Review: Nokia BH-601 bluetooth stereo headset

This will be the last in my current batch of stereo bluetooth headset reviews, the Nokia BH601. I’ve run out of headsets to review, unless of course one of the manufactuers wants to send me one to play with. Today I’d like to consider Nokia’s next iteration of the the series which previously gave us the flawed BH-501.

Nokia BH-601

Fortunately Nokia have managed to fix nearly all of the BH-501′s flaws – the 601 is a substantially better product in almost every way. Unfortunately Nokia have introduced a range of new problems, which I am sure they will get round to fixing in a year or so.

The first major improvement is that it’s tougher. Nokia have eliminated both of the weak-spots in the bendy plastic adjacent to the earphones. The curves around the earphones of the BH-601 are sturdy bars of flexible plastic with shock-absorbing rubber inserts. They have the appearance of being able to withstand a great deal of twisting and bending. That’s good news because I have a feeling that I will get more than a few weeks use out of this device.

The next major improvement is obvious – they’ve added a few more buttons. Not quite as many as Jabra with their confusing  BT620s, but enough to allow some nifty new features. In addition to the original volume controls and select/power button we now have a track-skip controller.

Oddly enough the volume controls work in a different way to those on the BH-501. They do not seem to be linked into the phone’s volume control. The two act independently rather than (as with the BH-501) change a single volume setting.

Another neat feature is that for the first time Nokia have noticed that nobody likes to be lit up like fairy-lights. This device has two LEDs adjacent to the standard Nokia charging port. The blue light blinks to show that the headset is active and the green light blinks when the headset is on charge. There are no lights visible from the side or front. That’s good news for people who do not wish to be the focus of attention.

It never occurred to me to complain that the BH-501 could not operate while charging. It just seemed like too small a thing to mention, but that’s another thing that Nokia have changed. I’m not sure that I’d ever want to talk while charging as having a charging wire plugged into a headset somewhat negates the benefit of a wireless device. It’s nice they thought of it though, I can confirm that it works.

And now the bad points: The reception range of the BH-601 seems to be considerably worse than the BH-501 (which was excellent). In ideal circumstances the BH-601 will give me 10 metres of range from my Nokia 95 while listening to stereo audio. In an environment with moderate to low levels of radio interference (e.g. a normal city street) the signal will often break down unless I hold the N95 almost adjacent to the headset. I guess the thicker plastic used to make this device absorbs a lot more of the signals.

Speaking of range, a related issue is the device’s ability to recover from an interrupted signal. Unfortunately it’s not good. As I wandered around my office building today, I noticed that somebody operating a photocopier nearby was enough to interrupt the signal. Also the motor which opens the steel gate of the cycle-park put out enough EMF to completely cut the connection.

While a brief interruption may be acceptable in the face of interference, the problem with this device is that once it looses a connection the the link stays lost. The only way to re-connect is to power-down the headset, and then re-boot it. The phone appears not to have detected the fact that the link has failed resulting in complete silence.
Another oddity is that this stereo headset seems to switch to monaural mode every time a call comes in. A phone call is always in mono but one of the advantages of having a headset with 2 earphones is that you can hear the mono audio with two ears at once. When you use the BT-601 to talk on the phone only the left can produces sound. The right can (which includes the microphone) remains silent.

It’s also worth noting that the look and styling of this product seems quite cheap. It’s a better design than the BH-501 but the quality of the plastic molding is poor, and the silvery insert in either of the phones looks very cheap. That’s sad because I would have been willing to pay slightly more for a device that has a more elegant design.

On the whole the BH-601 is a modest improvement on the ill fated BH-501. It’s definitely the best Nokia stereo headset I’ve tried but they still have a long way to go before they deliver the headset I really deserve.

Review: Jabra BT620s bluetooth stereo headset

All I want is a lightweight, robust stereo headset. After yesterday’s disappointing encounter with the Nokia BH-501, we should turn our attention to the Jabra BT620, a device which is the polar opposite of Nokia’s flawed product, but fails to fulfill my ideal criteria for precisely the opposite reasons.

There are many things to like about this solidly built headset. Number one on my list has to be that it does a very good job of what most people will want, the ability to make and receive telephone calls. These come in very clearly and there were no complaints about the audio levels for both speaking and listening. The range and clarity when used as a telephone headset was acceptable.

