‘R’ inside enclosure • Noise cancelling microphone – when used • ‘+’ and ‘-‘ buttons - control volume, either side of Play/Next/Previous button • Play/Call/Next/Previous button – Raised bar on button – Controls playback on Bluetooth device • NC/AMB – Noise Cancelling/Ambient Sound Music button to switch options • Serial number inside the unit WEARING THE HEADSET Check the left/right units of the headset. There's a tactile dot on the left unit half way down the rear side near the hinge of the enclosure. • Extend the slider as far as you need, before putting on the headset • Put on the headset with the earpads snugly covering your ears • Adjust the length of the slider so the headband touches the top of your head • Adjust the position of the enclosures so that they fit snugly around your ears CONNECTIONS USING BLUETOOTH Connections can be made to many Bluetooth items, e.g. phones, pads, PCs, hi-fi, etc. Start by turning on the headset, the indicator will flash blue ready for pairing. Continue using the procedures applicable to the source. The headset will show as ‘WH-CH730N series’ Once connected, the headset will try to connect automatically with the last used source next time. To enter pairing mode manually you just need to hold the power button 5 seconds or more. WIRED CONNECTIONS When you use the supplied cable to connect the headset you lose the Bluetooth functions on the right enclosure (Volume and play/ability to adjust the headset buttons it is still possible to use the supplied cable to plug into headphone jack sockets on other appliances. The angled end of the cable should be plugged into the sound source and the straight end into the headset. Note you don’t need to turn the headset on with a wired connection but the noise cancelling only works if it is on. SOUND CONNECT APP Sony have provided this app which enables access to: • Battery status • NC/AMB button control – Control and setting switch pattern • Adaptive Sound Control – Automatic setting by actions • Listening Mode – Settings can be adjusted based on content or usage • 10 band Equalizer – Use presets to adjust sound, e.g. Heavy, Soft and two custom settings • DSEE – Upscale audio to CD quality • Max Volume Control – Set personal limit • 360 Reality Audio – Set the feature up • Bluetooth Connection Quality – Prioritize sound quality or signal stability • Quick Access services – Create short cuts for services • Voice Assistant – Set the voice assistant (AI – e.g. Google Gemini) you wish to use • Battery Care – Helps to extend battery lifespan – very useful • Automatic Power Off – Set delay before this operates • Software Version – Display • Update the Software – Set how/when to update • Listening History – Review your activity • Help – Support information for the headset This is an excellent app and should be downloaded as the features and information available enhances the headset experience no end. BUT HOW WELL DOES IT WORK… Connecting to my Sony phone and Android pads was simple and gave me a good, well balanced sound without any adjustments being required. Connecting to my Windows 11 PC was not successful, but the Bluetooth version may be too old to connect. WIRELESS CONNECTION With the headset connected to my Sony and Samsung mobile phones and various Android pads the sound quality was excellent at all times, hardly needing any adjustment. Using the 10 band equalizer enhanced the sound for particular genres, e.g. bass for rock music. When it came to hi-fi, Bravia TV and my PC the headphones made the connection but the volume was too low to be usable and I was unable to change it despite restoring the headset to factory presets to clear the previous pairings. WIRED CONNECTION The supplied lead opened the use of my PC, my A/V amplifier and older hi-fi units. Again the quality shone through, using the headset as reference speakers whilst searching for suitable music for a home video. The cable at 1.2m is long enough for most listening but is easily extended with the right lead.   MOBILE CALLS Once connected to a smartphone you can make calls. Call the number you wish and the sound will be heard in the headset. Volume controls can be used and to end the call just press the call button between the volume controls. The sound is clear and the headset picks up your voice when you speak. Note that the phone needs to be 50cm away from the headset to avoid extra noise. If your phone supports Hands-free profile you can press the call button (between volume buttons) to start the voice dial function via Gemini on an Android phone or Siri on the iPhone. With incoming calls: • Press the call button once to answer. • Press and hold the call button for a few seconds to reject. (Not available with Headset Profile) With outgoing calls: • Press the call button once to cancel. During a call: • Press the call button once to finish a call Voice support for video calls may also be available depending on the app used. COMFORT At all times I found the headset comfortable and the pressure on the sides was strong enough to close all but the loudest sounds out yet easily wearable for hours. It is easily adjustable through sliders in the head band and being light (203g) makes them sit nicely on your head without any downward pressure. My wife enjoys the low level of sound from the headset and also likes the NR system. The soft covers around the ears are very good at reducing external noise and are replaceable but I didn’t remove them to check the ease of this. WATER RESISTANCE The headset is not waterproof. If water or foreign matter enters the headset, this can result in burnout or malfunction, so be careful. VALUE Sony appear to have pitched the price of this headset in the mid-range and what you get for your money is well worth the cost. The number of features included justifies the price and the NR system fares well in its class.

could do a little better

No complaints with the headphones but no charging cable and no instructions any where to be seen!

Lightweight & Functional.

[This review was collected as part of a promotion.] As an owner of Sony cordless noise cancelling headphones in dire need of replacement, I wanted something that provided me with similar functionality to my existing headphones, but something more lightweight. These did the trick perfectly. Lightweight, although quite tight around the head, there is no compromise on sound quality, with a hefty bass and decent battery life. Recommended.

not worth it

plastic felt very cheap and the sound cancelling was non existent, returned straight away 🤷‍♀️

Excellent lightweight headphones.

[This review was collected as part of a promotion.] On opening the packaging of the headphones, it was apparent that great thought has gone into the recyclable materials. The headphones themselves, felt very lightweight and I thought that the quality may not be the best. I am glad to say that I was very much mistaken. Being a bald person (by choice) I do not have any hair to cushion the headband. But they were so comfortable, it was a pleasure to wear them. After charging and connecting them, which was very easy, I decided to give them a test run. Walking alongside a busy road, the noise cancelling worked really well. Even with it on ambient noise, the quality of the music was great. It was a windy day, with the noise cancelling on, you had no interference in the sound quality. The next test was on a rather busy, and long train journey (yes, usual delays). Again the noise cancelling was really good, and with it off, you could hear the announcements. Making or receiving a call was simple, and the call quality was very good. After doing the walk and return train journeys, there is still plenty of battery life, so no need to worry about constantly having to charge them. The sound connect app. lets you adjust the equaliser to suit your listening preferences. Overall, an excellent, lightweight pair of headphones with great features and sound quality.

I can’t hear the wife when I’m wearing them :)

I got these at an incredible price on offer through my internet provider so I can’t begin to complain about anything. They run out of black so I was offered beige. At 75% off I didn’t mind. I still have to wire them up for some of my gadgets unless I buy a Bluetooth transmitter but great for use with my iPhone and Firesticks….Late night gaming and guitar playing is a breeze.. they are light and comfortable …

Poor call quality

Poor sound quality during phone calls with and without wind

Very good headphones - that's my honest opinion!

I recently bought these headphones having disposed of a pair that disappointed me from another well-known brand. These Sony headphones are far, far better particularly in comfort and battery life. Sound qualkity is excellent - I don't play bass-heavy dance tracks (too old!) but no complaints with the overall sound quality for the music to which I listen. The noise-cancelling function is excellent - I often sit with them on, without music playing, to isolate myself from some TV programmes my wife is watching. So, a great product from Sony.
