These are premium wireless headphones; they are over-ear but relatively compact and lightweight (285g). They are an upgrade of the previous model, Beoplay H9, with longer battery life (35 hours), upgraded ANC (Active Noise Cancellation), and four microphones in place of two. It is not top of the B&O range; for that you need to spend quite a bit more for the H95. Gamers are directed to the similarly-priced Portal model which has a few more features (Dolby Atmos, Xbox Wireless) but shorter battery life and no case; worth considering as it probably sounds equally good but I do not have a Portal to compare.

In other words, if you are a hi-fi enthusiast, the HX will remind you of why. I could also easily hear the difference between the same tracks on Spotify, and CD or high-res tracks on my Sony player. AptX HD is supported.

Luckily there are some real buttons on the HX. These cover on/off, and ANC control, which toggles between on, transparent (hear external sounds) and inactive. There is also a multi-button which activates voice assistants if you use these.

There is a 3.5mm jack connection for wired use, but with two important limitations. First, this does not work at all if the battery is flat; the headphones must be turned on. Second, the jack connection lacks the extra connection that enables use for calling, so for listening only. The sound quality was no better wired, perhaps slightly worse, so of limited value.

Despite a few annoyances I really like these headphones. I doubt I will use the app, other than for firmware updates, and rarely bother with the touch controls, which means I can enjoy the lovely sound, elegant design, good noise cancelling, and comfortable wear.

How good? It was some years back that Shure opened my eyes (or ears) to how good in-ear monitors (IEMs) could sound. It was at a show, only a demo, and the IEMs had a four-figure price, but it made me realise the potential of in-ear electronics to sound better than any headphones I have heard.

That said, the Aonic 215 true wireless has had a chequered history. Launched in April 2020, they were actually recalled by Shure because of problems with one earphone not playing, or battery issues. Shure fixed the issues to the extent of resuming supply but they are still a little troublesome.

This package of course has them in one. You get a charging case too, which will charge the IEMs three times when fully charged. Play time is up to 8 hours (7 hours probably more realistic). Long enough for me.

Task number one is selecting the right ear sleeve. The aims is to create a seal in your ear. 6 pairs are supplied, including the one pre-attached. The best in my opinion are the foam type which form themselves to the shape of your ear, and which come in small, medium and large. Changing these is a little awkward and as ever one worries about damaging the unit but with a little twisting and tugging it is not too bad. Most other earbuds do not have these foam-type sleeves.

Not for everyone then; but these suit me well. One last thing to mention: Shure unfortunately has a reputation as not the most reliable of earbud brands. In my case, one wireless unit went dead after a couple of weeks. Shure replaced it and all is well, but it is somewhat concerning.

I love technology that endures and one of my most treasured gadgets is a pair of Sennheiser HD600 headphones. Mine are not quite that old, but this is a model that was first released in 1997 and remains on sale; they sound fantastic especially with a high quality headphone amplifier, and I use them as a kind of reference for other headphones. The ear cushions and headband perished on mine and I bought the official spares at an unreasonable price because I so much wanted to keep them going.

Passive headphones like my HD600s are in decline. I call them passive because they have no built-in electronics other than the speaker drivers. They can only work when wired to the output from an amplifier. Wires can be a nuisance; and as wireless options become cheaper, better and more abundant, wired is in decline (though it will never go away completely).

Once you go wireless, something else happens. The signal the headset receives over Bluetooth or wi-fi is a digital one. Packed into the receiving electronics is not just a pair of speaker drivers, but also a DAC (Digital to Audio Converter) and an amplifier. Further, the amplifier can be optimized for the drivers. The output can be equalized to compensate for any deficiencies in the drivers or the acoustics formed by their case and fit. This is an active configuration and has obvious advantages, getting the best possible performance from the driver and also enabling smart features like active noise cancellation (if you add microphones into the mix). It should not be surprising that the better wireless devices sound very good. I have also noticed that headsets which offer both wired and wireless modes often sound better wireless, despite the theoretical advantages of a wired connection.