When taken off the ears this headset is strong enough to be worn around the neck with no signs of damage. Mine is three weeks old now and I cannot see any cracks or signs of wear, most probably because Jabra have decided to use a thicker grade of plastic around the ears where this device will experience the greatest stress.

It’s not so good for music where it clearly cannot cope with the additional bandwidth required to stream good quality stereo audio. Cut-outs are annoyingly frequent. Also I found the maximum volume level way too quiet for noisy places. It would be no good for cycling or on a train - your audio would be inaudible.

I’d also take issue with the excessive lighting. Each earphone has a circular light that appears to be made of a ring of multicolour LEDs. These light up in various colours to indicate the status of the device. Flashing blue, for example indicates that it is on and connected. Constant green indicates that it is fully charged. The consequence of this light-show is that when wearing it you are made to resemble an extra from Blade-runner.

The manual informs you that the lights can be disabled by pressing a pair of buttons at exactly the same time for five-seconds. Unfortunately the device does not remember it’s configuration, and this tedious routine must be done every time the device is taken off charge if you wish to avoid looking as if you have baubles strapped to your ears.

The most astonishing thing about the buttons is how many there are. Nokia’s flawed BH-501 manages a decent set of features using only three buttons on a single side of the headset. Jabra by comparison have decided to place buttons absolutely everywhere.

Each can is dominated by a large round push-button: The left is supposed to make and hang-up on calls. The right is supposed to stop and start audio playback. In practice I found myself forgetting which does which and then most often pressing the wrong button. The same goes for the track-skip and volume-control ‘up-down’ switches on the bottom of each phone. They both feel identical and are easy to press by mistake resulting in unintended calls and irritating pauses.

In summary, I’d say that this machine is good for somebody who mainly uses a headset for talking. Music listeners will find it sub-optimal but not a complete failure. The controls are a nightmare and the lights are excessive and surreal, but despite all these bad-points I expect that the product will last well.

Review: Nokia BH-501 bluetooth stereo headset

Nokia’s BH-501 looks great, sounds wonderful and is very easy to use but is also the most absurdly flimsy product Nokia have ever made.

At approximately £40, the BH-501 seems like excellent value for money. It’s got all the latest bluetooth audio profiles and is a perfect companion for a modern media-phone like my N95 or as audio output from a shiny-new mac-book. It can connect to many devices including almost any mobile phone and with an integrated mic you can make calls (as long as you speak loudly).

I used to use mine for listening to podcasts. I’m sure they would not impress an audiophile, but then again no bluetooth headphones ever could. They were just fine for listening to MP3s. I found the clarity and loudness sufficient to listen in noisy places (I used to wear mine while cycling). Sounds great, right? Unfortunately a silly design means that that your BH-501 will break and become useless long before you get your value from this product.

Did you notice that I refer to this product in the past tense? That is because every one of the three BH-501s I have ever owned has broken. Calling them fragile is an understatement.

In what might have seemed like a bold stroke of the designer’s CAD system, the BH-501 has a sort of folding mechanism where the two arches that go over the ear bend at a hinge to make the device occupy less volume. The hinged component is curved component made of bendy-moulded plastic, that looks like a curved, tapered spline. At it’s thinnest it converges to a width of approximately 5mm diameter. It’s hardly a co-incidence that every one of the devices I have tested fails at exactly this point.

Please believe me - It’s not that I have been unlucky. I’ve been through three of these. Each time I optimistically (stupidly) expected that I had just been unfortunate and that Nokia would never have marketed a fault. Each time I was wrong. All three headphones failed in exactly the same way

My verdict is that this product should be avoided, except for very light indoor use. If you have one of these devices you should never place it round your neck, like you might do with an ordinary pair of headphones. The plastic cannot cope with the torsion which results from normal body movement and will very quickly fail next time you wear them on your ears.

If you are a BH-501 owner, I’d appreciate your comments here. I’m particularly interested to know how quickly the plastic failed and what kind of treatment you gave it.

I believe that Nokia should be quick to admit that they made a mistake here and offer to recall the product. I’d be happy to buy other Nokia accessories, but I feel that to continue to market a product with a known serious fault is somewhat dishonest.
