Sennheiser PX 210 BT Headphones Review | Trusted Reviews

Sennheiser is no stranger to making quality wireless audio products, as evidenced by the RS 170 headphones. The PX 210 BT headphones bring that target of great-sounding, wireless audio to a more portable form factor, exchanging Kleer 2.4GHz wireless technology for the more ubiquitous Bluetooth in the process. Sennheiser’s engineers aren’t daft, though. They know that the sub-band coding used by standard Bluetooth stereo headsets doesn’t provide amazing audio quality. To counter this, the PX 210 BT use the apt-X codec – as also featured by the Creative ZiiSound D5 to great effect. Experience suggests, therefore, that the Bluetooth transceiver won’t be a hindrance to these headphones performance. You’d certainly hope not, bearing in mind the £112 asking price.

And actually that’s not the only cost to consider. If you want to get the best out of the PX 210 BTs, you’ll need a transmitter able to broadcast using apt-X. We were supplied with a Sennheiser BT300i adaptor, which paired automatically, but no doubt third party alternatives will become available in due course. Obviously any device not supporting apt-X can still connect. The design is cleverly portable, with the earcups twisting 90 degrees inwards, and then folding inside the headband, on hinges. A carrying case is provides in the box, so you don’t have to just chuck the PX 210 BTs in a bag unprotected.

There’s enough adjustability in the headband that even those with particularly small or large heads shouldn’t have any problem getting a good fit. Both the headband and earcups are nicely padded, which helps make the PX 210 BTs comfortable to wear even for long periods. It’s possible that the supra-aural design (where the headphones sit on the ear) won’t suit some folks, but we had no complaints. Usefully, and unlike some Bluetooth headsets, the PX 210 BT headphones also feature a headphone jack. Annoyingly this is of the 2.5mm variety, but a 2.5mm to 3.5mm cable is supplied, but it’s great to be able to carry on listening to music if the battery conks out half way through a train journey.

The PX 210 BT headphones are charged over a micro-USB cable, the port for which is hidden under a small flap on the left earcup. Sennheiser quotes 12 hours of battery life, we managed to get about 10. The discrepancy is likely a result of our having to keep them at full volume the whole time when using an iPod. Even then they weren’t particularly loud – at least our hearing is safe though. The right earcup has controls on its outside. The track forwards/backwards and play/pause buttons will work with any AVRCP-compatible player with which headphones are paired, while the volume buttons control the PX 210 BTs directly. This is worth noting as with our iPod touch we had to adjust both volumes to get decently audible sound.

What’s good to note is that there’s a tangible difference between using standard A2DP Bluetooth and apt-X. Indeed switching between Bluetooth with apt-X and the provided cable, there wasn’t any noticeable difference in quality, suggesting that the codec is doing its job properly. The audio quality isn’t what we’d call stellar, but it’s still pretty good. There’s good clarity, with vocals coming across well and a nice warm base, but the high end is a bit lacking in definition for our tastes. Without using an apt-X adaptor the results are less good, with noticeable compression on some tracks, but it’s still listenable. Inevitably a similarly priced pair of non-Bluetooth headphones won’t struggle to best the PX 210 BTs. But, and the ‘but’ is important, once you get used to listening to your headphones, unimpeded by cables you really won’t want to go back to a pair of tethered cans – especially now the use of Bluetooth doesn’t necessarily mean degraded audio quality.


There’s something a little incongruous about bluetooth headsets that actually sound good, but the px 210 bt wireless earbuds deliver. however, you’ll need to factor in the cost of an apt-x adapter in addition to the headset to get the most out of them.