Another significant development is that off-the-shelf chipsets for wireless audio have got better. The leader in this is Qualcomm whose Bluetooth audio chipsets are packed with advanced features. SoCs like the QCC 3506 include adaptive active noise cancellation, 24-bit 96Khz audio, low power consumption, voice assistant support, fast pairing, built in DSP (Digital Signal Processing), and of course programmability for custom features.

A few years ago I attended a press event at CES in Las Vegas. Shure was exhibiting there and I got to try a pair of its premium IEMs (In-ear monitors). Until then I had been convinced that earbuds could never be as good as headphones; but what I heard that day changed my mind. The audio amazed me, sounding full, rich, spacious, detailed and realistic. I thought for a moment about it and realised I should not be surprised. IEMs are designed to be fitted directly to your ears; why should they not be of the highest quality? The best ones, like those at CES, have multiple drivers.

There is something else though. Getting the best sound from IEMs requires getting an excellent fit since they are generally designed to sealed into your ears; the once with expandable foam ear seals are perhaps the best for achieving this. If they are badly fitted then you will hear sound that is tinny or bass-light.

This means that it is worth taking extreme care with the selection of the right ear seals or ear sleeves, as they are sometimes called. Most earbuds come with a few sizes to accommodate different ear sizes. If the sound changes dramatically when you press the earbuds in slightly, they are not fitted right.

Something else regarding Shure, that I did not realise until recently, is that all its earbuds are designed to have a cable or (in the case of the wireless range) clip that fits behind your ears. The reason for this is that it makes it easier to get a good fit when the cable is not constantly pulling the IEMs out of position. Check out this video for details.

It is a common problem. You fit your earbuds and then go for a run or to the gym. With all that movement, one or both of the earbuds falls out. This can be a serious problem with wireless models. If you lose your earbud in the long grass or on a busy street; you might never find it again, or someone might trample on it.

This is the wireless version of an older model, also called Stir it up. The name references a Bob Marley song, and yes there is a family connection. Marley manufactures a range of relatively inexpensive audio products with a distinctive emphasis on natural and recycled materials.

The turntable is no exception, and has an attractive bamboo plinth and a fabric cover in place of the usual Perspex (or similar) lid. The fabric cover is actually a bit annoying, since you cannot use it when a record is playing (it would flop all over it).

I am familiar with turntable setup, and otherwise would have found the setup instructions confusing. The belt is a suppled already fitted to the platter. You have to poke it round the drive pulley through a hole in the platter. That is not too hard, but there also conflicting and unclear instructions about how to set the tracking weight and bias correction. What you should do is to ignore the printed instructions and check out the video here. This explains that you fit the counterweight to the arm, adjust it until the cartridge floats just above the platter, then twist the weight gauge to zero, then twist the counterweight to 2.5g, the correct tracking force for the supplied Audio Technical 3600L cartridge. Then set the anti-skate to the same value as the tracking weight.

Connections on this turntable are flexible. You can switch the phono pre-amp on or off; if ON you do not need a phono input on your amplifier, just line in. Alternatively you can plug in headphones, or connect Bluetooth speakers, using the volume control at front right.

Playing record is a matter of placing the record on the platter, setting the speed as required, unclipping the arm, pulling the arm lowering lever FORWARD to lift it, moving the arm over the record (which starts the platter rotating), then pushing the lever BACK to lower it (I found the lever worked the opposite way to what I expected).

All worked well though, and I was soon playing records. First impressions were good. I found the sound quality decent enough to be enjoyable and put on a few favourites. My question had been: can a cheapish turntable deliver good enough sound to make playing records fun? The answer, I felt, was yes.

This was despite some obvious weaknesses in the turntable. The arm does not move as freely as a top quality arm, and the fact that it operates a switch is sub-optimal; it is better to have a separate switch to turn the platter rotation on and off. I also noticed mechanical noise from the turntable, not enough to be spoil the music, but a bad sign. The cartridge is from a great manufacturer, but is about the cheapest in the range. Finally, the platter is lightweight, which is bad for speed stability.
